HISTORY OF THE MUSEUM 
sented by entire broods showing the variation and intergradation of 
the species. 
About 13,000 butterflies, moths, beetles, grasshoppers, wasps, etc., 
were contained in the collection presented by Mr. James Angus in 1891. 
The Harry Edwards collection was one of the largest private col- 
lections in the world. It numbered 150,000 specimens (60,000 lepidop- 
tera), many of which were types, and 20,000 species, gathered from 
all parts of the globe. It was purchased in 1892 for $15,000, $9,600 
of which was received from friends of Mr. Edwards in response to an 
appeal from a committee headed by Mr. A. M. Palmer, which had been 
organized to secure the collection for the Museum. 
The Schaus collection comprises some 31,000 specimens of butter- 
flies and moths and was presented by Mr. Wifliam Schaus in 1897 
and 1906. About 5,000 specimens of the collection representing the 
principal known genera of Old World moths were gotten together 
by Mr. Schaus as a study collection for comparison with New World 
forms. It contains many type specimens and species authentically 
determined by comparison with British Museum types, a feature 
making the collection highly useful to specialists and students. (Esti- 
mated value of Old World Collection, $10,000.) Some 26,000 speci- 
mens were gathered by Mr. Schaus during three years' search in Mexico 
and Central and South America. 
A series of butterflies and moths from Africa, India, and other 
parts of the world was presented by Mr. Wilham Sachs in 1900. It 
contained about 300 specimens, many of which were very rare. 
About 500 butterflies were collected in Sumatra in 1895 by Mr. 
Rudolf Weber. Almost all of them were new to the Museum collec- 
tions. Seven hundred and fifty were collected by Mr. F. C. Nicholas 
in Honduras and U. S. of Colombia in 1895.
