domesfica in transmission, it is proved that the bites of the former 

 are able to transmit it from an infected guinea pig to a healthy one, 

 and if the two applications are made within the space of an hour, 

 the animal will die in from five to nine days. Washings of the flies 

 in normal salt solution and of flies slightly crushed, when injected 

 subcutaneously, will produce similar results. House-flies allowed to 

 crawl and feed on the infected viscera of an animal dead of this disease, 

 and immediately transferred to a prepared conjunctiva, cause a severe 

 purulent conjunctivitis after 48 hours, ending in the death of the 

 animal. The faeces of house-flies similarly fed, suspended in salt 

 solution and introduced into the conjunctiva, will produce like results.

 in the Nose and Nasal Accessory Sinuses, — Jl. Amer. Med. Assoc, 

 Chicago, Ixiii, no. 26, 26th December 1914, pp. 2288-2289. 



Seventy-two and, later, forty Texas screw-worms [Chrysomyia 

 maceUaria] were removed from the nose of a farmer who had a long- 

 standing specific necrosis of the bones of the nose and accessory 

 sinuses which undoubtedly attracted the parent fly and furnished 

 favourable conditions for development of the larvae.

 1914, p. 416. 



A sickly calf is recorded to have been seriously infested by the 

 larvae of Lucilia sericata, Meig., a large number being discovered 

 embedded in the flesh, especially round the anus and base of the tail.

SarcopJiaga cooleyi, sp. n., is described and figured. It was ex- 

 tensively bred from decomposing fish and was also captured in privies, 

 and around garbage, especially if the latter contained fish. In one 

 experiment, in which two hundred larvae were used to determine the 

 length of the larval stages, no adult emerged, but numerous Chalcid 

 parasites were raised from the pupae.
