MEGRIMS. 397 



quenee of the 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. 



Teeatment. — 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 best remedies, in general are, — Barbadoes Aloes, Nux 

 Vomica, Arsenicum, Pepsiue, and Sulphur.

 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.

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

 The animal was also affected with diseased thrushes, and with 

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