 proportions of the head and face, and the characters of 

 the teeth were very different, that Chimpanzee, like 

 Orang, is a generic term, and includes several species. 

 It does not seem possible to refer all these to a single 

 species of Chimpanzee, and that one the Troglodytes niger. 



Dr. Warren alluded to the fact, which at the present 

 time is worthy of mention, that the Gorilla was first 

 introduced to the scientific world by Drs. Savage and 

 Wyman, in the pages of the Journal of the Boston Soci- 

 ety of Natural History ; and that even the specimen in 

 the Jardin des Plantes of Paris was obtained by the 

 instrumentality of those who were making collections 

 for this Society.

 Newfoundland ; it seemed identical with the Paradox- 

 ides Harlani, from Braintree, Mass. He said that this 

 formation could be followed, though in an interrupted 

 line, from Braintree to Newfoundland. As the people 

 of Newfoundland are now directing their attention to 

 mining, it is probable that the consequent exploration of 

 the country will throw more light upon this interesting 

 question. 



He gave an account of the original specimen of P. 

 Harlani, which was said to have been stolen from Cam- 

 bridge, sold to the old Columbian Museum in Boston, 

 and thence purchased by Mi*. Alger, in whose possession

Dr. Jackson also presented some of the berries of the 

 plant (Rhus succedaneum) which produces the so-called 

 Japanese Wax, and a specimen of the wax thence ob-

On boiling the berries in water, the wax rises to the surface ; 

 it is a concrete volatile oil rather than a wax ; it exists under the
