Aga iz, JzAN Louis RopoLPaE, the greatest of last century, was born at Motier, the Lake of Morat, in Switzerland, May 28th, where his father was pastor, his mother being daughter of a physician. As a boy he kept of all kinds, including fish. He was educated the gymuasium at Bienne, the academy at Lauthe medical school at Zurich, and at the of Heidelberg and Munich. At Heidelhe had Tiedemann, the anatomist, Leuckart, zoologist, and Bronn, the palzontologist, as his and Schimper and Braun, whose sister, afterwards became his first wife, as fellow and at Munich he lodged with Dollinger, embryologist, and attended lectures by Martius, and Oken. In 1829 Aga iz took his as Doctor of Philosophy at Erlangen, and 1880 that of Doctor of Medicine at Munich, not wishing to practise. He was entrusted Martius with the description of the fishes during the Brazilian voyage, the public a of which served as an introduction to Cuvier Humboldt on his visiting Paris in 1831. Here attended Cuvier’s last lectures, and imbibed his and anti-evolutionary opinions, real so from him all his notes and drawings to fo il fish. In 1832 he became Profe or Natural History at the newly organised Lyceum Neuchatel, a chair which he retained until 1846 this period he produced his chief work, Recherches sur les Poi ons Fo iles, in five with 311 plates, describing 20,000 spec i belonging to 1,700 species, contained in of the chief museums of Europe. In this he uses the scales as a basis of cla ification, the order of ‘“Ganoids,” and points the correspondence between the development of individual fish and ‘the succe ion of types of in geological time. During the proof this work he became a member of the Academy of Sciences and of the Royal visiting England in 1834, 1835, and 1840. 1836 he adopted Char pen tier’s views as to the greater extension of the glaciers of the and subsequently propounded the theory of a Period (q.v.), converting Buck land and to his views, as published in his Etudes sur Glaciers (1840) and Systéme Glaciaire (1846), showing glacial action to have occurred in Wales, and the Lake District. With the of Desor he completed, in 1842, his Monod'Echinodermes Vivans et Fo iles, and in with that of Karl Vogt, his Freshwater Fishes Central Europe. In 1846, with the a istance many other naturalists, he i ued his Vomen- Zooloyicus, which was supplemented in 1848 the Bibliographia Zoologia and Geologia. In Aga iz went to America, originally on a lecturing tour, but, as it proved, for the of his Fite He aroused a remarkable. for scientific research; a chair was for him at Harvard; and government were placed at his disposal for coast 4 Agave. dredging. In 1857 he i ued the first volume of his Contributions to the Natural History of the United States, containing the celebrated A ay on Cla ification, his last great work. The Museum of Comparative Anatomy at Harvard, established in 1859, now became the chief object of his life. In 1865 he made a journey in search of health and specimens to Brazil, Sr hee by his second wife (née Cary), and in 1871 he made a cruise right round South America, in the Ha ler. On his return, Mr. John Anderson presented him with Penikese Island for a school of marine zoology, and he had just succe fully launched this, his final idea, when his life of unremitting scientific toil ended peacefully at Cambridge, Ma ., 14th’ December, 1873.
