Alcide d'Orbigny, in 1861, he was nominated to fill the chair of palæontology in the Muséum d'Histoire Naturelle in Paris.
The substance of four of the courses of lectures which M. d'Archiac delivered in his new capacity has been published in three volumes, under the title of 'Cours de Paléontologie Stratigraphique.' The first volume contains a précis of the history of palæontology; the second is devoted to a general view of biology, as an introduction to palæontology; while the third gives an account of the fauna of the Quaternary epoch. At this point the series of the 'Cours de Paléontologie' ceases; but, in 1866, a complete treatise, embodying M. d'Archiac's views on the totality of geological phenomena, entitled 'Géologie et Paléontologie' appeared.
The last work from M. d'Archiac's pen is the great Report on the Palæontology of Prance, which was published in 1868.
All who have known M. d'Archiac personally, speak in the warmest terms of the uprightness of his character, and of his keen sense of honour and independence. And it is lamentable to know that the pressure of petty cares so destroyed the balance of his sensitive and finely strung mind, that a few more years of patient endurance of such troubles appeared as little possible to him as any application for help to the many friends who were not only able, but would have been proud to serve him. The Vicomte d'Archiac was in his sixty-seventh year at the time of his death.
Joseph Beete Jukes, Fellow of the Royal Society, was born in Birmingham on the 18th of October 1811, and was educated partly at the Merchant Taylor's School in Wolverhampton, and partly at King Edward's School in Birmingham. At the latter school he gained an exhibition, which took him to Cambridge, where he entered St. John's College in 1830, and took his B.A. degree in 1836, proceeding to his M.A. in 1841.
The genial enthusiasm and large knowledge of the Woodwardian Professor of Geology, then in his vigorous prime, worked upon Mr. Jukes, as they seem to have affected all men who came within the range of their influence, and determined him to make geological investigation the vocation of his life. Immediately after leaving Cambridge Mr. Jukes became a Fellow of this Society, and, as we all know, he was for four and twenty years one of its most active and valued members.
In 1839 Mr. Jukes was appointed to the office of Geological Surveyor of Newfoundland. He remained for two years in this capacity, and executed the survey: as well as the means at his disposal would permit. When, however, the work was done, the capricious parsimony of the Colonial Legislature refused to grant the money requisite to pay for the 'Report,' and it would have been lost to science if the Governor, Sir John Harvey, whose name ought to be gratefully recollected by geologists, had not taken the expense upon himself. The "Report," forms a part of the 'Excursions in Newfoundland,' published in 1842. In the latter year appeared Potter's 'History of Charnwood Forest,' which contains an able and inter-
