mosquitos were caught in the year, of which 251,332 were Taer.io- 

 rhjnchus (Mansonia) titillans ; of Anophelines, Anopheles albimanus 

 was far the most numerous, the others being, in order of frequency, 

 A. tarsmiaculatus, A. malefactor, A. jjseudopunctipennis, A. apicimactda, 

 and A. argyritarsis. 



Hand-catching has not only proved economical, practical, and 

 successful in the considerable reduction of malaria cases, but also, 

 in its results, acts to a certain extent as an index to the breeding 

 places. In the event particularly of Stegomyia fasciata {Aedes calopiis) 

 making its appearance in the catch, it is generally taken as an indi- 

 cation that it is breeding in the immediate vicinity, as this species 

 seldom breeds far from human habitations. Steps are then taken 

 to locate the breeding place, which usually proves to be some old tin 

 can or similar receptacle, and when found is easily abolished.

These papers give an account of various outbreaks of tick fever 

 among Indian troops and their officers in East Persia. The men 

 were attacked by two species of tick, Argas persicus and OrnitJiodorxs 

 lahorensis, when occupying Persian serais. The majority of the cases 

 were absolutely free from lice. Some of the men who were bitten by 

 ticks did not develop the disease. It seems probable that the disease 

 is developed on the eighth day after it is transmitted ; at any rate 

 the incubation period is from one to twelve days. 



Spirochaetes are few and difficult to find, in contrast to what occurs 

 in the recurrent fever carried by lice. In this the disease resembles 

 African tick fever, but the spirochaetes of the two diseases are some- 

 what difterent in form. In Persia as in Africa the local natives are 

 immune to the disease, but strangers are susceptible.

 War. — Jl. R.A.M.C., London, xxxv, no. 3, September 1920, 

 pp. 228-232, 2 plans. 

 A description is given of the combined bathroom and delousing 

 apparatus used in the German Army for troops when reheved from 

 the line. The heating for both bathroom and disinfector came from 

 the same furnace ; the men passed through the former parallel with 

 their clothes passing through the latter, receiving their clothes clean 

 on the other side. The clothing was left in the disinfector at a tem- 

 perature of 100° C. dry heat for one hour. Where convenient it was 

 found that baking the clothes for two hours at 80° C. gave better results. 

 Other methods of treatment mentioned are hydrocyanic acid gas, 

 sulphur dioxide combined with dry heat, and steam wagons, and a plan 

 is eiven of a bath-house and disinfector suitable for barracks. As a 

 prophylactic, crude naphthaline was issued at first, but irritated the 

 skin too much. A half and half mixture of powdered talc and naph- 

 thahne was afterwards issued, but this was also too strong and was 

 never in general use. Treatment for scabies consisted of baths and 

 an ointment of balsam of Peru.
