1862.] MUSEUM OF COMPARATIVE ZOOLOGY. 85 



unpleasant and laborious task, the extent of which may be appre- 

 ciated, when I say that Mr. Putnam alone has revised about G0,000 

 specimens of fishes preserved in alcohol, and that Messrs. A. Agassiz 

 and Putnam have recently unpacked and distributed, according to 

 their families, the contents of more than two hundred barrels of alco- 

 holic specimens. 



During the past year, another important apparatus for the illustra- 

 tion of specimens of natural history has been added to our establish- 

 ment, — I allude to the photograph-room organized by Mr. Glen, — 

 but, from want of time, only a few experiments have thus far been 

 made to reproduce microscopic preparations. But, if we have not yet 

 been able to do much ourselves in that direction, a collection of pho- 

 tographs is nevertheless begun, thanks to the kindness of Professor 

 Valenciennes, who has sent me a number of those illustrations, made 

 at the Jardin des Plantes, and of Mr. Theodore Lyman, who has for- 

 warded a large number of photographs, representing the different 

 races of men, made chiefly from casts, collected during the several 

 scientific expeditions round the world, directed by the government of 

 France for the last half- century.
