The French Academy of Sciences and French Science have lost two of their most distinguished representatives in the deaths of Joseph Bertrand and of Alphonse Milne-Edwards. Bertrand was born in 1823, and was somewhat of a prodigy when a boy, having published a paper on the theory of electricity when but sixteen years old, and being the author of numerous mathematical papers before he was twenty-one. His original contributions to mathematics and mathematical physics are of great importance, and he was the author of standard works on algebra, on arithmetic and on the calculus. As permanent secretary of the Paris Academy of Sciences he was continually engaged in administrative work, preparing obituary notices, acting as judge in the annual awards of its prizes, etc. He also contributed a large number of biographies and other articles to non-technical journals. Milne-Edwards, born in 1835, was a son of the eminent zoölogist, Henri Milne-Edwards, and the grandson of Bryan Edwards, the historian and member of the British Parliament. Milne-Edwards published important researches in paleontology and in zoölogy, especially in relation to birds, and was at the time of his death professor of zoölogy at Paris and director of the Jardin des Plantes. * * * * * In the deaths of the Duke of Argyll and Prof. St. George Mivart, Great Britain loses two men of a type more common there than in the United States. Argyll was a man of great wealth, whose interests in science were only secondary, but who did much directly and indirectly for its advancement. His work, ‘The Reign of Law,’ published some twenty-five years ago, has been widely read, and he is the author of many books and articles concerned with the natural sciences. Mivart, although trained as a barrister, became perhaps a professional man of science, but he never occupied a regular university position. He published numerous contributions to comparative anatomy and zoölogy, but is perhaps best known for books and articles on general scientific subjects. Just before his death, it will be remembered, he was excommunicated from the Roman Catholic Church owing to articles which were supposed not to be in conformity with its tenets. Both Argyll and Mivart represented an attitude towards the doctrine of evolution which may be regarded as now practically extinct. * * * * *
