of the history of evolution which appears in the introduc- 
tion to all later editions of the Ovzvzgzn. So too would 
my friend, Professor Osborn, have given high honour to 
Prichard in his interesting work, /vom the Greeks to Dar- 
win. It is an anomaly that such works as the Vestzges 
should attract attention, while Prichard’s keen insight, 
sound judgment, and balanced reasoning on many aspects 
of organic evolution should remain unknown. 
I am very far from maintaining that these most in- 
teresting anticipations in any way diminish the credit of 
those recent writers who have treated the same subjects in 
greater detail and of course independently. The interest 
evoked by Dr. Davis’ discovery in the literature of evolu- 
tion is mainly due to the work of those recent authors by 
whom the whole subject has been brought into the light of 
day, and the attention of every intellectual man and woman 
has been compelled. 
The limits of space oblige me immediately to proceed, 
after this too brief introduction, with a detailed statement of 
Prichard’s arguments and conclusions, which will be found 
to justify, in the fullest manner, all that I have said in his 
praise. 
It has already been said that the arguments referred to 
are found in the Aesearches into the Physical Flistory of 
Mankind, vol. i. (London, 2nd edition, 1826). They are 
included in the seven sections of the first chapter of Book 
ip: 525), which is-entitled’a “General Survey ofthe 
Causes which have Produced Varieties in the Human 
Species, with Remarks on the Origin of Nations and on 
the Diversity of Languages”. The first chapter treats 
““Of the Causes which have Given Rise to Varieties in the 
Human Species”. In the first section of the first chapter 
the author admits that it is fruitless to seek for a complete 
explanation of the causes which have produced the varieties 
which are witnessed in the human species. “The origin 
of the varieties in the breed is enveloped in the same 
obscurity which still hangs over every question relating to 
the theory of propagation.”
