[Published in twenty-six fascicules ; the first twenty-five under the title : 

 "Osteographie; ou, description iconographique comparee du squelette et du 

 systeme dentaire des cinq classes d'animaux vertebres recents et fossiles, pour 

 servir de base a la zoologie et a la geologic par M. H. M. Ducrotay de Blain-

 par M. J. C. Werner .... Paris, Artkus Bertrand, . . ." [1839-1855.] 

 The twenty-sixth and last fascicule was issued with the special title above

 and index, by the Baillieres in 1864. The subscription price w r as 2 francs 35 

 centimes per plate ; the price of the twenty-sixth livraison, 45 francs ; and of 

 the whole, on completion, 800 francs, "aulieu de 961 fr."

 several fascicules has doubtless devolved upon many investigators, as upon the 

 writer, much trouble and annoyance in ascertaining them, and to save to 

 others similar trouble, a collation is here presented, the dates having chiefly 

 been ascertained from Wagner's annual reports in the "Archiv fiir Xatur- 

 geschi elite." The appearance of successive fascicules has not been noticed in 

 the "Bibliographic de la France." 



The titles of the respective monographs given below are those at the upper 

 fourth of the first page of each monograph, and which are the only special 

 titles published. 



The work is more remarkable as a methodical repertory of facts respecting 

 superficial osteological details, than as a digest exhibiting acute appreciation of

 or orthodox view r s respecting classification and the geological succession of
