These blanks did not take the place of note books but were meant merely to con- 

 dense and systematize the records made in the note books. 



The other form of blank may be called the collective blank. A sample of it appears 

 below. It is a modification of a form used at Mr. Agassiz's Newport laboratory.

Blanks of this form were passed from one worker to another, and each person 

 entered in them the forms which he had found as taken in a certain net at a certain 

 time and in a certain location. The blanks thus serve to show the way in which the 

 forms are associated and their relative numbers under different conditions at different 

 times. To properly till one of these blanks was usually the work of six observers for 

 the greater part of a day. 



For the records of parasites there was a third form of blank, designed by Dr. 

 Ward and shown in the accompanying copy. It is intended to bring together certain 

 data concerning the animal infected and the numbers and kinds of parasites.
