Psyche 
[ March 
1870, and later, 1873-1874 was an assistant in the Museum. 
While here he prepared the notes to Hentz’s spiders of the 
United States and the article on cave spiders of Indiana 
and Kentucky (1875). 
He had already decided to study spiders, had collected 
in over 100 localities in the New England states, and had 
amassed a collection of more than 300 species. 
Early in 1875 he left the Boston Society to spend more 
than a year in Europe. While there he was enrolled as a 
student for a short time at the University of Leipzig (Oc- 
tober, 1875 to April, 1876) and later (May to July, 1876) 
at the University of Jena, but apparently he spent much 
time collecting spiders and becoming acquainted with the 
arachnologists of Europe, particularly Cambridge, Simon, 
Koch, Thorell and Ohlert. He had taken to Europe his 
collection of New England spiders and from Leipzig in 
December, 1875, wrote an article comparing them with 
those of the European fauna. 
Returning, he again engaged in drawing and prepared 
many of the colored plates in Eaton’s “Ferns of North 
America” and also many in Packard’s “Monograph of the 
Geometridse.” 
In 1877, he gave eight lectures on zoology and six on 
spiders at the Summer School of Biology in Salem, and in 
1878 delivered another series of six lectures on spiders. 
He became a curator in the Museum of the Peabody Acad- 
emy of Science where he spent an hour each day with the 
visitors and prepared a Guide to the Museum. In 1879 
he also gave instruction in the zoological laboratory at 
Salem. 
He spent some time at Albany, N. Y., making drawings 
for Prof. A. Hall, and later (about 1880) went to New 
Haven, where he was appointed assistant to Professor A. 
E. Verrill. He made a host of drawings for Verrill, and 
prepared the famous models of the great squid and octopus 
now in the Museum of Comparative Zoology at Cambridge 
and in the National Museum at Washington. For these 
models he was awarded a medal with an elaborately en- 
graved certificate at the International Fisheries Congress
