30 JMEMOIU OF CAMI’Bill. 
(lays with the discoveries of his own time, and dis- 
plays a laudable anxicHy that every valuable fact, 
once ascertained, shall not be again lost to the ar- 
chives of science. 
The introduction to tliis curious work on Mon- 
keys, is mainly occupied in discussing what spe- 
cies were known to the ancients ; and in this con- 
nection he introduces about twelve of them to our 
notice. This investigation naturally leads our author 
to an interesting question, viz. How far the an- 
cients, and especially Galen, in the composition of 
his great work on anatomy, acquired his Itnowledge 
directly from the human subject, or how far it was 
inferred from the structure of the lower animals, 
especially those most approximating to man, such as 
the orang-outang. It would occupy too much time 
to attempt even the shortest analysis of his (ibserva- 
tions and arguments on this subject, which, how- 
ever, are extremely pertinent, and such as could not 
easily be controverted. His conclusion is that Ga- 
len, the favourite physician of Marcus Aurelius, and 
probably the most popular, as the most famous phy- 
sician which Horae ever saw, had never dissected a 
human subject, and made no use of such dissection 
in the composition of his works on anatomy, and 
other departments of medicine which have come 
down to our times. 
Tlie body of the work is divided into ten chapters, 
which treat of the nomenclature of the orang-outang; 
its classification, involving that of the species most
