66 REPORT OF NATIONAL MUSEUM, ‘1921. 
way. The limit of this sort of selection is quickly reached, however, 
and it is important that additional case room be provided without 
delay and that means be found of mounting promptly all material 
needed for permanent preservation. About 26,000 specimens have 
been mounted during the year. These have been recorded, chiefly 
through temporary clerical help. The segregation of type and dupli- 
cate type specimens from the main herbarium has been continued 
as opportunity offered, mainly in connection with other work, and 
10, 136 specimens have now been distinctively labeled, catalogued, and 
placed in individual covers in the so-called type herbarium. 
At the beginning of this part of my report the general tendency 
of the work of the preparators has been mentioned. Apart from 
the specimens which found their places in the exhibition series much 
work was spent on study material for the various divisions. Skins 
of mammals and birds were made up or repaired for the study 
series, many dry preparations made for the division of reptiles; 
skeletons and skulls cleaned whenever needed for study. Mr. 
W. L. Brown, whose remounting of the African leopard I have 
already alluded to, also mounted a South American brocket deer 
and a mule deer, which were placed in the exhibition series. A 
large number of mammal skins were worked up, birds dismounted 
and made into study skins, etc. Some time before his death Mr. 
Wood had already begun to instruct Mr. Brown in his way of 
preparing dry bird skins, as well as in his own particular methods 
of mounting birds which had given him such a high rank among 
bird taxidermists. It is therefore felt that Mr. Brown and. Mr. 
George Marshall in the future will be able to fully take care of 
this branch of the exhibits. Mr. Marshall, in addition to a large 
amount of repair work, skinning fresh material coming in from local 
collectors and the zoological park, tanning, etc., has mounted a num- 
ber of smaller mammals, including several monkeys. Mr. J. W. 
Scollick, the osteologist, in addition to cleaning a number of turtle 
skulls and bones, prepared 179 whole skeletons, some exceedingly 
delicate. Among the lot were no less than 155 bird skeletons, and 
10 skeletons of rats, which were mounted for the Bureau of Animal 
Industry, Department of Agriculture. Twelve skins of the same 
series of rats were also mounted by Mr. Marshall for the same bureau 
as an exhibit to illustrate the result of certain feeding experiments. 
The bone-cleaning work under Mr. Scollick’s supervision resulted in 
the cleaning of 57 mammal skeletons and 130 large mammal skulls. 
Mr. C. E. Mirguet’s time was to a great extent taken up with two 
tasks, the preparation and cleaning of the Florida whale skeleton, 
donated by the Miami Aquarium Association and mentioned above, 
and the building of a drum for the tanning of mammal skins. The
