January 14.. — A series of specimens of zinc ore, were 

 received as a donation from Mr. J. Hitz, which were referred 

 to Mr. P. T. Tyson for examination. Dr. Geddings delivered 

 a lecture upon the respiration and circulation of fishes, which 

 he illustrated by drawings, preparations and dissections. A 

 committee was appointed to prepare a system of classification, 

 by which the various departments of the sciences may be 

 assigned to the members according to some fixed order. 



January 28. — The following system of classification, was 

 reported by the committee, charged with that duty at the last 

 meeting, and adopted, and the members were subsequently 

 assigned to each class respectively, by the president. It is 

 expected that every member will enroll himself under one class 

 at least, but he may co-operate with as many of the classes as 

 inclination will permit. Each class is considered a standing 

 committee, upon the particular department of natural science, 

 whose title it bears, and all communications and specimens 

 submitted to the Academy are to be referred to that class, 

 having particular cognizance of the subject. 



1st Class. — Mathematics, astronomy and physics, the latter 

 including natural philosophy and mechanics. 



2d Class. — Chemistry. 



3d Class. — Mineralogy and geology, including physical 

 geography and the history and classification of fossil remains.
