The ox-warble fly [Hypoderma] may be largely controlled by 

 squeezing the grubs out of infested animals during the early spring 

 months, thus reducing the egg-laying females for the next summer. 

 The eggs are laid during the summer months mainly upon the hair on 

 the legs of cattle. The young maggots are found in the gullet from 

 September to February, after which they appear under the hide on 

 the back. It is doubtful whether they enter the body by the animal's 

 licking the eggs off the hair, recent investigations having indicated 

 that thev may burrow directly through the hide [see this Review, 

 Ser. B, iii, pp. 19, 22].

Further experiments in the transmission of swamp fever in horses 

 [see this Review, Ser. B, iv, p. 14] have confirmed the view that it is 

 transmitted by Stomoxys calcitrans (stable fly), and probably not by 

 mosquitos, nor by means of a secretion from bot-fly larvae, as suggested 

 recently by German writers.

A liniment containing crude oil and lime-water proved very effective 

 against horse mange and was, generally speaking, harmless. It 

 diminishes the appetite and may cause slight temporary oedema and 

 a more or less considerable loss of hair, but no lasting ill-effects were 

 observed. The dipping arrangements at the hospital are described. 

 The tank is similar to those used in South Africa and elsewhere for 

 freeing cattle from ticks. The dipping fluid is a 2 per cent, aqueous 

 solution of creolin at a temperature of 100°-110° F. This is non- 

 poisonous, cheap, harmless and highly effective. Very severe cases 

 were usually cured by treatment twice weekly for five or six weeks, 

 medium cases in four weeks and slight ones in three weeks. Each 

 treatment consisted of three separate dippings with a good rub-down 

 after each. After treatment, the horses were placed in warm stalls. 

 Their stalls, harness, etc., were disinfected once a week with a solution 

 of lime-water and lysol. It is possible to treat 40 horses per hour and 

 only 12 men are required for the actual dipping and rubbing down of 

 this number.
