This is a striking image of a bright and reaching idea--the use of dogs to find, identify, and alert the presence of a wounded soldier on the battlefield. The dog would be sent out onto the battlefield, where it would find wounded soldiers, after which the dog would retrieve a possession of the soldier's and return to the trenches, and then lead a squad to retrieve the wounded man. That, or the dog would stay and stand guard, barking to alert stretcher bearers the location of the soldier. The dog houses are of a massive construction, like fortified dugouts--I suspect that the camp was far enough front to be subject to bombardment. I'm not sure of the breeds there, but perhaps these are Bouvier des Flandres, or Briard? I can't tell.
A Picture-Book about the Costs of Medical Care was composed by the Julius Rosenwald Fund in 1932. One of the major data visualizations in the short pamphlet was the distribution of medical care according to income--and it comes as no surprise that during the Depression that the wealthiest people are enjoying more medical care than the other classes. The stats are mostly not displayed in this pamphlet so there's not much that I think I can say about them--except that it seems that the class distinctions/percentage in this chart are similar to the William Thompson & Joseph Hickey (2005) class model.
So from the Rosenwald Fund the numbers are described like so (with the addition of the bureau of Labor Statistic's calculated figures for teh purchasing power of the 1932 dollar in 2016):
<$1,299, 15% of the population, ($20,957 in 2016 dollars)
$1,200-$2,000, 35% of the pop, ($34,938 in 2016 dollars)
$2,000-$3,000, 25% of the population ($52,392 in 2016 dollars)
$3,000-$5,000, 15% of the population, ($87,321 in 2016 dollars)
$5,000-$10,000, 7% of the population, ($174,643 in 2016 dollars)
$10,000+, $2.9% population, (greater than $174,643 in 2016 dollars)
The Thompson/Hickey model
Upper middle class 15%
Lower Middle Class 32%
Working class 32%
Lower classes (including the working poor 20%
The bottom two classes in the Rosenwald could constitute the poor and the working poor, making 50% which is what is most in-line with the Thompson/Hickey model. It is a little more difficult to work the numbers and try to distinguish the super rich, rich, upper middle class, and middle class in other models against the Rosenwald graphic. However when you look at two other models the poor and the working poor add up to about the same as above; the Dennis Gilbert model (2002) finds 55% in this category and the Leonard Beeghley (2005) finds 57%. This is real smashmouth statistical surfing, I know, but it does seem as though there is a good correlation between the Rosenwald working class/working poor/poor numbers from 1932 and more recent models.

These images are brought to us by the Irish-born Quain brothers: Jones Quain (1796-1865), an anatomist and professor of Anatomy and Physiology at the University of London; and Richard Quain (1800-1887), professor of anatomy in 1832 at the University of London, then surgeon at North London Hospital, and president of the Royal College of Surgeons. The illustrations are from a later (ca. 1850's) and smaller printing of their beautiful 1844 work The Anatomy of the Arteries of the Human Body, with its Applications to Pathology and Operative Surgery, in Lithographic Drawings with Practical Commentaries.
[This bedside nurse's aid appeared in the July 17, 1869 issue of the Scientific American.]
According to the article, "The inventor of this nursing table has endeavored to afford greater comfort to the sick by providing them with the means of supplying in a measure their own wants during the absence of an attendant. In large hospitals the want of something of this kind has been long felt and in many cases its use in private houses would be a great convenience..." Mostly it was a drinking-and-spit-bucket apparatus--still it would no doubt come in handy and loosen the duties of the nurse somewhat.
J.G. Heck wrote and compiled a fascinating and complex work entitled The Iconographic Encyclopedia of Science, Literature and Art, and was published in America for the first time in 1851 following Spencer Baird’s translation from its original German.
The key to his work is the amount of data displayed on each of the 500 engraved plates illustrating this work and the way in which it is arranged. The design and layout of the 30,000 items on these 500 plates was a work of genius, and for my money it is easily the best-presented complex means of the display of data and objects that was published in the 19th century.
The image above is from one engraved plate featuring 43 aspects of the human eye--beautifully arranged, and somehow fitting perfectly on the 9x11" sheet of paper. It is a work of real design engineering.
This is a large, full front page advertisement for ultraviolet therapy, and appears in the Illustrirte Zeitung (Leipzig) for September 21, 1922. Therapy using UV lamps of various origins was of relatively recent origin (ultraviolet radiation being discovered by Johann Ritter in 1801) as stated in the text here, which gives a pretty lengthy appreciation of the history of the use of crystal lamps, and noting (in paragraph four) that the principle in the invention of such material was Richard Kuch. (Kuch was a physicist and chemist who created the first mercury vapor quartz glass lamp in 1905 and the first mercury vapor high pressure lamp in 1906.) UV treatment does have its proper place in the history of medicine, but it certainly came to occupy a lofty perch in quack medical treatments for home use in curing everything from cancer to gout to dandruff via the "purple light rays". I really don't know all that much about this subject and was reporting on the design aspect of the ad--the treatment of the subject though certainly seems academic, complete with a priced guide to related literature.
