The results of his work upon the Pennsylvania survey were 
important and extensive. We can best epitomize them in the 
words of the good wife who but briefly survived him, ‘as she 
gave them to me from her own intimate knowledge of his zeal- 
ous labors through that brilliant period of his life. She writes: 
“The Survey extended over Perry and Juniata counties and was 
the occasion of some of his most important contributions to palzon- 
tology and geology. It was here that the great fiad of tne Paizeaspis 
remains was made, the, at that time, oldest, geologically speaking, 
fish remains known. They came from the Silurian (Upper) and the 
establishment of their true antiquity on unquestionable geological 
and paleontological evidence was a task involving the most careful 
and laborious work, one that only a man possessing almost infinite 
patience, greatest delicacy of touch and an almost. dogged determi- 
nation could accomplish. The small scales, or plates, that were 
found had to be ground down thin enough to demonstrate micro- 
scopically their true bony structure. Edward Waller Claypole had 
none of the modern apparatus for rapid grinding, and had to work 
by hand. The extreme brittleness of the material rendered many 
efforts. necessary before final success was achieved. The further es- 
tablishment of the age of the rocks was one involving great care and 
accuracy of observation and deduction, but when established it was 
beyond question and, try as they might, other geologists could not 
break the evidence, and to America belongs the honor of having the 
oldest known remains of fossil fish; previously the oldest had been 
in England. Since that time attempts have been made to show that 
still older ones exist, but the evidence for these is not yet at Jeast 
beyond question. Besides this special piece of work, the survey 
resulted in discovering many interesting new species of fossils and 
also the working out of general geological problems in rock torm- 
ation (and earth movements) making the time spent of great rich- 
ness to him, personally, in geological experiences.” 
Sixteen important papers were contributed by him to vari- 
ous scientific associations while engaged upon this survey and 
twelve more were published as direct results of this work in the 
years succeeding, to 1887. 
The Pennsylvania Legislature having failed to provide for 
the full prosecution of the survey, professor Claypole accepted 
a call to the chair of natural science at Buchtel College, Ai ron, 
Ohio, established in 1883, being the founder there of that de-
