exclaimed, " I have ruptured a vessel of the heart," and died in about 

 half an hour. As a writer on Materia Medica Dr. Pereira stands 

 pre-eminent; of a large and powerful frame, and apparently endowed 

 with an iron constitution, he laboured for many years at the rate of 

 sixteen hours a day, and was most successful in his several capacities, 

 as a writer, a lecturer, and a medical practitioner. He became a 

 Fellow of the Linnean Society in 1828 and of the Royal Society in 

 1838 ; and died at his residence in Finsbury Square, in the 49th year 

 of his age. He was buried at Kensal Green, in the presence of a 

 numerous concourse of his friends and pupils. 



James Francis Stephens, Esq., was born at Shoreham in the county 

 of Sussex on the 16th of September 1792, and died in Foxley Road, 

 Kennington, on the 21st of last December, in the 61st year of his age. 

 His occupation, as a clerk in the Admiralty at Somerset House, con- 

 fined him to London ; but his leisure hours during his whole life 

 were zealously devoted to natural history, and especially to ento- 

 mology. His cabinet of British insects, a large portion of which 

 was collected by his own hands, was the most extensive and the 

 most complete that has ever been formed, and has been transferred 

 since his death to the British Museum. In the earlier part of his 

 life he edited some of the volumes, principally the Birds, of Dr. Shaw's 

 ' General Zoology,' and he gave, in the ' Transactions of the Cam- 

 bridge Philosophical Society,' " A Description of Chiasognathus 

 Grantii," a remarkably fine and singular beetle from the western 

 side of South America ; but with these exceptions his published 

 works relate entirely to British Entomology. The more important 

 of them are ' Illustrations of British Entomology,' Mandibulata, vols. 

 1-5, 1828-32; Haustellata, vols. 1-4, 1828-34; 'A Systematic 

 Catalogue of British Insects,' 8vo, Lond. 1829 ; ' The Nomenclature 

 of British Insects,' 12mo, Lond. 1829, and 8vo, Lond. 1833; 

 'A Manual of British Coleoptera,' 12mo, Lond. 1839; and 'A 

 List of the British Lepidopterous Insects in the Collection of 

 the British Museum,' 12mo, Lond. 1850. He became a Fellow 

 of the Linnean Society in 1815, and was elected President of the 

 Entomological Society in 1837. His "Address on the Fourth 

 Anniversary" of that Society was printed in 1838. In the forma- 

 tion of his cabinet of insects, he made frequent visits to all those 

 localities within a moderate distance of the metropolis where the 

 rarer species are to be found ; and he also purchased largely from 

 collectors and at sales. In this way he added to his collection a 

 great part of Marsham's cabinet of Coleoptera and of Haworth's Le-
