96 SPECIAL CATTLE THERAPY 



]]' the aiiiiiial is in pasture or yard she races about, 

 pa-rting up the earth, and rushing wildly at all who 

 approach. ,K\'i(lently thci'e is no true hydrophobia 

 (or i'ear of water) for cows atfected with rubies will 

 plunge into creeks, tanks, or other receptacles' for 

 water. They are unable to drink, however, because of 

 well-marked dysphagia. 



Later, these spells of ferocity, whii'h in the begin- 

 ning are of short duration become more prolonged 

 and recur at shorter intervals. In all from six to 

 twelve hours are spent in this actively furious stage. 

 The symptoms then become somewhat milder ; the cow 

 shows some lack of co-ordination in movement ; there 

 is now ptosis of one or both lids, and general evidences 

 of both nerve and muscular exhaustion. After a few 

 hours of staggering about she goes down, lying in odd 

 positions and struggling in convulsions, sometimes for 

 hours, before death comes. 



In our cases the whole course of the disease, from 

 initial signs to termination in death, rarely required 

 more than thirty-six or forty-eight hours. 



The treatment of rabies is considered hopeless once 

 it develops; the only hope lies in prophylaxsis. Sev-

 cilities for supplying vetei'inarians with the preventive 

 ti'patment of Pasteur; the inoculation for each day is 

 sent by mail in the order in which it is to be used. 

 While the treatment is too expensive for common cows 

 we recommend it in valuable animals that have been 

 attacked by rabid dogs. Animals showing symptoms 

 of rabies should either be permitted to develop the 

 disease fully so that the diagnosis may tie made reason- 

 ably certain by clinical means, or they should be im- 

 mediately destroyed and the head submitted to the 

 laboratory for diagnosis. Either of these procedures
