368 History of Animal Plagues. 



and the interior appeared to be burning. The rumination en- 

 tirely ceased. In cows the lips and the vulva were swollen, and 

 from them came a virulent humour. On the teats appeared 

 purple patches. Pustules often appeared in the mouth and on 

 the tongue. The animals which recovered passed through several 

 periods or stages. At first their eyes lost their redness, and the 

 tears ceased. Their backs were covered with scabs or scales ; the 

 udders and teats were covered with small tumours or hoiitons. 

 About their necks there were a great number of these pustules 

 covered with scabs, which fell ofi' after some days, and the beasts 

 began to lick their nostrils and skins. This was particularly 

 observed at Paris, in Burgundy, and in Franche-Comte, and was 

 only noticeable in the few which recovered, and these were only 

 oxen, or emaciated cows. The hair grew stronger and smooth, 

 the milk returned, the faeces were more solid, and never any of 

 those recovered had a relapse. Some had pustules on their 

 tongues, which were scraped to the quick and then dressed with 

 vinegar and salt. 



The post-mortem appearances were : in the rumen a great 

 quantity of moist food, possessing a disagreeable odour, although 

 the animals had not eaten anything for three, four, and even 

 eight days. The leaves of the third section of the stomach 

 were black, gangrenous, and easily torn. The alimentary 

 matters between them were hard, and similar to peat ready 

 for burning ; the fourth division of the stomach {caillette) 

 was throughout of a reddish purple, mixed with patches of 

 a deep or ijright violet tint. Pus was also found in it. In 

 many subjects there were dark spots on the liver, with hydatids 

 and traces of gangrene in the lungs. The udder and adjacent 

 integument had also livid blotches. The gall-bladder was 

 generally full, and the contents were very fluid, though the 

 colour was not altered. The rectum was frequently noticed 

 to contain a little black blood. Sometimes the heart was 

 dotted over with these patches ; the uterus was affected in the 

 same way, and if it contained a foetus this was found suffocated 

 by the blood. The larynx, the pharynx, the base of the tongue, 

 the oesophagus, and the trachea had like stains of ecchymosis; 

 the cavities of the nose were filled with a purulent matter.
