These Bpecimens were spawned on the 4th of November.

 defined. The light used was direct and not reflected as in 

 the former instance.

Cleveland, December 12, 1856. 



The Academy met, according to adjournment, in the 

 room of Dr. Garlick, the Doctor in the chair. 



The Academy resumed the examination of the young of 

 Salmo tontinalis. Living specimens, only twelve hours 

 hatched, were placed under the microscope. The circula- 

 tion of the blood, both arterial and venous, was observed 

 to the extremities of ramification ; the pulsations of the 

 heart, and the passage of the blood corpuscles through the 

 cavities of the ventricle and auricle, the arterial and the 

 return current through the great dorsal vessels, with the 

 peculiar cellular structure of the egg yolk that still 

 remained attached to the animal, were all distinctly visi- 

 ble in consequence of the transparency of the young fish. 

 Dr. Garlick had invented a small glass chamber sufficient 

 to contain the specimen in water, and yet deprive it suf- 

 ficiently of the power of motion to retain it in focus. These 

 exhibitions of Dr. Garlick's have been extremely interest- 

 ing and valuable to the members. 



Mr. Palmer exhibited specimens of Jatroplia manihot, 

 and its product, cassava flour. A drawing of a species of 

 lotus, Nymphea^ the seed of which is used for food; a 

 sample of Aqua ardiente^ the ardent spirit used by the 

 natives of Central and South America; dried specimens of 

 the Paraguay Tea, Ilex paraguaiensis^ and the utensils 

 made use of in manufacturing the infusion. Mr. Palmer
