PlEtrEO-PNEUMONIA. 



18 characterized by the animal having lost the power of 

 standing. Palsy may be partial or complete. 



Cause. Tumors on the brain ; injury to, or softening of 

 the spinal cord. 



Symptoms. Inability of the animal to move, continued 

 laying; will usually eat and drink as if nothing were 

 amiss, and will continue to do so for many weeks. 



Treatment. We are in possession of only one drug, 

 which is oftentimes of service in curing this disease, de- 

 pending on whether the paralysis be from reflex action 

 of the nerves of motion, or from entire suspension of 

 feeling. If the case be from reflex action, then this 

 medicine had better not be given; but if the nervous 

 feeling be entirely lost, strychnia may then be given in one 

 grain doses twice in the day in the animal's feed, and 

 continued for a week or two.

 — Epizootic Pleuro-pneumonia. Pleuro-pneumonia is a 

 compound disease, as its name indicates — pleuro and pneu- 

 monia. My own opinion is, however, and it is almost a 

 certainty, I think, that the single name plewrisy would 

 cover the whole ground ; for the pathology of the disease
