cuit. In these comparisons Prof. Looniis had charge of the observations in New York. In 18(50 he became professor of natural philosophy and astronomy in Yale, and afterward devoted a large part of his time to original researches, the most im- portant of which were a series of articles published in the " American Journal of Science," under the title of " Contributions to Meteorology."' He was engaged in revising these papers, and arranging the different topics in systematic order, at the same time subjecting each principle to more rigid inves- tigation by comparison with the numerous obser- vations which have recently been published in the United States or abroad. These revised contri- butions, when completed, will present a very full discussion of the principles of dynamic meteor- ology. The titles of his scientific papers exceed 100 in number, and they have appeared both in this country and abroad in journals and in transac- tions of societies of which he was a member. In 1854 he received the degree of LL. D. from the University of the city of New York. Prof. Loomis was a member of scientific societies in the United States and in Europe, and in 1873 was elected to the National academy of sciences. Besides "On Certain Storms in Europe and America" (Washington, 1860), forming part of one of the Smithsonian contributions, he published " Plane and Spherical Trigonometry " (New York, 1848) ; "Progress of Astronomy " (1850 and 1856) ; " Ana- lytical Geometry and Calculus" and " Elements of Algebra " (1851) : " Elements of Geometry and Con- ic Sections " (1851 and 1871) ; " Tables of Loga- rithms " (1855) ; " Natural Philosophy " (1858) ; "Practical Astronomy" (1855 and. 1865); "Ele- ments of Arithmetic " (1863) ; " Treatise on Meteor- ology " (1868) ; " Elements of Astronomy " (1869) ; and "The Descendants of Joseph Loomis " (1870). LOOJttlS, Gustavus, soldier, b. in Thetford, Vt., 23 Sept., 1789; d. in Stratford, Conn., 5 March, 1872. He was graduated at the U. S. military academy in 1811, and assigned to the artillery.
