Hyg., London, x, no. 8, July 1917, pp. 199-206, 6 figs. [Received 



nth October 1917.] 

 A'arious fly-proof devices, planned for the use of soldiers and others 

 in the troisics, are described and illustrated. These include a fly-proof 

 verandah to the ordinary double-roof ridge tent and a mosquito net 

 made to fit the shape of the tent in place of the usual arrangement over 

 the camp-beds. As a protection from Glossina and other biting flies, a 

 helmet knitted of native string is described, which is similar in 

 appearance to a Crusader's headpiece of chain-mail, leaving only a 

 small opening for the features. A layer of coarse mosquito-netting is 

 sewn on the surface of the knitted string, so that a fly trying to bite 

 through it finds its proboscis too short to reach the skin. A large felt 

 or terai hat can be worn over the helmet. Fingerless gloves with 

 khaki gauntlets, made in the same way, may be used to protect the 

 hands. For the protection of troops on active service in malarious 

 countries from mosquitos, much can be done by a wise selection of 

 camping grounds. 



Robertson (J.). Flies and Stable IAUqv.— Public Health, London, 

 XXX, no. 12. September 1917, pp. 245-246. 

 The author describes experiments made during the past three 

 summers to ascertain the variety of stable litter which is least attractive 

 to flies and which least facilitates their breeding. In 1917, fresh straw, 

 fresh sawdust and shavings, and fresh peat-litter were used. No flies 

 bred out of the peat-manure, while there were a few (18) from the 

 sawdust and shavings and 244 from the straw manure.

 African Coast fever is still the most important problem with which 

 the Veterinary Division has to deal. Records are given from various 

 parts of the tJnion of South Africa detailing the occurrence of new 

 outbreaks and the number of farms that have been freed from 

 quarantine in various provinces. Dipping operations throughout the 

 Union have been greatly interfered with owng to the scarcity and 

 increased cost of dipping materials. It is much regretted that many 

 farmers are indifferent to the erection of dipping-tanlvs, and the 

 number of these in use is increasing but slowly. 



Mange has been very prevalent in the vicinity of Port Elizabeth, 

 mainly amongst donkeys belonging to natives ; outside this area the 

 disease has given little trouble.

Experiments conducted in consequence of a report published at 



Strassburg in 1914 to the effect that pernicious anaemia is produced 



by the agency of bots [Gastrophihis], showed that bots collected from 



the stomach of a horse that had died of this disease, when emulsified
