THE1IL PATHOLOGY, DIAGNOSIS, AND TREATMENT. ■ 17 



of one ounce of tincture of arnica to a pint of cold water, keeping the knee 

 constantly wetted till granulation takes place, after which the wound 

 should be dressed once or twice a day with the following: 



Lotion for Broken Knees.— Take crystal carbolic acid, ldr. ; glycerine, 

 15dr. ; water, 2oz. ; mixed to form a lotion. 



In cases where the skin has been ruffled or puckered by dragging along 

 the ground, and a pouch or bag formed, suspected of retaining dirt, Mayhew 

 recommends the insertion of a seton at the lower part of it, to form a 

 drainage for the escape of the foreign irritating bodies. 



In no case of broken knees should officious knowing persons be per- 

 mitted to probe the wound or inject strong stimulating or caustic fluids ; 

 this, ignorant ostlers and farriers are sometimes permitted to do, and even 

 oil of vitriol has been used in such cases — such treatment is not only 

 most injurious, but cruel and barbarous in the extreme. When the 

 wound is healing, should proud flesh appear it may be kept down by dust- 

 ing with powdered sulphate of copper (blue stone), but if the carbolic acid 

 lotion is used as prescribed, this is not likely to be needed. The 

 horse should at first be racked up, and if the blister is afterwards 

 used as recommended, he should wear a cradle to prevent him gnawing. 

 The comfort of the animal suffering from injury should be specially 

 attended to, both on the grounds of humanity and as a means of cure ; the 

 feed should be light, consisting of mashes, steamed corn, and chaff, with 

 roots, clover, or vetches, as the season and circumstances afford. After the 

 wound is healed the blemish left will be diminished if the hair is taken 

 off all round for some inches and the place blistered with the following : 



Hair Stimulant— Red iodide of mercury ointment— this is made by 

 mixing one part of red or biniodide of mercury with ten parts of lard 

 or resin ointment. 



In using this ointment, it should be rubbed in with considerable fric- 

 tion, but not long enough to cause blistering, and it will be found to 

 increase the growth of hair, moreover, the new hair will be all of one 

 shade of colour, so that the blemish will be less noticeable. There are 

 many other things in use to cause the hair to grow, tincture of iodine is 

 sometimes used for this purpose, and gunpowder, mixed with lard, is a 

 common application, but it can only help to conceal the blemish by colour- 

 ing the part. The following ointment will, sometimes, have a good 

 effect, but it must be remembered that where the roots of the hair have 

 been destroyed it is impossible to make hair grow : 



Camphor Hair Stimulant.— Powdered camphor, 2 drs. ; powdered can- 

 tharides, 1 dr.; mild mercurial ointment, 2oz. ;- mixed, and a little well- 

 rubbed in twice a day. 



I believe, however, the red iodide of mercury will be found to be the 

 best hair stimulant. 



Broken Wind.— Of all classes of suffering animals claiming the 

 sympathy of the humane perhaps none are so much to be pitied as the 

 broken winded horse— past the prime of life, and suffering from a painfnl
