under my notice. Some of those that are here listed mayat first 

 appear not to pertain to the subject, but many of the discussions, 

 criticisms, notes, etc., to which reference has been made, although 

 some of them are in general works on microscopy, are of much 

 interest and value to the student, and will be found useful to 

 those who have not access to large libraries. 



The list is divided under the following heads : 



(1) — Eozoon. (2) — North and South America, Bermuda, Lee- 

 ward and Windward Islands. (3) — England, Ireland, Scotland 

 and Wales. (,4)— France and Italy. (5)— Austro-Hungary, Bel- 

 gium, Denmark, Finland, Germany, Holland, Netherlands, Nor- 

 way, Sweden, Switzerland. (6)— Russia and Turkey. (7) — 

 Africa and Asia. The authors* names are then arranged alpha- 

 betically and their works according to the date of publication. 



I mast ask those who may notice omissions or detect errors, to 

 kindly inform me of the same so that I may be able to make cor- 

 rections in a completed supplement. 



I am under great obligations, and return my sincere thanks to 

 the following gentlemen who have rendered me invaluable assist- 

 ance in sending manuscript lists of their papers.

 student. The writer will then feel that his years of tedious and 

 constant labor have been well repaid.
