 in case of bronchitis, pleuro-pneumonia, hoven, aphtha, 

 etc.

 much description, as it is only an eiiort of nature to get 

 rid of something that is injurious. By its removal the

 treatment, but if it should, change of feed and pasture 

 land will be the first things to be attended to, and if ne- 

 cessary after a trial of new feed and pasture, a few powders 

 composed of prepared chalk, two ounces ; ginger, half an 

 ounce; opium, one drachm: mix and give in the form of a 

 drench, with wheat flour gruel. Repeat the dose, if it be 

 necessary, but never be in a hurry to give astringents in 

 looseness of the bowels, as much mischief may be done by 

 controverting the efi'orts of nature, which are always of 

 salutary efi'ect, if not too violent for the condition of the 

 beast, and in that case interference is now necessary.

Causes. — This is an important inquiry in cattle patho- 

 logy, for farmers are sometimes disappointed when they

 dysentery are but the symptoms. Chronic diarrhoea is the 

 sequel to tuberclulous consumption aliieady described under 

 that head. Or dysentery may show itself before even 

 consumption is either thought of or recognized. However, 

 chronic diarrhoea or dysentery is the result of tubercles
