and humerus are of gigantic size and are indicative of the immense 

 strength of the arms, which are in relation not only to the arboreal life, 

 but, if the narratives of the natives be correct, to the immense bulk of 

 its body. 



The following are the more important of the specific characters enu- 

 merated by Dr. Wyman, by which the Enge-ena is distinguished from 

 the Enche-eco or chimpanzee. 



1. By its greater size. 



2. By the existence of large occipital and interparietal crests in 



the males. 



3. By the great strength and arched form of the zygomatic arches. 



5. By the form of the anterior and posterior nasal orifices. 



6. By the existence of an emargination on the posterior edge of the 

 hard palate. 



7. The incisive alveoli do not project beyond the line of the rest of 

 the face as in the chimpanzee and orangs. 



8. The ulna is much shorter than the humerus. 



9. The distance between the nasal orifice and the incisive alveoli is 

 less than in the chimpanzee. 



This valuable memoir is illustrated by four quarto plates.

 — Dr. Patterson, in the name of Prof. A. D. Bache, laid before the 

 Society, an abstract of a report, made by Mr. Sears C. Walker, of the 

 results of the telegraphic operations of the U. S. Coast Survey, made 

 by him on the 23d January last, between Washington and Philadelphia, 

 New York and Cambridge, Mass. A letter from Prof. Bache to Dr. 

 Patterson, accompanying the report, was read by Prof. Kendall. 



Washington, March 1, 1849. 



Dear Sir, — Will you please communicate to the American Philo- 

 sophical Society a brief abstract of a Report made to me on the 2Jst 

 ultimo, of the results of the telegraph operations of the U. S. Coast 

 Survey, made on the 23d of January last, between Washington, Phila- 

 delphia, New York and Cambridge, Mass., by Mr. Sears C. Walker, 

 assistant, having charge of the telegraph operations. 



The object in view was to test the practical working of the method 

 of imprinting the dates of star transits on a graduated clock register. 

 The three astronomical stations, selected for the occasion, were the 

 Philadelphia Observatory, under the direction of Prof. Kendall ; the 

 New York City station, in the private residence of Dr. L. M. Ruther- 

 ford, under Prof. E. Loomis ; and the Harvard Observatory, Cam- 

 bridge, under Prof. VVm. Cranch Bond. 



In conformity with the plan of his Report of December 15, 1849, 

 duplicate records were kept at the Washington Northern Telegraph 

 office, by Mr. Walker and myself. 



The astronomical clock was located at Philadelphia, and rated for 

 several days by Prof. Kendall. It contained two tilt-hammer electro- 

 tomes, one invented by Mr. J. J. Speed, Jr., of Ithaca, N. Y., in 1847
