TUBEECULOSLS. 509 



an ounce of nitre in the food or water, daily, for a week. If the 

 sheath be swollen, the penis should be withdrawn, the sheath well 

 washed out with soap and warm water, and afterwards lubricated 

 with sweet oil or vaseline. The back of the hand should be 

 oiled, before the hand is introduced into the sheath. If these 

 measures do not reduce the swelling, the sheath should be punc- 

 tured; for a distended condition of that part may prevent free 

 urination. The affected leg should be neither blistered nor fired ; 

 though we may endeavour to reduce its size by hand rubbing ; by 

 the pressure afforded by an elastic or flannel bandage ; or by the ap- 

 jDlication, from time to time, of the ointment or tincture of iodine. 

 The horse should on no accoimt be worked, or even taken out of his 

 stall, until all inflammatory symptoms have subsided. After an 

 attack, great care should be obsei-\^ed as to his feeding and exer- 

 cise ; for the disease has a strong tendency to recur, and, by doing 

 so, to cause a permanent thickening of the limb. 



If abscesses form, they should be freely opened with the knife. 



Colonel Fred Smith advises that during the inflammatory stage, 

 no time should be lost in freely scarifying the affected limb, and then 

 bandaging it, so as to favour the escape of the fluid portion of the 

 blood, which is the cause of the swelling and of the subsequent en- 

 largement of the leg. 



Bleeding (from the jugular vein) in this disease, should on no ac- 

 count be resorted to ; for, if practised, it will increase, to a high 

 degree, the tendency of the affected limb to become chronically en- 

 larged ; although it may apparently, for the time, be of benefit in 

 alleviating the acute symptoms. 



The subsequent feeding and exercise of the patient should be care- 

 fully regulated. 



It is quite useless to attempt to treat an old case of swelled leg 

 which has been induced by attacks of this disease. 



On account of its recurrent nature, a horse which has been known 

 to have had this disease, should not be passed sound. 



Tuberculosis 



is an infective disea,se due to the presence, in the system, of a 

 specific disease genu (the bacillus tuberculosis), which gives rise 

 to tumours of various sizes in the internal organs. Owing to the 

 fact of these tumours entering into and destroying the tissues in 

 which they are located, the affected animal wastes away and dies. 

 In advanced cases, there is generally very profuse urination. 

 It appears to be in the horse, as in man, a very fatal disease, for 

 which there is no cure. In human beings it is known as consump- 

 tion. It is a comparatively rare disease in horses.
