KDGAR EVERHART. The subject of this sketch was born April 8, 1854, in Stokes county, North Carolina. He was educated at Richmond, Va., Baltimore, Md., and Racine, Wis., at which latter place he re- ceived the Master ' s Degree. He then attended the School of Mines of New York city. After remaining there for some years, he went to Germany and attended lectures at the Universities of Wiesbaden and Freiburg. After receiving the degree of Doctor of Philosophy from the University of Freiburg, Dr. Bverhart re- turned to America, and taught Chemistry and the allied branches for five years in the Stevenson Institute, Hoboken, New York. He came to the University of Texas in 1884, where he has, for the last ten years, been Professor of Chemistry. The splendid chemical laboratory will always remain a monument to his untir- ing efforts to make the School of Chemistry what it is, the best in the South. Doctor Everhart has written many articles for American scien- tific journals that have attracted wide attention, and he has been elected a member of the German Chemical Society, the American Chemical Society, and American Society for the Advancement of Science. GEPRGE BRUCE HAI TED. The subject of this sketch was born in the State of New York. In 1875 he received the degree of Bachelor of Arts at Princeton. While at that institution, Dr. Halsted ranked high in all his classes, but especially did he distinguish himself in mathematics. On graduation, he won the fellowship in the above mentioned branch, besides gaining the intercollegiate prize. He next repaired to the School of Mines of New York City, where he devoted himself to mathematics and the natural sci- ences. Prof. Halsted next spent several years at the University of Berlin, Germany. Then followed his appointment as Fellow in Mathematics at the Johns-Hopkins University, Baltimore, where he studied two years, enjoying, at the same time, the instruction of that eminent mathematician, J. J. Sylvester, now professor in the University of Oxford. In 1879, Dr. Halsted received the de-

the same institution, which position he held until his removal to Texas University, in 1883. The war between the States having nearly emptied the Sem- inary of students, Dr. Dabney followed them, in May, 1861, into the army, first as Chaplain of the i8th Virginia Volunteers In- fantry, and in 1862, as Chief of Staff to General T.J. (Stonewall) Jackson, obtaining furloughs from the institution. In Septem- ber, 1862, he resigned his position on Jackson ' s staff, on account of protracted disease, camp tevers, etc. Partially recovering, he divided his time during the remainder of the war as Major of Home Guards and missionary preacher of the army of Lee. In May, 1883, he resigned from Union Theological Seminary on account of broken health, the result of old camp diseases and malaria, threatening pulmonary results. The same year he was elected Professor of Philosophy in the new University of Texas, and took part in its foundation, September, 1883, I June, 1890, his resignation was tendered to the Board of Regents, on account of loss of eyesight and impaired health. The Board, however, declined to accept the resignation, and made the following al- ternative offer, viz.: for him to retain full control of the School of Philosophy on half salary, with an adjunct professor to lighten his labors. This was accepted, and continues to the presnt time. Dr. Dabney ' s position has constrained him to frequent author- ship. First, in 1854, Memoir of Dr. Francis S. Sampson; in 1862, Defence of Virginia and the South, written for the Con- federate Government; in 1865, Life of Stonewall Jackson, by request of his widow; in 1866, Sacred Rhetoric; in 1871, Course of Systematic and Polemic Theology; second edition in 1879; in 1882, History of Sensualistic Philosophy of the i8th Century; in 1885, Inductive Logic, treatise for the Vic- toria Institute, London; 1890-93, Collected Discussions, three volumes, besides many review essays uncollected. Dr. Dabney received the title of D. D. from Hampden-Sidney College, and aftewards that of LL. D. from two colleges simul- taneously.

gree of Doctor of Philosophy, and then lectured for some time on logic and mathematics in the Johns-Hopkins. In 1879, he was called to Princeton, where he was appointed Instructor in Post-Graduate Mathematics, and taught quaternions, determinants, etc. In 1884, Dr. Halsted was appointed Professor of Pure and Ap- plied Mathematics in the University of Texas. Since this time he has been engaged in arduous work and has contributed many important articles to numerous scientific journals. Among these may be mentioned, Boole ' s Logical Method, Statement and Re- duction of Syllogism in ihQ Journal of Speculative Philosophy, and the Bibliography of Hyper-Space a7id No7i- Euclidian Geometry in the America i Journal of Matheinatics . But the most important labors of our professor are his text- books and scientific treatises. In 1885 appeared his Metrical Geometry. The book is especially cited in the last edition of the Kncyclopsedia Britannica, and the article, Mensuration borrows largely from his book on that subject. It has already been adopted as a text-book in several colleges, and an English edition has been issued by MacMillan and Company. In 1885 he published his ' ' Elements of Geometry. In 1892, appeared the Elementary Synthetic Geometry, the first book to reach its results without making any use of of congruent triangles. In addition to these works we must mention his Non-Euclidian Geometry, the first English translation of the work of Nicholaus Lobatschewsky; The Science Absolute of Space, the first English translation of the work of John Bolyai, and his Num- ber, Discrete and Continuous, an Exposition of the Origin and Growth of the Number C oncepts. Dr. Halsted has now ready for the press Pure Projective Geometry, which is followed by a treatise on Projective Metrics. ALEXANDER MACFARLANE. Dr. Macfarlane was educated at the University of Edinburgh, Scotland, where he obtained the degree of M. A., with highest honors in mathematics and physics, in 1875; B. Sc. in 1877, and D. Sc. in 1878. While a student he won, by competitive exam- inations in Greek, I atin, mathematics and physics, prizes and
