agaiust those in the skin, taking out at least two-thirds ol 

 the contents of the paunch, sewing up the Avound in the 

 stomach with the edges turned in, and that in the skin, 

 and keeping on a little gruel and soft mashes for a week. 

 This operation can be performed standing, the right side 

 of the animal applied against a stone waU, and the nose 

 held by bull-dog pincers or even by the fingers. It usually 

 succeeds if resorted to early enough.

A dry baked state of the contents of the manifolds is found 

 in all feverish conditions, in torpid or inactive states of the 

 paunch, with impaired or suspended rumination, in case of 

 feeding on dry, fibrous, indigestible elements (bleached with- 

 ered hay or that which has been over-ripened, or a mixture 

 of fresh and dry grass in autumn,) on a sudden change to the 

 over-stimulating fresh grass of spring, on smutty maize, 

 cornstalks or wheat, on a deficiency of water, or a sudden 

 change from soft to hard water, or on taking lead into the sys- 

 tem in a metallic condition or otherwise. The most rapidly 

 fatal cases result from green food, over-ripe but uncured 

 grain, vetches, or rye-grass, and from lead poisoning. Breed- 

 ing ewes when fed grain become impacted, stupid, delirious. 



Symptoms. Slight cases may be marked by failure to 

 chew the cud regularly when recovering from a fever, a poor 

 appetite, dry muzzle, duU eyes, spiritlessness, quickened 

 breathing with a moan at intervals roused at any time by 

 forcibly punching the closed fist beneath the short ribs on 

 the right side. If it has lasted several days the fist pressed 

 into the left side may detect the contents of the paunch col- 

 lected in hard masses, and tympany is Hkely to be present. 

 The dung is usually scanty and hard, but in cases occurring 

 from fibrous or irritating food, this costiveness is preceded 

 by more or less diarrhoea. The beast leaves its fellows, 

 reclines on its left side, with the head in the right flank, 

 and tends by-and-by to show palsy of the hind limbs 

 drowsiness and stupor, or deliriiim and convulsions.
