9. Observations and Experiments for excluding the House and 

 other Flies from Apartments by means of Nets. By the Rev. 

 E. Stanley, now Lord Bishop of Norwich. 



In this paper the author merely states that he had employed 

 the nets of worsted, thread, &c. as recommended in a former 

 paper by Mr. Spence, for the purpose of excluding flies, and 

 has found them completely efficacious. 



10. Observations on Succinic Insects. By the Rev. F. W. Hope, 

 M.A. F.R. S. &c. Part II. Gums and Resins. 



In commerce the term gum is improperly applied to Copal 

 and Anime, both of which are resins. The gums principally 

 imported into England are those of Arabia and Senegal ; none 

 of them appear to have been hitherto found containing insects. 

 Resins are insoluble in water, but are generally soluble in 

 alcohol, especially if assisted with heat. Copal appears to be 

 a Mexican word for gum, and is applied alike to gums and 

 resins ; it is said to come from South America, and also from 

 India (which I doubt) ; and the tree producing it in New 

 Spain to be Hymenal Courharil. It is found in rounded 

 lumps, and is said to contain insects, but I have hitherto found 

 none. Anime is a resinous substance, which exudes from the 

 Vateria Indica, a gigantic tree of Malabar, as also from some 

 unascertained tree in central India, and from the Trachylobium 

 Gcertnerianum^ a native of Madagascar. The term Anime was 

 first applied by the Portuguese to the gum of a species of
