Dr. Kellogg exhibited specimens of Thaspium cordatum, (Heart- 

 leaf Meadow Parsnip) a plant which has become somewhat known 

 in cases of chronic rheumatism, and which is common on this coast. 

 He remarked that it might be mistaken for Sanicula, (Sanicle) 

 or possibly for Conium maculatum (Poison Hemlock). 



Dr. Kellogg also presented specimens of a beautiful Alpine wil- 

 low-herb collected by Mr. Blanchard, of Brooklyn, Alameda County ; 

 it was found in the mountains west of Owen's Lake, near the 

 Kearsarge mines, at an altitude of 8,000 feet. He considered 

 it a variety of Epilobium obcorclatum, Gray. This plant is de- 

 scribed in the Proc. Am. Acad, of Arts and Sciences for May, 

 1865.

 fishes receive the nourishment necessary for its growth, has ever been pointed out. 

 It certainly differs from the three most common forms in which the embryo of 

 other animals is nourished, as there is nothing like a placenta by which they 

 can receive nourishment from the mother ; there is no supply of nutriment 

 surrounding the embryo, as in the case of most oviparous animals, nor is the 

 embryo brought into direct contact with the water, so as to derive nourishment 

 by absorption from the surrounding medium, as is the case in oviparous fishes 

 generally and in most of the lower forms of animal life. The young fish is
