PAGENSTECHER’S GENERAL ZoGLocy.'—The third part of this 
work was only received during the past summer, and though the 
fourth part is promised for the present year, we will not wait for 
its appearance before calling the attention of our readers to what 
appears to us a most valuable work of reference. It is planned 
somwhat differently from other zodlogical manuals, being writ- 
ten mainly from the side of comparative anatomy. The first part 
is divided into three books, the first being introductory, the 
second treating of the nature of animal bodies in general, this 
caption including a discussion of individuality and pleomorphism ; 
while the third book treats of the subdivisions of the animal 
kingdom, with a free discussion of the doctrine of species. The 
second part appeared in 1877, and treats of the organization and 
functions of animals, the entire part being devoted to the organs 
-of digestion and nutrition, and of circulation. The third part 
the part of the author. 
HARVARD LIBRARY CATALOGUE OF SERIALS.2—This most useful 
publication grew out of the efforts of the author to bring about 
some degree of coöperation between the different libraries in and 
about Boston, by which valuable and costly works should not be 
duplicated, but that each library should aim to complete their 
series of works in separate departments. As the first step 1n 
this important reform was the preparation of a bibliographical 
list of all scientific serials, whether those now in course of publi- 
cation or not, the labor was entrusted to Mr. Scudder, who has 
brought a special aptness and zeal to such work, together with an 
exactness and care in treatment characteristic of all his writings. 
As it stands, the volume will be in constant use by the naturalist,
