eflbrts to escape will tumble headlong. A nervous trembling is 

 frequent, and there is tenderness or itching of the loins or croup. 

 Treatment of the lambs would be on the same general prin- 

 ciples as in inflammation of the spinal cord in other animals, 

 but will rarely pay. Prevention is to be sought by keeping 

 breeding ewes and young sheep from newly-limed land; by 

 using none for breeding under two years old, and, by close 

 attention to food, water, and shelter, to secure good health 

 during pregnancy. 



PARALYSIS. LOSS OF SENSATION OR VOLUNTARY .MOTION. 



Loss of volujitaiy motion is known as Motor paralysis, loss of 

 sensation as Sensory paralysis or Anesthesia. Paralysis is also 

 peripheral when it occurs from injury to the nerves (chilling, 

 tearing, cutting, pressure, inflammation, degeneration, etc.), and 

 central when it arises from injury to the great nerve centres, the 

 brain and spinal cord. Sensory and motor paralysis may exist 

 independently of each other, and loss of sensation on one side 

 of the body may coexist with increased sensitiveness on the 

 other. An injury to one side of the brain usually paralyses 

 sensation or motion on the opposite side of the body. Injury 

 to the lower part of one lateral half of the spinal cord, paralyses 

 motion on the same side of the body behind the lesion ; while 

 an injuiy to the upper part of one lateral half of the cord 

 paralyses sensation on the opposite side behind the hurt, and in 

 a small adjacent part of the same side, while the rest of this 

 side behind the lesion is rendered more sensitive. Space 

 forbids our following further the indications furnished by the 

 nature and seat of the paralysis, as to the probable lesions in 

 the central nervous system ; this must be left for a larger work.

Paralysis of the face, trunk, and extremities, but without the 

 implication of the muscles of respiration, may arise from pres-
