“Tf the experiments themselves narrated by Dr. Bastian are 
of a startling character, the arguments which he deduces from 
them are not less so. ... We are bound to confess that the 
sceptical feeling with which it is natural to regard an unproven 
and unpopular doctrine has in great measure disappeared, when 
the method of slow and cautious examination adopted by him 
has been carefully studied."—Pad/ Mall Gazette. 
“ Dr. Bastian, convinced that he has a sure case, very wisely 
takes care to do his opponents the fullest justice. And the 
straightforward manner in which he meets their arguments can- 
not fail to invite the confidence of the impartial reader.”— 
Examiner. 
“These are the questions which have stirred hot controversy 
for centuries, and which Dr. Bastian has answered, once for all, 
by his experiments. .. For the present it is enough to note a 
great stride taken in biological science, and to leave the 
philosophy of the future to make out what it may from its 
newly-won stand point.” —Saturday Review.
