does the abscess of simple strangles. As a rule, these swellings 

 appear between the branches oi the lower jaw (their typical 

 position), at the base of the neck, at the point of the shoulder, 

 under the shoulder-blade, in ihe chest, or in the abdomen. When 

 they are under the jaw, they remain hard and indolent, and may, 

 even, diminish in size. At other times, particularly when affecting 

 the lymph-glands at the point of the shoulder, tiie abscess is oi 

 great extent, and the pus well formed. Here we have a case of 

 abscess due to pyaemia, similar to that described on p. 78. The 

 internal glands usually affected, are those of the mediastinum, the 

 partition that divides the cavity of the chest into two parts; and 

 the mesentery, the membrane that suspends the intestines from 

 the roof of the abdomen. In both cases a fatal termination may be 

 expected. When the mediastinum is involved, there is cough, 

 difficulty of breathing, and dropsical swellings of the chest. When 

 the abscesses occur in the mesentery, the most prominent and 

 characteristic sign is a total loss of appetite, or an apparent 

 loathing of food associated with occasional colicky pains. The 

 existence of these pains points to interference with the action of 

 the intestines. 



In these complicated cases, the febrile symptoms are, generally, 

 better marked than in the simple form ; especially, when the in- 

 ternal organs are involved. If the teiuperature rises to 104° or 

 105° F., there is good reason for concluding that an internal 

 abscess is in course of formation. When death occurs, it is almost 

 always due to blood poisoning. " Frequently and particularly at 

 the time of convalescence, purpura appears as a complication of 

 strangles " (Friedberger and Frohner). In some cases, for a 

 month, or even more, before the abscess appears, the aniinal loses 

 condition ; his coat stares ; he becomes '' hide-bound " ; has a 

 cough; and is' "out of sorts." This state has been sometimes 

 mistaken for glanders. 



The PERIOD OF INCUBATION is stated to vary from three 

 to five days. Friedberger and Frohner put it at from four to 

 eight days. 



TREATMENT. — If the animal be at grass, he may be taken up 

 and put into a comfortable box, which should possess every con- 

 dition necessary for health ; such as, proper ventilation, good 

 situation, ajid freedom from crowding. At the same time remember 

 that attacks of strangles are often so mild, that an affected animal 

 which is at grass, need not be taken up ; supposing, of course, that 

 the weather is favourable. Under such circumstances, I would 

 prefer to leave him at grass, with a comfortable hovel or loose box
