nature enveloping them with a covering of dense tissue, when they cause 

 little inconvenience. 



136. Poisoned Wounds are, happily, rare in horses and cattle, 

 except when the skin has been damaged by lice, or by a scratch, and 

 the animal has subsequently been washed with arsenical sheep dip. 

 Arsenical preparations should never, under any circumstances, be 

 used for washing horses, cows, or dogs affected with lice, numerous 

 animals having been poisoned by their use. Poisoned wounds in animals 

 are sometimes also caused by a wasp's-sting, snake-bite, &c. For 

 stings, apply a diluted solution of Ammonia. In bites from dogs, the 

 best treatment is to wash the part well with cold water, and apply 

 Tincture of Iron. 



137. From wounds of ever}' description we may have a great deal of 

 constitutional disturbance — Sympathetic Fever — when the temperature 

 rises to 104° or 106°. This also must be attended to. (See Par. 

 38, First Lecture.) 



138. Lacerated Muscles. — Musclesoccasionally become lacerated, 

 or torn, without any swelling or lameness being visible, the animal 

 merely going" stiff." All the muscles of the body, those of the neck, back, 

 loins, quarters, &c. — from slipping on the ice, falling, galloping, jumping, 

 &c. — are liable to this ; and to arrive at a proper conclusion, the 

 history of what tlie animal had been doing previously is indispensable. 

 Frequently, nothing is seen until the flesh is noticed to waste away 

 from the part ; as for example, the so-called shoulder-slip in young 

 horses when first put to work. If the animal does show lameness, 

 rest, with cold water irrigation by means of the hosepipe, or tub and 

 tube irrigation, several times a day, answers well (see Par. 72, Second 

 Lecture), and a run at grass is to be highly recommended ; while, at 

 times, blistering may be found expedient. 



139. Lameness of the Shoulder may arise from many causes, 

 such as an injury to the muscles of the shoulder, or to the long muscle 

 of the neck, or to rheumatism, disease of the liver, or even a slight 

 disorder of the stomach, caused by a feed of new oats, Indian corn, ur
