ing" to the tonsils, fauces, and g-lottis ; but a distinct inflamma- 

 tory patch about the angle of the larynx, at the back of the 

 rima glottis, is so invariably present, as to deserve the charac- 

 ter of one of the distinguishing criteria of the disease. The 

 epiglottis and rima glottis are commonly enveloped with an 

 inflammatory tinge, which, now and then, extends a little way 

 within the trachea, but less frequently is the oesophagus 

 affected with it. Proceeding onwards, we invariably meet 

 with an extension of the morbid inflammation to the thoracic 

 and abdominal viscera ; but by no means are these cavities 

 always affected in an equal degree; on the contrary, in those 

 instances where there has been a greater tendency to the 

 raging variety, the thoracic viscera are usually more inflamed 

 than the bov/els or stomach. Not only are the lungs them- 

 selves, in these cases, found highly inflamed, and often gan- 

 grenous, but the costal pleura and diaphragm are affected 

 also. Sometimes one thoracic cavity is found more highly 

 inflamed than the other, and, now and then, the mediastinum 

 pericardium, and even the heart itself, in cases of great rabid 

 intensity, are found inflamed *. 



When the abdominal viscera are examined, they almost in- 

 variably present marks of a full share of the morbid affection. 

 If the dog has been destroyed early in the disease, these may 

 not be very considerable, and an occasional case may occur 

 where the appearances are not very strong, even when the 

 animal is suffered to remain until the complaint kills him, but 

 such instances are extremely rare. The degree of inflamma- 

 tion in the stomach and bowels, particularly of the latter, will 



* It is, however, proper to remark, that the degree of inflammatory 

 appearances in either the pharynx, the lungs, stomach, or bowels, is 

 not always in exact proportion to the intensity of aflfection exhibit- 

 ed in the symptoms during life. It is also equally necessary to no- 

 tice, that the same variety in the morbid appearances occurs as in the 

 symptoms. Nothing can be asserted as invariable and certain. It must 

 also be evident, that, when a dog is destroyed early in the complaint, the 

 morbid appearances will not be the same as when he is suffered to die 

 by the force of the disease.
