quickened. In the neighbourhood of the throat there is swelHng-, and this 

 may occupy the space between the branches of the lower jaw, or it may be 

 formed on one side of the throat only, or it may be more generally diffused 

 among the tissues. The swelling gradually enlarges, and eventually one or 

 more abscesses are formed. When the throat becomes, a > it sometimes does, 

 more severely affected, the structures forming the upper part of the wind-pipe 

 become so much swollen that breathing becomes difficult, and thus while the 

 horse breathes there is caused the trumpet sound, due to the passage of the 

 air through the swollen and therefore obstructed air channel. This sound is 

 more marked while inspiring air than while expiring it, and it usually passes 

 off under treatment. Sometimes this inflammatory condition of the throat is 

 more severe and more persistent, and is a source of danger to life by 

 suffocation or strangulation. The benign form seldom extends beyond a 

 period of fourteen days, and nearly always terminates favourably. 



In the malignant or irregular form of strangles the fever is more severe, 

 and the glands which secrete the saliva become affected and may suppurate, 

 forming abscesses. Sometimes the glands in distant parts, such as those of 

 the belly form abscesses, and the fever may last a very long time. Malignant 

 strangles may be of one or two months' duration, and the animal may die of 

 various complications, viz., from poisoning of the blood by the formation of 

 matter, or from inflammation of the lining membrane of the belly. Sometimes 

 roaring or w-histling is left after recovery from strangles, but the most common 

 sequel of bad attacks of this disease is blood poisoning, resulting in the 

 formation of abscesses in various parts, more especially in the limbs. In 

 speaking of the treatment of strangles, we might repeat with advantage much 

 of what has already been said concerning influenza. In all cases w^e should 

 endeavour in the first place to isolate the infected animals as quickly as 

 possible, and to keep a careful watch over the others. According to Charlier 

 bovine animals may become infected with strangles. This observer says that . 

 he has known of its being so transmitted to beasts when lodged in a badly 

 ventilated filthy stable in which the diseased horses had been kept. Dr. 

 Fleming says that he remembers some years ago a particular stable in the 

 cavalry barracks, at Edinburgh, which was called the strangles stable. The 

 erroneous notion was then prevalent that it was necessary for all horses to 

 have the disease. Remounts were consequently always lodged there, in order 

 that they might become affected. The desired result was nearly always 

 attained. In these days of scientific enlightenment no intelligent person we feel 

 sure can any longer hold such views as these. 



We must remember that when an animal takes the infection of strangles, 

 he does not immediately show symptoms of illness. On the contrar}'-, the 

 disease first remains latent or, in other words, in an incubatoiy condition for 

 a period of one to three weeks or so. 



Having isolated the diseased animals, and having placed them under 

 proper hygienic management, we should proceed at once to disinfect the 

 contaminated stables in the manner we have already indicated while treating 

 -of influenza. This is very essential, and should never be neglected by those
