386 PROCEEDINGS OF THE CALIFORNIA 



Mr. Bolander presented a paper by Mr. Lesquereux, entitled 

 " A Catalogue of the species of Mosses found up to the present time 

 on the Northwest coast of the United States of America, and espec- 

 ially in California," which was referred to the Publication Com- 

 mittee and ordered printed in the Memoirs of the Academy. 



Professor Whitney exhibited several of the maps in preparation 

 at the office of the State Geological Survey, and gave a somewhat 

 detailed account of the operation of the survey during the year 

 1866 and 1867, and of the progress in the publication department 

 of that work. The statement made was in the main identical with 

 that contained in the biennial letter of the State Geologist to the 

 Governor, published by order of the Legislature then in session. 



Dr. H. Gibbons exhibited a piece of pork erroneously supposed 

 to contain trichinae ; he believed the entozoa in question were really 

 Cysticerci. They have the appearance of soaked peas, and are 

 not injurious when cooked. 



Mr. R. L. Harris mentioned the fact that the railroad surveys 

 conducted by himself, for connecting Vallejo and Sacramento, indi- 

 cated that the latter place was not so much above the sea level as 

 had generally been assumed from barometrical observations, and 

 he believed that the top of the present levee at Sacramento was 

 about twenty-one feet above mean high tide at Vallejo, instead of 

 fifty-six, as previously supposed. If this was true, then the low- 

 lands in the vicinity of Sacramento were in fact, only about one 

 and a half feet above the sea level. The surveys of the coming 

 season would probably enable him to fix this important point with 

 accuracy. 



Dr. Gibbons suggested that if the tule lands in the Sacramento 

 and San Joaquin Valleys were permitted to undergo the natural 

 processes of growth and decay, instead of being annually burned 

 over, the land in question might in time become sufficiently elevated 

 to be inhabited. 



Mr. Goodale, who had recently visited Russian America, exhib- 

 ited a number of implements and weapons of the natives of that 

 region, and gave an account of their use. He also remarked on 

 some of the topographical and geological features of that country.
