series of reagents as Goodrich employed, under the advice of 

 Professor Gotch ; and I will tabulate the results obtained by 

 me for ready comparison with Goodrich's results. 



The observations of Schaeppi, of Picton, and of several 

 others, on the intra-cellular products of Polychajta, point to 

 the great variety of these cell-contents. But, in order to 

 obtain some farther light upon this difficult problem, it seems 

 to me desirable that the whole question should be dealt 

 with by a competent chemist. It is, at present, somewhat 

 difficult to correlate the various results, or to form a definite 

 opinion as to the function performed by these cells — whether 

 excretory or otherwise,— or the stages by which the varied 

 chemical substances are built up. The whole subject is one 

 of great interest and importance, and I can only give my 

 results for what they are worth. 



A comparison of this table with that given by Goodrich 

 shows that these "granules" agree with the " white gran- 

 ules" in the lymphocytes of Enchytrseus hortensis, 

 which are neither mucin nor chitin. They do not appear to 

 ao-ree with " Chloragogen " — a word of vei-y wide applica- 

 tion.
