ought to be applied to the damaged elbow, night and morning, 

 with soothing absorbent lotions ; {see Appendix) but beware of strong 

 stimulating embrocations. Should the tumour be soft to the touch, 

 and just underneath the skin, it may contain watery fluid (serum), or 

 matter, when it will have to be opened ; if it is hard, or deeply seated, 

 a small piece of 15 per cent, of oleate of mercury, applied every other 

 day, will have a good effect. 



149. Broken Knee [see Plate IX. No. / 7) is of frequent occurrence, 

 and varies greatly as to the degree of injury. In some cases it is slight, 

 only abrasion of the skin and hair, in others so extensive that the joint 

 may be permanently damaged ; particularly so when the joints are laid 

 open and the ligaments and tendons iiijured. The parts to be treated 

 must beproperly cleansed from all sand, grit, &c., then a pledget of tow, 

 saturated in the antiseptic mixture [see Appendix), should be applied, 

 secured with cold water bandages, which must be kept constantly wet, 

 and not removed for three days, unless the leg swells very much. The 

 animal should have its head tied close up to the rack, so that it cannot 

 lie down. Any constitutional disturbance that may arise must be 

 treated as Sympathetic Fever. {See Par. 38, First Lecture). If the 

 joint be damaged, and joint oil run from the wound, a special tin 

 splint must be placed at the back of the knee, to keep it steady. 

 The cold water bandages keep the inflammatory process in check, 

 conducing to healthy action, and closing the wound by granulation, 

 which may appear in eight to ten days ; then the cloths must be 

 removed, and the wound left bare, dressing it daily with suitable 

 caustic lotions or a preparation of iodoform (see Appendix). A good 

 blister, and a run at grass, may be necessary, but the skin once 

 destroyed is never reproduced. In treating these cases, great care is 

 required in dieting the animals, keeping them cool and quiet, as at 

 times lock-jaw supervenes. When the injury is slight, dressing the 

 parts either with Friar's Balsam, or Flexible Collodion twice a day is 

 all that is required. 



150. Speedy-cut. — This is a bruise on the inside of the fore leg. 

 It may be between the knee and 'fetlock ; at the knee ; or, even, in
