In Professor Starkweather's death, Yale mourns the loss of one who died at the very thresholdof a brilliant career which promised to be full of honor and usefulness. He received the degree of Mechanical Engineer at Yale in 1894, and the degree of Doctor of Philosophy at the same university in 1898. He was a member of Calvary Baptist church, New Haven, Conn., and also a member of the Republican party. He was Instructor and Assistant Pro- fessor of Mechanical Engineering from graduation until his death. He was unmarried. GEORGE FETTER STICKNEY was born january 24, 1869, in St. Paul, Minn. He prepared at St. Iohn's Military Academy, Ossining, N. Y., and Hillhouse High School, New Haven, Conn., entering college in the begin- ning of Freshman year. He took the Civil Engineering course. Wliile in college he was a member of A. CD. society. His father, Amos Stickney CWest Point BS., 18633, an officer in the Engineers Corps, U. S. Army, was born in St. Louis, Mo. He has also been President of the Missouri River Commission, President of the Mississippi River Com- mission, President of the Board of Engineers, President of the New York Harbor Line Board, Division Engineer, Eastern Division, and Engineer officer of Atlantic Division. His mother, whose maiden name was Virginia Eetter, was born April 22, 1848, in Louisville, Ky. He married, October 3, 1894, in Frankfort, Ky., Kath- erine Halloran CNazareth Academy, Ky., 18895, daughter of Thomas Halloran, an engineer and contractor, and a graduate of Dublin University. They have one daughter, Josephine, born july 30, 1895. Stickney became a lock designer with the Barge Canal, New York, October 12, 1905. He was Captain of the Third U. S. V. Engineers in the Spanish-American War.

BIOGRAPI-11135. 109 mination of the latent heat of steam may be materially improved by taking account of this circumstance. This has an important bearing on the subject of the specific volume of steam, since by far the most accurate determinations of this quantity are those derived by thermodynamic principles from the latent heat and the pressure of saturated vapor. ln fact, Mr. Starkweather shows by a careful analysis of the experiments of various physicists for the direct deter- mination of this quantity that these experiments really add nothing to what we get by the indirect method combined with the theoretical value derived from the molecular formula of steam. In the second paper, 'The Thermodynamic Relations for Steamf the formulae are discussed which others have used. Mr. Starkweather then gives certain formulae of his own. In particular for the relation between pressure volume and temperature, he gives a modification of Clausius' form of the equation of Van der 'Waals and uses this as a foundation for the derivation of equations between other variables. From these formulae he calculates tables of the principal quantities relating to saturated steam which may doubtless claim a considerably higher degree of accuracy than the usually received values. Professor Starkweathers last paper, 'Non Quaternion Number-Systems Containing No Skew Unitsf A1716I'fCG7Z foimial of Matlirmm-tics, vol. xxi, is one of the most import- ant contributions to the theory of hyper-complex number- systems that has been made in recent years. These papers all give evidence of marked originality and breadth of treatment. It is indeed remarkable for one person to excel in branches so remote from one another. They tell too plainly to need further comment the breadth of Professor Starkweathens scientific interests. Another characteristic trait of his mind was remarkable quickness of perception joined with a love for the more philosophic and fundamental parts of a theory. He grasped not only the details, but was instinctively attracted toward the deep lying

He prepared at St. Paul's School, Concord, N. H., and entered college in Fresh- man year, pursuing the Mechanical Engineering course. His father, Carlos Merril Sturtevant, was born May 1, 1842, in Russel, O. He now resides in Cleveland, O. He is a retired member of the firm of Sturtevant Lumber Co. His mother, whose maiden name was Harriet Abbey Dickinson, was born in Lowell, Mass. She died in Cleve- land, O. He has two sisters: Ida Belle and Elizabeth Mary. He is another of the unmarried part of the Class. Sturtevant became a part owner, july 1, 1905, in the Young Bonanza Mining Co. He is a member of the Episcopal church, the Masonic order, and the Republican party. Following is the history of his life since gradua- tion: VV ent West in the fall of 1891 with the Union Pacitic R.

He went to the Northport Smelter at Northport, WVash., in 1898 as metallurgical clerk. 1900 took him to Butte, Mont., as metallurgical clerk in F. A. Heinze's Smelter, which position he held for only a short time, when he went to the Michigan College of Mines at Houghton, Mich., where he took a special course in metallurgy and surveying. He came back to Butte in 1901, and was appointed Assistant Superintendent of F. A. Heinze's Smelter, which position he held until December, 1903, when he went to Utah as Superintendent of the x
