the University of Jena, and published in Berlin in 1868. But 
first let me quote the following passage from the last edition 
of Sir Charles Lyell's Principles of Geology (published also in 
1868), as cited by Professor Kirk in a paper read before the 
Institute in February, 1869, “ On the Doctrine of Creation 
according to Darwin, Agassiz, and Moses ” : — * 
“ The doctrine of the pristine fluidity of the interior of the 
earth, and the gradual solidification of its crust, consequent 
on the loss of internal heat by radiation into space, is one of 
many scientific hypotheses which has been adhered to after 
the props by which it was at first supported have given way 
one after the other.” 
Those who remember Professor Huxley's discourse in Sion 
College in November, 1867, will simply be amazed that he is 
one who even still publicly adheres to the nebular theory, after 
all its props have gone ! In the Academy (which is called a 
“ record of science,”) he thus writes in October, 1869 : — 
“ Considering that Germany now takes the lead of the 
world in scientific education, and particularly in biology, Mr. 
Darwin must be well pleased at the rapid spread of his views 
among some of the ablest and most laborious of German 
naturalists. Among these, Professor Haeckel, of Jena, is the 
Coryphseus.” .... “Full justice is done to Kant, as the 
originator of that c cosmic gas theory,' as the Germans some- 
what quaintly call it, which is commonly ascribed to Laplace. 
.... It is necessary to remember that there is a wider 
Teleology, which is not touched by the doctrine of evolution, 
but is actually based upon the fundamental proposition of Evo- 
lution. That proposition is, that the whole world , living and 
not living, is the result of the mutual interaction, according to 
* Journal of Transactions of Victoria Institute, vol. iv. p. 65.
