V. Miscellaneous Scientific Intelligence. 



1. Bulletin of the California Academy of Sciences, January, 

 1887. — This number of the Bulletin contains among its papers: 

 G. P. Becker, on the Washoe Rocks ; V. E. L. Greene, Studies 

 in the Botany of California ; R. Smith, on Tetraodon setosus ; T. 

 L. Casey, Descriptive Notices of N. A. Coleoptera; Dr. G. 

 Davidson, on submarine valleys on the Pacific Coast; W. E. 

 Bryant, ornithology of Guadalupe Island ; G. Davidson, Early 

 Spanish Voyages of Discovery on the Coast of California. 



Guadalupe Island (29° 10' N., 118° 18' W.), is described as 

 about 5 miles wide, 15 miles long, volcanic and having a reported 

 height of 4523 feet. A ridge extends the whole length of the 

 island, having steep slopes to the west. In January and Decem- 

 ber of 1885, Mr. Bryant found the climate cool, frost often at 

 night, dense fogs frequent. The number of birds now known 

 from this island is thirty-six. "Four of the 'straggling species,' 

 Mountain Bluebird {Sialia artica), Varied Thrush (Uesperocichla 

 ncevia), Townsend's Sparrow (Passarella iliaca TJnalaschensis) , 

 Golden-crowned Sparrow (Zanotrichia coronata), are recorded 

 for the first time from so southern a latitude, while their presence 

 so far off shore is of scarcely less interest." The Humming bird, 

 Trochilus Anna, is one of the Guadalupe species. 



2. Technology Quarterly. Vol. I, No. 1. 96 pp. 8vo. — This 

 new scientific Quarterly, issued by the Massachusetts Institute 

 of Technology, Boston, promises to be a very valuable Journal. 

 It contains the results of work done by the students and officers 

 of the Institute of Technology, which is one of the largest and 

 best-equipped institutions of the kind in the country. The board 

 of Editors is chosen from its Senior and Junior Classes, among 

 whom Wm. S. Hadaway, Jr., is Editor-in-Chief. The subscription 

 price is two dollars a year. This first number contains thirteen 

 papers on technological, geological, chemical and other subjects. 



3. Meeting of the American Association for the Advancement 

 of Science, at New York, commencing Wednesday, Aug. 10. — The