D.B. Smith's "On Medicinal Leeches", which appeared in the Journal of the Philadelphia College of Pharmacy (January, 1833, pp 265-271), may or may not have the first illustration in a U.S. journal of a medical leech. Or at least that's according to what D.B. Smith says, who claims that an image of the little critters with multiple jaws and lots of teeth "appeared here for the first time". It seems to be a little late for that to be happening for the first time, as using leeches in medical practice to prevent disease and infection goes back a long way before this article, far beyond the earliest written mention of it goes (in a Galen manuscript, about 2,000 years ago). On the other hand the medical journal was still a pretty new idea at this point in the history of science in the U.S.A--the very first medical (and scientific) journal in general does not appear until 1797 (with the Medical Repository) so it is possible that in the 36 years of scientific/medical journal publishing history to this point it is entirely possible that this short article can claim its "firsts".
The article is not without its very muted bells and whistles, but what attracted me instantly was the bit in it about the leech explorers. The Leech Explorers of 1833--it is an exploit-ish title, perhaps even needing a bit of a Busby Berkeley dance routine to support it in a Leechy Atlas sort of way.
We find out that at about that time, in the 1820's and 1830's at least, there was a bit of a European leech mania. Of course, manias are difficult to explain in their appearance but not so much in their disappearance, and the leeches just got in line with the rest of the other manias, like the dancing mania, tulip mania, bibliomania, arithomania, fortune telling, magnetism mania, and so on.
What happens with the leeches at 1833 is there was a definite leech supply failure--in Paris alone 5 million leeches were used every year, emptying out 300,000 litres of Parisian blood (according to the Encyclopedia Britannica). The demand for leeches was so great that leech dealers would extend their range to Spain, Corsica, Germany, and even to the far reaches of Turkey, and finding no satisfaction, opened their hearts for new and true sources of leeches, and "explored".
For some reason this struck me as enchanting and exotic--images of leech dealers and leech dealer mule trains hauling large buckets of dirt filled with leeches, bumping slowly along at very slow speeds for thousands of miles. And since leeches are living things and need to stay that way in order to function in the medical sense, they need to make the long journey alive and well. I wonder if there were ever leech highwaymen? Or leech saboteurs--competing leech explorer/dealers making life difficult for their competitors, like you might encounter with gold miners. In any event, the Leech Explorers idea was a bright and confused point of light in an otherwise not terribly interesting story about American leeches of 1833.

Dr. Edward Jarvis (1803-1884) conducted a study1 in 1866 to determine how much a factor distance from an "insane hospital" was in regards to people using the facility. It sounds like an obvious-enough question with a probably-obvious answer, but these things are really never so until someone actually looks at the data and extracts an answer. And so Dr. Jarvis performed this function, answering the question once and for all that yes, indeed, the further away you are from a facility the less likely you are going to be to use it.
For example, in my own state of North Carolina, Dr. Jarvis breaks down the rather long and narrow state into five sections, and then lists the number of people per section making use of the state facility in Raleigh.
This item can be purchased from the blog's bookstore, here.
The findings by section and distance as follows:
I, Wake county, including Raleigh; 1 in 4,875 residents used the state hospital
II, 50 miles distant; 1 in 6,433
III, 50-100 miles "from the asylum"; 1 in 9,707.
IV, 100-150 miles from Raleigh; 1 in 10,982
V, 150-250 (+) miles; 1 in 45,790.
This is pretty much consistent with the few other states that I checked.
Jarvis conducted another study that also conclusively stated that the closer people are to an asylum that the more they are subjected to the idea of being able to help/cure the people attending the institution.
Jarvis had a few pages of analysis at the end, establishing a "law of nearness" on the use of facilities. He established that just because the institution is equally available to all (white) people doesn't mean that it will be used equally by all. He suggested that institutions be established in different sections of the state to help make it possible for all people in a state to use the state asylum.
Again, something isn't obvious and correct until it is.
This was some early and instructive medical statistics work conducted by Jarvis, who in addition to being an M.D. served from 1852 to 1884 as president of the American Statistical Association. He completed this survey not long after having tabulated the national statistics of mortality for the Eight U.S. Census (of 1860).

JF Ptak Science Books Post 1479-- (from 2011, expanded)
[Mascagni image(s) source: National Library of Medicine, here.]
