INFLUENZA. 65 



If the lungs are affected, blankets wrung out of hot water, 

 mustard, etc., may be applied to the sides of the thorax ; 

 but severe counter-irritation is not to be recommended. If 

 costiveness is present, use injections, or ol. lini. 5vi. — sviii., 

 or aloes b.b. 5ii., may be given. In abdominal complica- 

 tions, when colicky pains are present, opii pulv. 51., or opii 

 tr. 5i., may be given; or a hypodermic injection of morphia 

 may be given in certain cases ; but as a rale they are 

 objectionable, as they cause too great depression. Great 

 benefit sometimes accrues from steaming the throat ; when 

 convalescing, ferri sulph. and chloride, quinine, potass^ 

 iodid., etc, may be used; and good grooming is an 

 excellent aid to recovery. Potassium iodid. is useful in 

 the hepatic complication. Formerly, when bleeding was so 

 much practised, influenza was attended with very great 

 fatality.

STRANGLES. 



Definition. — An eruptive fever peculiar to the horse, 

 usually affecting the organs of respiration to a greater or 

 less extent, with the formation of a hard tumour in the sub- 

 maxilhiry space. It is peculiar to youth, generally attacking 

 animals from two to six years of age ; yet it may occur in 

 a sucking colt, or in a horse twenty years old. After 

 occurring once in a well marked form, it never again 

 attacks the same animal. The disease was first called 

 strangles by Gervase Markham, a couple of handT'ed years 

 ago, and received the name on account of the urgent 

 symptoms of strangulation manifested. Strangles, so far 

 as I know, is peculiar to the equine race, and does not 

 attack any other species of animal. The areolar tissue is 

 the first to become affected. The tumour forms sometimes in 

 the groin, behind the shoulder, and not unfrequently in th-e
