Abstract
American Journal of Science and Arts, January, 1879.—Prof. Loomis's important paper in this number on storms on the Atlantic, &c., has been noticed elsewhere. Prof. Marsh (in an appendix) describes a new order of extinct reptiles (Sauranodonta) from the Jurassic formation of the Rocky Mountains; they closely resemble Ichthyosaurus (of which no remains have hitherto been found in America), but are without teeth. The same author continues his “Principal Characters of American Jurassic Dinosaurs.”—Prof. Greene, of Troy, New York, describes a paper dome constructed from his plans for an astronomical observatory. The paper covering is in sixteen equal sections, the framework of each section consisting of three ribs of pine meeting at the apex. There are also a circular sill at the base and two parallel semicircular arch girders spanning the dome (all of pine). The entire structure weighs about 4,000 lbs. The dome is supported on six 8-inch balls rolling between grooved iron tracks by direct pressure.—Mr. Edison describes his tasimeter as applied to measuring the heat of the stars and of the sun's corona.—Mr. Fontaine writes on the mesozoic strata of Virginia, and Mr. Holden on the brightness and stellar magnitude of the third Saturnian satellite.—A list of fifty species, of east coast fishes (many of them new to the fauna) is supplied by Messrs. Goode and Blan.—In the “Miscellaneous Intelligence” will be found the report of the committee appointed to consider the scientific surveys of the United States territories.
