stables, or forbid any sale from them until all infection has ceased 

 and the buildings have been thoroughly disinfected. Compel 

 thorough disiiifection of stables, yards, cars, boats and other public 

 conveyances that may be open to reasonable suspicion of infection. 



Immunization. An attack renders the subject immune, but 

 this may be early overcome by marked change of location, and 

 exposure to a virus of greater intensity or modified quality. 

 Besides the crude and reckless Russian method already referred to, 

 direct inoculation of the virulent products has been often resorted 

 to from the time of Gohier onward, in the different countries 

 of Europe. By selecting the matter from the abscesses or nasal 

 discharge of a mild epizootic, and preserving the inoculated 

 subjects in clean, dry, pure aired stables, on nourishing diet, and 

 under the best conditions of hygiene, a fair measure of immunity 

 was conferred with absolutely no loss. The same as after casual 

 cases, second attacks will sometimes be shown, but even in severe 

 outbreaks, of a less violent type. The pus from the abscess, or 

 the preceding exudate in the swelling may be simply rubbed on 

 the nasal mucosa, or injected subcutem in another part of the 

 body. In many cases there follows merely a local cellulitis, while 

 in others the general infection leads to the nasal discharge, with 

 or without the submaxillary abscess. 



This method is open to the individual owner where no con- 

 certed effort is made to stamp ^w/the infection. When, however, 

 police measures for suppression are in force, it must be strictly 

 prohibited, or adopted only under official control, and with 

 absolute seclusion and thorough disinfection. 



Treatment. In mild regular cases hygienic measures only are 

 demanded. Cleanliness, dry stalls, pure air, warmth (a sunny 

 exposure if available), nourishing, easily digested food, (^grass, 

 green corn stalks, bran mashes, roots, carrots, turnips, apples, 

 potatoes, ensilage, scalded oats or hay) and pure water, or linseed 

 tea, grooming and, in cold weather, blanketing may suffice. 

 Rest is indispensable, though exercise may be allowed in a 

 sheltered or sunny field or yard in fine weather. 



Castrations and all other surgical operations are forbidden. 



For costiveness or tardy action of the bowels i , 2 or 3 ozs. of 

 sulphate of soda may be allowed daity in the drinking water.
