250 Progress of Rational Pathology. 



procured from cows affected by this disease. It produces a 

 phlyctcenulous pustular eruption round the mouth, and ulcers 

 inside it, colic and diarrhoea, and at times eruptions on the 

 hands and feet. Almost all calves suckled by diseased cows 

 died of diarrhoea. Touching the diseased secretion, produces, 

 according to Siebert, an erysipelas bullosum at the point of 

 contact. 



%. Lung disease of cows — (contagious pleuro-pneumonia). 

 It is contagious, as Hertwig proved it to be, who produced it 

 by inoculation with blood and with the secretion of the nose, 

 as also by mere juxta-position with healthy cows. 



*o. Gangrene of the spleen. — There are still disputes whe- 

 ther the eating of the flesh of an animal suffering from this 

 disease is infectious, but there is no doubt of its general con- 

 tagiousness. 



p. Glanders. — Its contagiousness, at least in the acute form, 

 is generally acknowledged : views are more discordant re- 

 garding the chronic one. Magendie goes the length of con- 

 sidering the two distinct, and does not consider the chronic 

 form to be infectious. Hering proves, that chronic glanders 

 communicated from a horse to a donkey usually runs a very 

 acute course. In the way of experiment it has been un- 

 doubtedly proved, that glanders can pass from horses to other 

 animals of different genera, although the action of the poison 

 inoculated is slower and less certain, than in the solid unguli. 

 Cases of the accidental infection of men have also been observ- 

 ed, and Rayer has introduced glanders into his system of patho- 

 logy. The local symptoms are a kind of carbuncle, along with 

 the well known affections of the lymphatic glands : if the 

 disease becomes universal, then it resembles a good deal the 

 so-named reabsorption of pus. Glanders in man can be inocu-
