dry, but it is attended with a very characteristic expectoration. 

 The difficulty of breathing is sometimes slight in the outset ; some- 

 times severe. 



Apart therefore, from the physical signs, we may say that the 

 usual symptoms of this disease are pain, more or less severe, dif- 

 ficulty of breathing ; cough ; a peculiar expectoration ; loss of 

 appetite ; and fever, alternated with shiverings ; though the latter 

 are usually nervous in character, rather than the result of cold. 



As the disorder progresses we have discharges of thick tena- 

 cious mucus, which becomes encrusted upon the lips and nose ; 

 the eyes become rheumy and blood-shot, the lids being frequently 

 agglutinated, especially in the morning ; and the animal seeks re- 

 pose, and is disinclined to move. Farther on we find the cough 

 becomes less frequent, or it inay cease entirely. It has no particular 

 character at any time, and affords little information, though it is 

 usually dry at the outset ; but in a few hours is accompanied by 

 expectoration of a yellowish frothy mucus which, later, becomes 

 streaked with tawny rust-colored spots, which evidently constitute 

 the greater portion of the expectoration. The discharge from the 

 nostrils undergoes the same changes. Ulcers appear upon the lips 

 in this stage, and the animal utters cries of pain, particularly after 

 pressure upon the chest. Emaciation supervenes, the sufferer 

 grows thinner and weaker, until, no longer able to rise, it remains 

 lying upon the side. The breath now has a highly offensive odor, 

 which might have been remarked in a less degree at an earlier 

 stage of the disease ; diarrhoea supervenes, and the faecal dischar- 

 ges have the peculiar fetid smell before noticed, in speaking of 

 post-mortem appearances. This is the last stage, which closes 

 with death. 



Having thus given a crude outline, I will explain some of the 

 points further : 



At the outset, the expectoration and nasal discharges consist 

 of clear mucus, or else there is no secretion ; but the second or 

 third day generally, they assume the characteristic appearance : 

 i. e., they come to be composed of mucus intimately united and 

 combined with blood, though it may be streaked with blood at 

 first, it generally is blood and mucus at the outset, and is always 

 at the expiration of twenty-four hours. Even when this trans-
