accident in early life from active pursuits he turned his 

 attention to science, and in 1867 carried out some important 

 original work, in recognition of which he was that year made 

 a Fellow of the Royal Society. In 1865 he settled at 

 Haslemere, where he died on the 25th September, 1905. Mr. 

 Buckton was the author of valuable entomological works. His 

 monograph of the " British Aphides," in four volumes (1876- 

 1883), was followed in 1890 by his illustrated monograph of 

 the " British Cicadae or Tettigidse," and afterwards by the 

 "Natural History of Eristalis tenax," and by various pub- 

 lished papers. Most of the plates in these works were drawn 

 and in some cases lithographed by himself. Mr. Buckton was 

 a member of the Linnean Society, the Chemical Society, 

 and of several foreign scientific societies, many of the meetings 

 of which he attended, and by the members of which, as well 

 as his numerous private friends, his kindly and courteous 

 presence will be missed. 



I ask leave this evening to bring under your notice a 

 subject on which entomologists have thrown some light, but 

 which by common consent stands in need of much more ; to 

 call attention to some of the effects on living things of that 

 chief element in climate, temperature, and to the remarkable 

 limitations imposed on those effects by the nature of the living 

 thing operated on, these two opposing forces giving rise to a 

 state of conflict between the outside power and the organism. 



General operation of temperature. 



The general effect on a growing organism of an augmented 

 temperature, within the limits of healthy vitality, and 

 associated with other wholesome conditions, is well recognized, 

 as promoting physiological activity, heightening energy and 

 accelerating development. The whole practice of "forcing," 

 as applied in many industries, by florists, market-gardeners, 

 chicken-farmers, and others, is founded on this principle, and 

 entomologists every day come upon illustrations of it.
