PHLEBITIS. 235 



problem, and one as yet for which no explanation is offered. 

 In some cases abscesses form, and a series of them may 

 extend up the course of the jugular vein as far as the parotid 

 gland, and if not checked cause complete obliteration of the 

 vein. 



Sjjmptoms. — Two or three days after bleeding a swelling is 

 observed to exist along the course of the vein, and extending 

 from the wound toward the head. On manipulation pain 

 is expressed by the animal. Pressure on the vein below 

 the wound fails to raise the vein. There may be slight 

 constitutional symptoms manifested by a quickening of the 

 pulse, etc. The swelling increases, and if the animal is on 

 pasture where the head is depressed during grazing, the 

 swelling in some cases becomes enormous. There may be 

 rigour more or less marked. The vein can be felt hard and 

 corded underneath the skin, which is movable over it. 



Treatment, — The treatment, to be successful, must be 

 energetic. The horse should be tied up and have his head 

 elevated, and fomentations are to be freely used, hot 

 water being applied, not for five or ten minutes at a 

 time, but for several hours at a time, after which the 

 parts should be nicely dried, and kept warm by means 

 of poultices. Laxative and diuretic medicines will be 

 found useful, and may be given if the system of the 

 animal is in fit condition for their reception. Careful 

 attention should be paid to the diet, which should be of a 

 cooling and laxative nature, avoiding Indian corn, etc., 

 which tends to heat the system and increase the inflamma- 

 tory action. If the case is of some standing, and abscesses 

 have formed, they should be treated in the ordinary way by 

 the application of poultices, etc. After the abscesses have 

 closed a blister may be applied over the course of the affected 

 portion of the vein. Hydrarg. biniod. may be used. A com- 

 mon result of phlebitis is obliteration of the vein. If it is
