XX PROCEEDINGS OF THE GEOLOGICAL SOCIETY. 
Alcide d’Orbigny, in 1861, he was nominated to fill the chair of 
paleontology in the Muséum d’Histoire Naturelle in Paris. 
The substance of four of the courses of lectures which M. d’Archiae 
delivered in his new capacity has been published in three velumes, 
under the title of ‘Cours de Paléontologie Stratigraphique.’ The 
first volume contains a précis of the history of paleontology ; the 
second is devoted to a general view of biology, as an introduction 
to paleontology ; 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, embody- 
ing 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 Paleontology of France, 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. 
JosppH Brrre Juxes, Fellow of the Royal Society, was born in 
Birmingham on fhe 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, pro- 
ceeding 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 in- 
vestigation 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 Sur- 
veyor 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 parsi- 
mony of the Colonial Legislature refused to grant the money requi- 
site to pay for the ‘ Report,’ and it would have been lost to science 
if the Governor, Sir John Harvey, whose name ought to be grate- 
fully recollected by geologists, had not taken the expense upon him- 
self. The “ Report,” forms a part of the ‘ Excursions in Newfound- 
-land, published in 1842. In the latter year appeared Potter’s 
‘ History of Charnwood Forest,’ which contains an able and inter-
