This paper describes a dipping-tank for army horses designed by 

 Colonel Wilson for use with lime-sulphur solution.

The larvae of the Oestrid flies affecting horses, Gastrophilus equi and 

 G. haemorrhoidalis, require treatment if present in any but limited 

 numbers. From two to five 5-gramme carbon bisulphide capsules 

 should be administered at two-hour intervals, followed on the next 

 day by a saline draught consisting of 10 to 13 oz. of sodium sulphate. 

 The best treatment for cattle infested by Hypoderma bovis is by 

 squeezing out and destroying the larvae. Another remedy is the 

 injection of 1 c.c. of tincture of iodine into the warble. Treatment 

 of Oestrus ovis infesting the nasal sinuses of sheep is difficult. A¥hen 

 the animals are valuable, the sinus may be trepanned and the 

 parasites removed or benzine diluted with water may be injected by 

 means of a special drill.

Acting on government instructions issued on 26th February 1917, 

 the Institute of Hygiene of the Veterinary College at Hanover tested 

 the disinfecting power of the blast of dry, hot air in a laboratory model 

 of the Vondran apparatus, a large type of which — used for destroying 

 lice in uniforms and other military equipment — has already been 

 described [see this Review, Ser. B, v, p. 43]. In the laboratory model 

 an electric heater is fixed close beneath the disinfection chamber and 

 the blast from the fan passes over it. There was no important 

 dift'erence between the temperature in the upper part of the chamber 

 and that in the lower part when the chamber was empty, but when 

 it was partly or entirely filled a difference of 36° F. [in the original, 

 20 degrees — by which, in this and other places. Centigrade degrees are 

 assumed to be meant] or more were observed. This difference was 

 reduced when the heater was switched off or when a constant 

 temjDerature was maintained above the chamber in the bell-shaped 

 mouth of the exhaust pipe leading back to the blower. Paper, books, 

 cardboard, clothing, leather coats, boots (wet or dry), mirrors and 

 catgut did not suffer from several hours' exposure to temperatures 

 sufficient to register 266° F. in the bell and 320° F. in the lower portion 

 of the chamber. Horn buttons became so brittle as to snap easily, and 

 newly-flayed mouse-skins were shrunk and rendered brittle by the 

 great heat. They did not suffer at 159°-177° F., which heat may be
