Edward Claypole, The Scientist—Comstock. 9 
few weeks after her husband’s decease) and who knew her 
attainments and qualifications as helpmeet companion, at least 
a word of acknowledgment here of her work for science. Rev- 
erently conning the files of Dr. Claypole’s papers, records and 
memoranda there come up frequently mute, but striking, tes- 
timonials to the intimate association of the wife with his tech- 
nical pursuits. She had prepared for the examinations leading 
to his degrees and shared in his intellectual life as few others 
could. Her enthusiasm and honest pride in his work were in- 
spiring spectacles, and her own description of his achieve- 
ments (quoted later in this sketch) is an admirable illustra- 
tion of the share she always had in his life-work. In her death, 
American geology and geologists have lost a kindred spirit. 
Her absence from the annual meetings of the American Asso- 
ciation for the Advancement of Science, will be keenly felt by 
those who were wont to greet her and him as inseparable ele- 
ments upon such occasions. Her last words to the writer were 
in reference to such an occasion when the names of mutual 
friends were happily recalled; and the greetings sent to her in 
remembrance of her husband from the Denver meeting, in 1901, 
at the time of his decease, were cherished among her precious 
jewels. 
Professor Claypole’s paper on pre-glacial geology antago- 
nized pet theories of earlier workers, although his arguments 
were largely supported by their own statements of facts. Possi- 
bly for this reason, his abilities were not utilized by the Ohio 
Geological Survey. But in October, 1881, when leaving An- 
tioch, he was called to the Second Geological Survey of Penn- 
sylvania, being assigned to Perry and Juniata counties. ‘hen 
began another distinct period in his life. He was for a time 
called away from the study of the Ice Age and its antececent 
era to the contemplation of Silurian and Devonian fossils, and 
to the solution of geognostic problems. 
His discoveries in this field were epoch-making, and it 
was fortunate for his fame that his skill in drawing was no 
less remarkable than his powers of description. His maps 
and illustrations of fossils were not redundant, but always 
accurate and perspicuous. Many of the original sketches de- 
picting the type specimens are now preserved in his library, 
convincing proofs of the importance of his researches.
