and water-samples come in so fast at times that it is exceedingly 
easy to make mistakes in reading and recording. Any attempt 
to hurry means error, and should the recorder fail to enter a 
single catch the entire day’s work would probably be vitiated, 
because of the difficulty of determining where the error occurred. 
There is no one thing upon which success of the work depends 
more than on trustworthy recording.

Although a library is so vital an adjunct of any institution of 
scientific research, that of the Marine Biological Station at La 
Jolla is unfortunately but meagerly developed. The main 
reliance thus far has been on the library of the University of 
California. The supply of books proper consists of something 
less than five hundred bound volumes, but these are supple- 
mented by a much larger number of pamphlets and reprints, and 
by the considerable library of the director. The cards of the 
Concilium Bibliographicum are provided, and the pamphlets are 
arranged in accordance with the system employed by that institu. - 
tion. The subscription list of journals contains only fifteen of 
the great number that would be requisite to make a really 
adequate working library for such an enterprise. No depart- 
ment of the station is in sorer need of enlargement than this.
