MEGRIMS. 397 



quence of tlie arteries at the base of the organ being ossified ; 

 also from chronic disease of the digestive organs. Driving a 

 horse in winkers will sometimes excite the disease ; while the 

 same animal, if driven with an open bridle, may not be attacked. 



Treatment. — When the disease arises in consequence of 

 tumours within the lateral ventricles, or from ossification of the 

 arteries at the base of the brain, the disease cannot be cured ; 

 when caused, however, from disease of the digestive organs, 

 the case, in all probability, will admit of being cured. 



The best remedies, in general, are — Barbadoes Aloes, Nux 

 Vomica, Arsenicum, Pepsine, aud Sulphur. 



Baebadoes Aloes. — In two or three instances I have

 Aloes daily, until purging is produced. 



Ntjx Vomica. — Arsenicum. — "When the purging has 

 ceased, have recourse to ISTux Vomica and Arsenic. Give 

 the remedies night and morning alternately. Use the Nux 

 Vomica in 2-drachm doses of the 1st dilution, mixed with 3 or 

 4 ounces of water ; also the Arsenicum, in 2-drachm doses 

 of the 3rd dilution, mixed with 2 ounces of water. The use 

 of these remedies may be persevered in for ten or twelve days 

 in succession, or even longer, if thought necessary. 



Pepsine. — Some time ago I was consulted respecting a 

 horse aff'ected with Megrims. In addition to the disease, the 

 animal presented an unthrifty appearance ; the skin was dry 

 and harsh ; the hair staring, and its natural colour bleached ; 

 the abdomen presented a pinched-up or contracted appear- 

 ance ; the dung was dry and glazed; the appetite was moderate. 

 The animal was also afiected with diseased thrushes, and with 

 Grrease in the heel of the right hind limb. Small doses of
