896 DISEASES AND THEIR TBEATMENT. 



inflammation of the bowels, or becomes seated, there will be an in- 

 clination to sweat, an anxious expression in the eye, increased res- 

 piration, the pulsation from 70 to 80, small and weak. The inner 

 lining of the eyelid will be plainly injected or reddened, the animal 

 at times looking toward the flanks; walks almost in a circle; makes 

 attempts to lie down, coming down about half way, gets up and 

 walks around again, which may be repeated a number of times ; 

 finally succeeds in getting down, which he does very carefully, then 

 will lie outstretched for a few moments ; will make an attempt to 

 rise, and will sit up like a pig, as shown in Fig. 787, page 900. 



"In colic, the horse throws himself down carelessly, rolls around 

 in a careless manner, and then jumps up, an important sign of 

 death. After the case has been treated for some time, he may seem 

 easier ; but if allowed to have his own way, and he wanders off to 

 some unusual place, it is positive proof that he is beyond medical 

 aid. 



' ( Treatment for colic. 2 ounces laudanum, ^ ounce spirits of camphor 

 or 1 drachm gum camphor, 2 ounces sweet spirits of nitre, 2 drachms fluid 

 ex. belladonna. Mix with one-half pint of water, and give as a drench. If 

 the patient is no better in one hour, repeat, and, if constipated, use warm 

 water injections.

" Flatulent colic, treatment the same as above. In the early 

 stage, if after about half an hour the patient seems no better, give 

 two ounces of essential hartshorn in water, with warm water ene- 

 mas. If by this time there is no flatus, or breaking of wind, and 

 the animal's abdomen or belly is very much distended, and is belch- 

 ing up air out of the nostrils, and commences to tremble in his legs, 

 an operation will have to be performed. Take a lance or knife 

 and make a slight incision through the skin on the right flank, (the 

 ox is always punctured on the left flank, and the horse on the right), 

 at a point where the tympanitic sound is most marked. As a rule, 

 this point is midway between the edge of the hist rib and the hip bone; 

 and about six inches from the lateral processes of the spine about 

 where the cross mark is on Fig. 785. Take trocar and canula, put 

 the point into the incision previously made with the knife. Direct 

 the instrument inward, slightly downward and forward, and hit it 

 a sharp blow with the flat of the hand to send the instrument 

 through to the hilt. Now draw out the trocar, when the gas will 

 escape. When the escape of the gas has ceased, put a finger over 

 the opening of the canula to prevent the air from filling in, and 

 withdraw. When withdrawn, rub slightly with the finger over the 

 wound, and leave it alone. Before performing the operation, give