Species of explosions come in all sorts of shapes and sizes, and basically release some sort of energy (chemical, nuclear, mechanical and so on), but in the cases we'll look at here they are none-of-the-above. The energy released in these explosions are in the form of potential, a knowledge-driven, controlled and reversibly ordered demolition, a deconstruction in slow motion. The medical "explosion view" for the study of anatomy is a remarkable thing, especially when you considered not only the pre-CT and pre-MRI times, but also the pre-X ray (1895) days of imaging the inside of the body--the images not only show you the bits and pieces alone but also in relation to the other bits around them. The body becomes an archaeological dig, each level preserved so that a viewer could easily see the dependencies and relations between one thing and another.
Take for example Paolo Mascagni's (1755-1815) beautiful Anatomia universale (an example seen above), which was printed in Florence in 1833 and has the look and sensibility of something much later. Mascagni is able to achieve this depth not only from the exploded view, but also for the (somewhat exaggerated) coloring setting the specimen on top of a blank background the combination of the color and the background giving the whole thing a 3-D-ish feel--and if not that, then certainly a living image in which there is some fair amount of depth.
Another version of the exploded view which is also quite effective from the same work by Mascagni is his "exploded thorax", showing a more limited display of the more closely-aligned organs.
When these views appear today--which is generally much more uncommon given the other technical ways of envisioning multiple layers of complex associated items--they have more of a sense of the antiquarian, retro feel to them, though they are no less useful for it. As a matter of fact I still prefer these views for understanding technical and engineering and architectural complexes than anything else. And the modern master of this genre for me is Stephen Beisty, who performs his magic mostly in the tech and engineering fields, but who occasionally dips into the messy wet stuff of biology, as we can see in this fabulous exploded view:
There are of course many other examples of (drawn) exploded views in the history of anatomical illustration, but I think these will do for now as good examples of the art.
This advertisement for a remarkable new and 'painless" therapy for involutionary melancholia looks to me strained and strangely Ken Keasyian, John-Forbes-Nashian. The disease--not actually recognized as such by the DSM-5--was said to be lessened by "electro-tonic therapy", which looks to me to be electroconvulsive therapy, or ECT. Evidently before treatment for illness like involutionary melancholia were available via antidepressants the ECT worked in some number of cases. Still to me this looks like all kinds of bad.
Here's an extraordinary find, a bump in the grazing field in the Scientific American Supplement for January 19, 1878. The article is about dust--but not the cosmic dust that some folks say is what is being seen in the Big Bang (and not a background radiation signature), nor is it like the dust equation nor the dust of Einstein's great dust paper of 1905. It is more like a lower-level plague dust as we see in Arthur Rothstein's iconic dust bowl photograph made in parched Oklahoma in 1936. It is about the residue of industry and commerce that did't get carried of by the mysterious carry-off winds associated with the high and higher chimneys of Victorian London and other industrialized cities, and the leftover bits of the operation of daily cosmopolitan life involving say horses and trains. It is an article about the significant particulate matter of dust, which we know today is a high-percentage contributor to air pollution, not to mention the low-level "atmosphere" of the kicked-up business that people would breathe in every day.
And, evidently, this dust was very heavy-metal rich in composition, which is not so good.
The article is "Street Dust", and the author, Henry G. DeBrunner (who would become professor of chemistry at the Pittsburgh College of Pharmacy), decided to take a look at the dust of Pittsburgh and compare it to reports of the dust of major European cities. He notes that Paris and London and other cities consist of 35% of "metallic iron, given by the shoes of horses to the stones, besides from 30 to 40% of good glue from the hoofs". Now that seems an extraordinary figure, and surprising too in many ways that it came from horse shoes.
[Source: an advertisment from Scientific American, volume 79, 7 January 1893, back wrapper.
DeBrunner conducted a study at Thirtieth and Smallman Streets (Pug) and found out that 30% of the sample of dust ("a deep black color") consisted of silic acid, 26% of "fixed carbon", ferric oxide at 12%, sulphuric acid at about 1%, gluten 1%, Metallic iron 8.55%. The details of how all of this was extracted can be seen below, where the entire article is reproduced. There were other samples, and it is interesting to note that in one sample near horse tracks contained 32% heavy metal and lots of glue.
The entire article, January 19, 1878, Scientific American Supplement, No. 107:
"For my part I deem those blessed to whom, by favour of the gods, it has been granted either to do what is worth writing of, or to write what is worth reading; above measure blessed those on whom both gifts have been conferred"--Pliny the Elder
Johannes de Kehtam's Fasciculus Medicine (printed in Venice in 1500) was the first anatomy to be printed with illustrations. Ketham was described as a German doctor living in Italy and may well have been Johann von Kerchheim, a German practicing surgery and medicine in Venice during he 1470'), and who wrote a series of tracts on various aspects of medicine which were then collected into this single bound volume. The illustrations are spectacular and to me have a very modern sensibility in their mid-Renaissance woodcut legacy--the look very clear and concise, are well proportioned, nicely labeled, and give plenty of free rein to open and blank spaces on the woodblock. The only time these images really "fail" is when they appear in color--a process that would've been undertaken privately, by the purchaser of the book, who would have contracted with an artisan to color the book. The images in almost all of the cases of coloring that I have seen just do not match the elegance and brilliance of the original with no color.

