of opinion that the Greek should take precedence of the Latin" ? To designate 

 species ! Why I thought that the rule (erroneously) claimed for Cuvier, and 

 first laid down by me, was that Greek should be used for genera ! There seems 

 to be a little confusion in this. But I look forward to the pleasure of seeing Mr. 

 Sweeting some time this summer, if all be well, when I will endeavour to set 

 him right on this and also on some other points. 



I remain, Sir, 



Faithfully yours,

PROCEEDINGS OF NATURAL HISTORY SOCIETIES. 



ZOOLOGICAL SOCIETY. 

 Aug. 22. — The ordinary meeting was held on Tuesday evening, Thomas Bell, 

 F.R.S., in the chair. — Mr. Owen exhibited the cranium of an Oran Outan from 

 Borneo, the dentition of which was intermediate with all the known species, and 

 which was the only example that had been seen in Europe. — Mr. Charlesworth 

 explained some facts on the structure of the Argonauts, particularly on the re- 

 production of certain parts of the shell. 



ROYAL SOCIETY. 



The following abstract of a paper " on the temperature of insects, and its 

 connexion with the functions of respiration and circulation," by Mr. George 

 Newport, is extracted from The Atkenceum of August 26. The account is of 

 such interest that we shall present it without curtailment. 



The author states at the commencement, that although it has long been 

 known that insects living in society, as the Bee and the Ant, maintain in their 

 habitations a temperature higher than that of the open air, the fact had never 

 yet been established that individual insects of every kind possess a more elevated 

 temperature than that of the medium in which they reside, and that in each 

 species the degree of elevation varies in the different stages of their existence. 

 He was first led to study the temperature of insects in consequence of the various 

 results which he had met with in some observations he had himself made, in the 

 autumn of 1832, on a species of wild Bee in its natural haunts, with a view to 

 ascertain, as had been suggested to him by Dr. Marshall Hall, the relation 

 between the temperature of these insects during their hybernation, and the 

 irritability of their muscular fibre : but the fact of the existence of a higher
