REPORT OF NATIONAL MUSEUM, 1922.

skins has been installed in the taxidermist shop. This apparatus 

 has made it possible to have our tanning done under proper super- 

 vision and without submitting our specimens to the risks of a com- 

 mercial tannery. The advantages from all points of view can 

 scarcely be overestimated. The taxidermists have prepared about 

 200 skins for study specimens. Our regular force of preparators has 

 cleaned 309 skulls and 85 skeletons, while contract work has resulted 

 in the cleaning of 1,346 skulls and 107 skeletons. Work of this kind 

 is satisfactorily up to date. 



During the first half of the year an accurate count of the speci- 

 mens in the division was made. The results of this count are given 

 in the appended table.

1 Introduction. 



Note.— Grand total, including specimens in Biological Survey, 204,534. There are 1,179 type specimens 

 in the collection of the United States National Museum proper, which are included in the above list. Total 

 type specimens, including Biological Survey, 1903. 



At the same time the Biological Survey took a census of the mam- 

 mals under its care, all of which are from North and Middle America, 

 with results as follows : 



Summary of mammals entered in catalogue of Biological Survey 

 collection, U. S. National Museum, up to January 15, 1922 : 



Total number of specimens 125, 265 



Number of type specimens -r — 724 



The two counts have made it possible to give for the first time a 

 reliable estimate of the actual number of mammals in the National 

 Museum at the close of a fiscal year — a total of no less than 205,201.