Its interesting to make a quick note on the books on display on the bookshelf behind the seated figure of Petrus de Montagnan (who is consulting classic texts in medicine as his three patients awaits his attention): the books include Aristotle, Hippocrates ("ippocrate"), Galieno (Galen), Avicenna (980-1037), Rasis (Ibn Sina, Rasis, Razi, Al-Razi, c.865-925), Mesue, Yuhanna bin Masawayh (c.777-857), and Averroes (1126-98), Abu el-Walid ibn Ruchd, Abu el-Walid ibn Ruchd. On the shelf to the right we see a copy of Naturalis Historia by Cais de Plnii (Gaius Plinius Seocndus, also known as Pliny the Elder, who lived from 23-79 A.C.E and who held forth on all knowledge from everywhere during the first century).
It is the anatomical illustration where the un-named artist is most brilliant--the lines are sharp and crisp, the spacing elegant, and the imagery very clear. It is just lovely work:
The collaborative work of anatomist Wilhelm Braune (1831-1892) and artist C. Schmiedel (fl. mid-1800s) produced a singular work, Topographisch-anatomischer atlas nach durchschnitten an gefrorenen cadavern...(published in Leipzig in 1872), which was an oustanding example of high-realism in the art of anatomy. This book is pretty much right-to-business, with no extraneous bits as had appeared in anatomies fo rcenturies. And even though these practices had pretty much expired by the first quarter of the 19th century, Braune/Schmiedel was ever more so detailed and simple--their design was fabulous, and their detail light and exceptional.
They also made use of sliced frozen sections of cadavers, which seems to give their work that crystalline touch. The first image looks at the brain from top-to-bottom, while the second reverses the view, which is in itself somewhat unusual, even in 1872.
Looking into a very finely-produced skull from an earlier period in the work of the anatomist Govard Bidloo (1649-1713) and the artist Gérard de Lairesse (1640-1711) in their Ontleding des menschelyken lichaams, (which was printed in Amsterdam in 1690) we find a bit of a different story.
One interesting aspect of Bidloo is that he can be extraordinarily detailed and still lend a rather baroque still life to engage his subject--like the skull with musical score, above. There's no reason for the added bit of scenery, its just a luxurious background for the anatomy. And then there are examples like this incredible facial/neck dissection below, which is very hard-core realistic, just as what you might find on any dissecting table, which most assuredly did not come equipped with pen/ink/music score. Bidloo here is ultra-real, more so than the greater majority of anatomist/illustrators. [Ontleding des menschelyken lichaams...printed in Amsterdam, 1690, as a copperplate engraving with etching.

In 1664 Philipp Jakob Sachs (Sache de Lewenbheimb) wrote an influential book on the circulation of the blood. It was the advanced work of a learned man, a naturalist and physician who was also the editor of the Ephemerides Academiae naturae curiosorum, which was the first journal in the field of natural history and medicine and one of the founders of the Academia Naturae Curiosorum (Leopoldina). His work came 40 years after the great work by William Harvey, who published Exercitatio Anatomica de Motu Cordis et Sanguinis in Animalibus in 1628, a work in which he essentially brought the idea of circulation of the blood into the modern age, building on earlier ideas of Michael Servetus, whose 1561 work on circulation (and his religious ideas) brought him to be executed by flames.
For centuries the pulse was a vaguely understood thing reaching back into the murky medical past as far back as Galen. The association of course was with the heart, and the association of the heart was as the great controlling center of all function and control of the human body—a theory that reached far forward into the 16th century.
Servetus (physician, cartographer, theologian, writer and general all-adept Humanist of a high order) was in trouble with the church for many reasons, not the least of which was trying to dislodge the theory of the heart as sacred and the seat of wisdom. But he did establish that the heart was an organ, which didn’t sit well with very many people, least of all the Calvinist court in Vienna which found him guilty on many anti-Humanist grounds, including his anti-Trinitarian Christology, which made him a reviled figure to Catholics and Protestants. He was tried and found to be dangerously heretical, and sent to the flames.
Harvey withstood blistering attacks on his correct statements on the circulation of the blood (costing him nearly all the patients in his practice), though he at least lived to see a brighter day: Servetus, on the other hand, didn’t, and was burned at the stake for his heresies, one of which his attack on the spiritual heart.
In any event, the frontispiece to Sachs' work is an interesting allegorical composition showing a connection between the place of the very prominently featured heart in the circulation of the blood, and the water cycle, and the cosmos of creation (the breath of life coming from the winds of the Sun and the Moon).
