RISE AND PROGRESS OF ZOOLOGY. ir 
We have, indeed, commenced the publication of a 
similar collection*, now so much wanted for our 
public libraries and institutions; but it is highly 
probable that so few copies will be printed, that the 
entire work will only be in the possession of the 
original subscribers ; and thus the main object of 
the undertaking will be but very partially accom- 
plished. Bonnet+, the celebrated -philosopher of 
Geneva, influenced, probably, by the example of 
Reaumer, published two volumes upon insects. But 
both these authors were surpassed by the illustrious 
Baron de Geer {, who, in the year 1752, gave to 
the world his first volume of Mémoires, which he 
subsequently extended to six others. Every ento- 
mologist who has had occasion to mention this in- 
valuable work, concurs in bestowing upon it their 
unqualified praise; not only for the admirable and 
interesting details it contains on the structure and 
habits of the insects described, and the beauty of 
the investigations it narrates, but for the just and 
comprehensive views it unfolds on natural arrange- 
ment. It is a subject of much regret that this work 
is of such exceeding rarity as to be quite unpro- 
curable. We have never been successful in meeting 
with a copy for sale; and although it was soon
