JF Ptak Science Books Daily Dose from Dr. Odd
There is something exceptional about the exceptional. In this case, the category is maps, and in this instance the map that takes us away, far away, from the expected or standard is one showing the flow of human hair streams. (It fits very nicely with other exceptional maps found on this site, like Maps of the Cosmos of Moles--just browse the "maps" section in the archives.)
This unlikely title is the creation of Dr. Walter Kidd (Fellow of the Zoological Society, London) and his attempt to reconcile the the influences of gravity, inheritance, genetics, Weismannianism, and other assorted biological bits via his study of hair growth patterns. The article appears in the (many) pages of the Scientific American Supplement for 13 September 1902, on page 22, 328. (Yes, the Supplement was paginated consecutively over dozens of years of publications, a cumbersome manner of ordering an 8-foot stack of paper over dozens of volumes.) In any event, this was an article to simply explain some of Kidd's ideas and the chart that would appear in a more lengthy treatise of 153pp published in the next year by Adam Black. Contemporary views of Kidd's book were not very supportive of his work. I should add that I was attracted to this article solely for the possibility that this may well be the first map of directional hair growth. (I think the idea is pretty interesting, but I'm just not in the mood for it presently.)
