time nor the technical knowledge necessary for the perusal of 

 strictly scientific works we heartily recommend it. To college- 

 students and scholars in high schools also, who do not wish to go 

 out into life unacquainted with the grandest generalization of our 

 day, we also advise its perusal. And all who wish to make 

 acquaintance with the fundamental facts of evolution, whether 

 called by the name of Darwin or any other, and who are not too 

 blinded by prejudice to read and reason fail ly , we commend this 

 little work, the composition of a period of enforced seclusion from 

 active life on the part of one of its authors. 



VII. The Late J. George Jeffreys, M.D., F.K.S. 



By Sir J. W. Dawson. 



A late British mail brings the intelligence of the death of 

 this eminent naturalist, probably the oldest British zoologist 

 next to Owen, and at the time of his decease generally recognised 

 as the most eminent conchologist in Great Britain. Dr. Jeffreys 

 was born at Swansea, in January, 1809. He was a zealous 

 collector of shells from his youth, and was one of the earliest 

 scientific dredgers on the shores of Great Britain. He took a 

 leading part in connection with some of the sea-expeditions of 

 the English, and French governments, and at the time of his 

 death was busily engaged in the investigation of the mollusca 

 dredged by the Porcupine. Besides his great work in British 

 conchology, he was the author of a large number of memoirs in 

 the Transactions of the Koyal, Linnsean and other Societies. He 

 was a man of broad general views, as well as of attention to de- 

 tails, and was especially interested in the relation of the subject 

 to physical geography and the history of genera and species in 

 geologic time. In connection with this he took much inter- 

 est in the discoveries recently made in this country, and some of 

 his most recent papers had reference to the relations of European 

 and American mollusca. He was in correspondence with many 

 of the leading workers in modern and pleistocene mollusks in 

 the United States and Canada. When in Canada some years 

 ago he was the guest of Sir William Logan, and spent much time 

 in inspecting the collections of Dr. Carpenter at McGill College, 

 and in examining the dredgings of Mr. Whiteaves in the collections
