contain in some cases an admixture of blood. In a large numoer 

 of cases red spots are seen between the hind legs, behind the ears, 

 and on the nose and neck. Toward a fatal termination of the 

 disease, this redness changes frequently to purple. As the dis- 

 ease progresses the animal becomes weaker, and there is lameness 

 in the hind leg. The animal, when standing, carries the head 

 near the ground. As the fatal termination approaches, there will 

 be fetid diarrhoea, taking place of costiveness. The voice be- 

 comes faint and hoarse, and the animal is unconscious; the skin 

 becomes wrinkled and dry, with a cold, clammy sweat. In those 

 few cases in which the disease has not a fatal termination, the 

 symptoms above enumerated gradually subside. The hacking 

 cough remains for a long time. 



MORBID ANATOMY. 



A more or less hepatization of the lung, so extensive in some 

 cases that a portion of the lung will sink like a rock in water. 

 The lymp'hatic glands are enlarged, as also the mesenteric glands. 

 In some cases they present even a brownish or blackish color. 

 ISTumerous bacilli suis are found in these parts and in the lung. 

 The trachea contains a frothy mucus; its mucous membrane con- 

 gested and swollen. The pleura and pericardium contain a straw- 

 colored serum. The heart is more or less congested; is flabby 

 and dark in ap^oearance, owing to the engorgement of its blood 

 vessels. Tumors or morbid growths appear on the mucous mem- 

 brane of the intestines, varying in size from that of a pin's head 

 to a pigeon's egg. They are of a grayish-black color. These 

 tumors contain innumera'ble bacilli suis, and are found through- 

 out the intestines. Tumors may now and then be seen on the 

 mucous membrane of the gall, bladder, stomach, and uterus. 

 Slight changes appear in the liver, pancreas, and spleen. Morbid 

 changes are sometimes seen on the mucous membrane of the eye, 

 the lower jaw, and in the skin. Xumerous small growths de- 

 velop, extendine: but slightly into t^he cutis, but causing a com-
