876 THE AMERICAN NATURALIST. 
The Concilium Bibliographicum.— We are glad to receive, unfor- 
tunately too late for insertion in the present issue, an account of the. 
work of the Concilium Bibliographicum, from which we learn that 
this enterprise is now firmly established, the Swiss Confederation, 
the Canton, and the town of Zurich having voted a permanent 
subsidy for its support. 
The Concilium was founded in 1896, by Dr. Herbert Haviland 
Field, with the view of furnishing zoologists with a more complete 
bibliography than had existed heretofore. The plan is to issue a 
classed card catalogue of current zoological literature, taking into 
account not only all books and papers issued but also parts of 
papers when they treat of distinct subjects. This large undertaking 
has involved an immense amount of work for Dr. Field, as well as a 
very considerable expense, and he should receive the cordial support 
of every zoologist. 
It is not expected that individuals will care to subscribe for the 
whole series of cards, and orders will be received for as small a part 
as any one may want. Every worker in zoology may profit, there- 
fore, by Dr. Field’s labor, and at the same time aid him in this most 
useful and unselfish enterprise.
