142 BIG HEAD. 



weeping from the eye on the side affected in a short 

 time a local swelling appears on the side of the face in 

 a direct line between the eye and nostril, which on 

 being pressed hard with the finger causes the animal 

 to wince, and by rubbing it gently with the hand, 

 appears to give ease to him an enlargement of the 

 jaw bone, and a considerable decline in flesh. I have 

 not discovered that the disease is attended with fever ; 

 if it is suffered to run long, it causes an affection of the 

 joints they become puffed, as if inflated with wind, 

 and in a short time those swellings become filled with 

 pus, and ultimately break, and a discharge of purulent 

 matter issues from the joints, and the animal falls, to 

 rise no more without help. It is supposed to be infec- 

 tious only in this last state of the disease. 



Cure. As soon as the swelling on the side of the 

 face appears, take a piece of white arsenic about the 

 size of a common field pea, (or about six or eight grains 

 pulverized and wrapped in fine paper, of a size only 

 sufficient to contain it,) make an incision in the skin, 

 immediately over the hard tumour, insert the arsenic 

 (or the paper containing it,) and with a needle and 

 thread make one suture or stitch, tie the ends of the 

 thread in a hard knot, bleed the horse, and turn him 

 out alone in a good pasture, or if it is cold weather, 

 put him in a stable, removed from other horses, and 

 feed him on light food in a few days the effects of 

 the arsenic will be discoverable by a considerable 

 swelling of the head, nose, and face, which will increase 

 until the power of the arsenic is exhausted if both 

 sides of the face are operated on at the same time, 

 ihe head will swell to an enormous size in about a 

 month, or six weeks, the arsenic will have developed 

 its efficacy by the appearance of a circular piece of
