Dr. Henrj Gibbons then presented a communication from J. 

 M. Upham, of Rio Vista, which was read. Mr. Upham stated 

 that the remains of several Indians had been exhumed near that 

 place. One, the body of a woman, Avas found buried in a sitting 

 posture, while the men were lying on their sides, in a cramped-up 

 position. The skull of the woman had been secured by a gen- 

 tleman and brought to this city. All of the bones were gathered 

 up by the Chinamen working at the place where they Avere found, 

 and burned. Mr. Upham mentioned the reclamation of Sherman 

 Island, where forty-seven miles of levee, five feet in height, had 

 been built, at a cost of <|80,000. He invited a committee from the 

 Academy to visit that locality, and thought they would be able to 

 collect much valuable information. 



The Secretary was directed to acknowledge the invitation with 

 the thanks of the Academy. 



The members then entered into a very interesting discussion in 



Peoc. Gal. Acad. Sci., Vol. IV.— 5 Feb. 1870.
