PAETUEIENT PARALYSIS (MILK FEVER) 237 



injection process. A broad tape is tied around the teat and left 

 on for about six hours. 



The injection may be repeated in three to six hours if neces- 

 sary. In an emergency, an ordinary bicycle pump connected 

 by rubber tubing to a milk tube may be used, but this, of course, 

 does not filter the air. 



Prognosis. — It is difficult to make an accurate estimate. But 

 there is in general a good prospect of recovery in serious look- 

 ing cases if they are properly and promptly treated. 



Sudden and unexpected variations occur. Mortality under 

 the air treatment is not large. The prospect is less favorable if 

 the case develops soon after calving; if it develops rapidly 

 and seems to overwhelm the system; if there is decided loss of 

 animal heat ; if tympanites or bloating, or convulsion occurs ; 

 if the cornea becomes insensible; if the lower lip hangs loosely. 



The prospect is favorable if: the circulation remains good; 

 if feces are passed ; or the patient attempts to rise or eat ; if 

 rectal irritation causes a discharge of feces, or a subnormal tem- 

 perature changes to normal.
