CoPEMAN (S. M.). Note on a successful method for the extermination 

 of Vermin infecting Troops. — Brit. Med. Jl., London, 6th February 

 1915, pp. 247-248. 



Troops in camp in the South of England were found to be infested 

 with vermm, and measures had to be devised under practically field- 

 service conditions for facilitating cleanliness, including arrangements 

 for hot baths. The men found to be infested were directed to take a 

 hot bath, dry themselves and then lather their bodies with cresol soap 

 solution (Jeyes' fluid 1| oz., soft soap 1| lb., water 10 gals.) and allow 

 the lather to dry on ; the shirts were washed in the same mixture 

 in boiling water ; the tmiics and trousers were turned inside out and 

 the lather rubbed well into the seams and allowed to dry on. Blankets 

 were treated by first soaking in cresol soap solution and subsequently 

 washing in the ordinary way. The method both for the soldiers and 

 their clothing has been found to be thoroughly satisfactory.

Dr. Shipley quotes C. P. Lounsbury as to the supply of the troops 

 in South Africa by the Government with sulphur sown into small 

 bags of thin cahco and secured to the underclothing next to the skin, 

 as a preventive against lice. The bags are about 2 inches square, and 

 are generally worn one on the trunk and one against each leg. Dr. 

 H. H. Tomkins is quoted as saying that sulphur well rubbed into the 

 underclothmg was perfectly successful in preventing lice from getting 

 under plaster of Paris jackets in the Children's iufirmary at Liverpool. 

 Further, Mr. B. Harman, at the No. 2 General Hospital at Pretoria 

 during the Boer war, finding that he was infested with lice, and failing 

 to obtain insect powder, tried dusting his clothes and bedding with 

 sulphur, with the best results ; and on board ship he fomid the same 

 method equally efficacious against cockroaches.

 through Mosquitoes that convey Malaria. — Southern Med. Jl, 

 Mobile, Ala., viii, no. 3, 1st March 1915, pp. 184-194, 2 figs. 



Anopheles quadrimaculatns was the species concerned in conveying 

 malaria in 1914 in the vicinity of Mound, Louisiana, the other two 

 species fomid, A. 'punctipennis and A. crucians, only occurring in 

 very small numbers. The records of breeding places show that A. 

 quadrimacidatus is partially domestic in its habits. It was taken 

 from water stored in cisterns and in barrels, from water in surface 

 wells and from troughs used for watering stock. Greater numbers 

 were found in the bayous, seasonal sloughs, pools in the woods and 

 holes from uprooted trees. In open collections of water of a permanent 

 character, having margins free from vegetation or rubbish, the top 

 minnows and predaceous aquatic insects were very effective in 

 controlling the larvae of Anopheles and other mosquitos.
