 limbs are dragged as though partially paralyzed. In certain positions he 

 suffers hut little excepting an occasional cramp-like twinge, which Is 

 sometimes veiy severe and elicits a sharp outciy. While the parts affected

There are few or no constitutional symptoms, slight if any fever, and 

 the appetite is rarely impaired. Aside from the tenderness there are no 

 local signs, such as heat, swelling, and redness. In chest-founder or 

 kennel-lameness the affection exists in the muscles of the shoulders and 

 fore legs. The disease may appear either in the acute or chronic form ; 

 the duration of the former varies from a few hours to several weeks. The 

 chronic form is ohstinate, and persists usually for months. Exposure to 

 cold and damp is an important factor in the causation of this form of 

 Rheumatism. 



The local treatment consists of soothing applications in the acute foi-m, 

 and blisters or stimulating liniments in the chronic. Measures to improve 

 the general health are important, and iron and other tonics are to he given

E<RVPTivE Fevers. 



Cases of small pox and measles occuring among dogs are on record, and 

 .the symptoms of the former malady are given at length hy some authors. 

 In the one reported case of measles it was stated : " A dog licked the hand 

 of a child lying in hed, and on whom the measles eruption was at its 

 height. Twelve days later the dog sickened and suffered for two days 

 with nasal discharge; and four days later died, wlthmarked congestion of

 chiefly affects young dogs, although old animals are not exempt. One

" Sjimplomt.—'nie disease commences with fever, which continues for

 of the hody, though rarely on the hack and sides of the trunk— of red 

 points, resembling flea-hites, which are quickly transformed into nodules, 

 and then into vesicles. The contents of these become purulent, and finally 

 dry into a crust, whose shedding leaves a naked cicatrix. 



" In the dog, as in the sheep and pig, there are differimt forms of the 

 disease, and it Is henignant or malignant accordingly. Puppies nearly
