Several cases of internal myiasis, chiefly in the nasal cavities, due 

 to infestation by Cochliomyia {Chrysomyia) macellaria (screw-worm 

 fly) are described. The larvae were successfully expelled by applying 

 a continuous current of electricity or by inhalations of chloroform.

In this portable apparatus, invented by Surgeon-Major Lochon, 

 the rapid combustion of a large quantity of sulphur is attained by 

 very simple means. Usually only 20-25 grms. of sulphur per cubic 

 metre can be burned in a room or other closed space, as the gas SO2 

 does not support combustion. With the Lochon burner 100-120 grms. 

 per cubic metre are vaporised in about half an hour. This is due to 

 the strong draught resvilting from the arrangement of combustion 

 trays one over the other and to the use of an oxidising powder of which 

 6 parts by weight are used per 100 of sulphur. When burning, this 

 powder produces oxygen which partly combines with the sulphurous 

 anhydride (SO.,) and thus produces sulphuric anhydride (SO3) to the 

 amount of 0'4 per cent, of the total gases emitted. The mixture of 

 SO2 and SO3 has a very powerful microbicide and parasiticide action 

 and does not produce the deterioration and discolouration that SO., 

 alone may give rise to. The apparatus can also be used for vaporising 

 formol. It is fully described and illustrated, and notes on working 

 are given. All insects were killed in half an hour by burning 50 grms. 

 of sulphur and 3 grms. of oxidising powder per cubic metre of space.

 — Jl. R. Sanit. Inst., London, xl, no. 1, 1919, pp. 53-60. 

 [Received 4th November 1919.] 



Not including the Sarcopsyllids, there are about 34 species of fleas 

 belonging to 15 genera that have been found on rats, although other 

 animals are in some cas&s their normal hosts. A hst of these species 

 is given together with their normal hosts and the countries in which 

 they occur. Of these XenopsijUa cheopis, Cerafophylhs fasciatus, 

 PygiopsyUa ahalae, Hoplopsylhis anonialus, Leptopsylla muscuU, 

 •Ctenocephahis canis and Pidex irritans are known to bite man and
