Champion, P. De la Spectrometrie Spectronatrometre.
Paris: Librarie Polytechnique de J. Baudry, 1873. 1st edition. 15pp. Original printed wrappers. Very good condition. This rare pamphlet--unlocated in OCLC/WorldCat was written by Champion with H. Pellet and M. Grenier, and is illustrated with a full-page original photograph of the apparatus. There is one old rubber stamp from the former owner (The Library of Congress) and a few bends here and there in the wrappers; otherwise this is quite a nice pamphlet. $225.00
