11s The American Geologist. February, 1892: 
cosinic tides, and on meridionality in the earth's structural features, 
had been submitted, in 1882, to Prof. James D. Dana. Later he 
proposed to bring them under the notice of Dr. J. E. Hilgard, 
of Washington; but no criticisms or judgments could be obtained, 
professor Hilgard saying he was not familiar with that range of 
investigation. His conclusions on the evolution of heat by pro- 
cesses of contraction he brought before the Ann Arbor Scientific 
Association (of which he was president) on the occasion of two 
meetings, in the hearing of professors Harrington and Wead, 
likewise the subject of annulation of nebulous masses, and the 
width of the resultant ring, with a view of eliciting opinions. 
Twice Prof. Wead was invited to his study for the discussion of 
certain points—especially M. Faye’s modification of the -‘nebular 
theory” as presented in Comptes Rendus (xe, 687-43); but the sub- 
ject was new to Prof. Wead. 
Whatever new processes or results, therefore, there may be 
found in World Life were worked out by its author in complete 
isolation from all living thinkers. Very much of it was pioneer 
work, and the mathematical instrument employed had been long 
disused. He felt that great danger existed of falling into some 
grave errors, and he knew that as soon as they were in print and 
beyond recall, there would be a class of scientific crities who 
would take any pains to demonstrate their smartness. He greatly 
desired to submit points in his manuscript to the examination of 
experts. but there seemed to be nobody prepared to act in that 
capacity. He therefore had to assume all the risks or forego the 
publication. 
It was during the concentration of nervous and mental energy 
on this volume that he was called on, during the disability of Dr. 
Bb. F. Cocker, both by the president of the University and by Dr. 
Cocker himself, to conduct the latter's class in speculative philos- 
and 
ophy. He continued Dr. Cocker’s method—a daily lecture 
he here drew upon his manuscript volume on ‘‘Intelligence and 
Religion;” and he put a synopsis of the ‘‘Theistic Argument’ 
into printed form, in all its ramifications, for the use and at the 
instance of his class. In a similar manner he condensed, into a 
synopsis of eight octavo pages, his whole work (yet unpublished) 
on ‘Intelligence and Religion.”’ In consequence of this double 
duty it appears that one of the secondary effects of the malady 
with which he was suffering, as made apparent by the post mor-
