Biographical sketch of Charles Wachsmuth, — Keyes. 135 
Russia and Bohemia, and a large amount of material from 
Mesozoic and later formations. The collection was enlarged 
further by extensive exchanges with collectors in this country 
and Europe, and by having collectors in the field. Liberal 
purchases for the library were made, and when work was 
commenced on the monograph nearly the whole crinoidal 
literature, from the time of J. S. Miller to date, was at hand. 
By examining the titles of their publications it will be noticed 
that Wachsmuth and Springer took very little pride in des- 
cribing new species, their attention being directed mainly to 
the morphology, with a view to classification, and to the 
revision of work of the earlier writers. As the work of the 
monograph was nearing completion Prof. Alexander Agassiz, 
director of the Museum of Comparative Zoology, offered to 
publish it in the best style possible as one of the memoirs of 
the Museum and in this form it appears as a model of typo- 
graphic art. 
Mr. Wachsmuth was a fellow of the American Association 
for the Advancement of Science, of the Geological Society of 
America and of the Iowa Academy of Science. Of the latter 
he was at one time vice-president. He was also a correspond- 
ing member of the Philadelphia Academ} T of Sciences and a 
member of the Imperial Society of Natural Sciences of Mos- 
cow, Russia. For many years an extensive and intimate cor- 
respondence has been carried on with leading scientists of 
this country and Europe. That which passed between the late 
Dr. P. Herbert Carpenter and Mr. Wachsmuth during the last 
ten years would alone fill a large volume. 
For many years Mr. Wachsmuth has been in such delicate 
health that he has had to spend the winters in the South. The 
earl} T spring months have been spent in the mountains of Ala- 
bama, Tennessee and Kentucky, where immense collections of 
both crinoids and blastoids have been brought together. On 
all of these trips he has been accompanied by his faithful wife, 
who is herself an excellent and indefatigable collector, ah en- 
thusiastic worker and an admirer of all that pertains to fossil 
crinoids. Indeed it may be questioned whether she has not 
found as many and as rare specimens as the savant himself. 
Were it not for her tutelary presence the monograph of Amer- 
ican crinoids might never have seen the light of day.
