Distemper in Dogs and Cats. 165 



second and stronger virus is used ten or twelve days later and 

 produces a real immunity. 



The drawbacks to these methods are : ist ; that fowls are of 

 too little value, to warrant inoculation in healthy flocks ; 2d ; 

 that in infected flocks, where it is employed, the more susceptible 

 birds are usually already contaminated, and a large proportion 

 die in spite of it ; and 3d ; that it becomes a means of planting 

 the infection in new localities (Kitt). 



Treatment. The disease is so deadly that little can be hoped 

 from medicinal treatment. It has been directed mainly to gastric 

 and intestinal disinfection. Copperas and sulphuric or hydro- 

 chloric acid in the drinking water }4 to i per cent, of each is at 

 once prophylactic and curative. Friedberger and Frohuer add 

 fennel or peppermint,- and give a tablespoonful every hour to an 

 affected chicken. Other agents recommended are : carbolic acid 

 (5 : 100) by the mouth or subcutem (Nocard), salicylate of soda, 

 quinia (Cadeac), tannic acid (2 : 100), salol, naphthol, tar water, 

 etc.
