June 2, 1847. 

 The President in the Chair. 



Dr. Wyman exhibited Preparations of the Spines, from 

 the head of the Lophius Americanus, Cuv., showing their 

 peculiar mode of articulation, by means of two rings of 

 bone, resembling the links of a chain. The ring belonging 

 to the movable spine is in many specimens made up in part 

 of ligament. 



He exhibited a foetus of the Acanthias Americanus, 

 Storer, the vitelline sac being still suspended from the abdo- 

 men. He had taken a large number from the oviducts, and 

 found them nearly all in a corresponding stage of develop- 

 ment. There were none in an earlier stage, except a few 

 instances where the vitellus only existed in the duct, but the 

 process of development had not commenced. One speci- 

 men was captured swimming in the water, with the vitellus 

 still pendent. 



Dissections of the foetal and adult brain were also exhib- 

 ited, the former contrasting with the latter in having the 

 olfactory lobes in contact with the hemispheres, and these 

 last proportionally much smaller, more oval, and more 

 closely resembling the optic lobes in form and size.
