LINNEAN SOCIETY OF LONDON. IxXXV : y^ 



Mr. Denny was also Secretary to the "West-Riding Geological and ^ 

 Polytechnic Society ; and he had just prepared for the press the Ee- 

 port of the Transactions of this body before his last illness. To ^a^ 

 two societies with which he was officially connected he frequently 

 contributed papers. He was an entomologist of high standing, and 

 in this branch of science published two works which have long been 

 recognized as authorities. His first work, the ' Monographia Psela- 

 phidarum et Scydmsenidarum Britanniae ' (1825), was dedicated to 

 the famous naturalist Dr. Kirby, who was a private friend of the 

 author, and was published at Norwich not long before Mr. Denny's 

 removal to Leeds. It was the first treatise upon the Pselaphidae 

 and Scydmsenidae which had appeared in this country. In the 

 publication of his second and more important work, he was assisted 

 by the British Association. The volume was entitled " Monographia 

 Anoplurorum Britanniae — an essay on the species of parasitic insects 

 belonging to the ' Anoplura ' of Leach, with the modern definitions and 

 the genera according to the views of Leach, Nitzsch, and Burmeister " 

 (1842). In the progress of the work the number of known species 

 increased so rapidly as to preclude the publication of the book at 

 the price announced in the prospectus. At the time when Mr. Denny 

 was engaged on the work, the British Association had its meeting at 

 Glasgow ; and upon the recommendation of Sir W. Jardine and Mr. 

 Selby, the sum of £50 was granted by the Association to assist in 

 furthering the knowledge of the British Anoplura. This sum was 

 placed at Mr. Denny's disposal, Sir "W. Jardine, Mr. Selby, Mr. W. 

 ZarreU, and Dr. Lankester being appointed trustees in connexion 

 with the grant ; and when the work was issued it was dedicated to 

 the two first-named gentlemen, and to Dr. R. K. Greville. Both the 

 above-mentioned works were illustrated by highly magnified figures 

 of the species described, the drawings having been executed with 

 taste by Mr. Denny himself. Mr. Denny was a corresponding mem- 

 ber of the Academy of Natural Sciences of Philadelphia, and of the 

 Syro-Egyptian Society of London. He was also an honorary mem- 

 ber of the Philosophical Society of Dickinson College, Carlisle 

 (Pennsylvania), and of the Yorkshire Philosophical Society. He was 

 elected an Associate of this Society on the 19th of December 1843, 

 and died at Leeds, on the 7th of March 1871, at the age of sixty- 

 eight. 



The Venerable William Hale Hale, M.A., Archdeacon of Lon- 

 don, and Master of the Charterhouse, was born on the 12th of 

 September, 1795. His father, who died while he was very young, 

 was a medical man. He became a ward of the late Mr. James
