PATHOLOGICAL ANATOMY 53 



in sterile 0-85 per cent, sodium chloride. Twelve 

 months later the animal was killed, and showed typical 

 and well-marked lesions of Johne's disease throughout 

 the intestines. The mesenteric glands were enlarged 

 and oedematous. The bacilli were present in the 

 lesions in fair number. Goat 2, which had received 

 I c.c. intraperitoneally, showed the disease in a very 

 early stage, and only very few bacilli were found. 

 The lesions present in these animals showed the same 

 characters as those already described in the case of 

 bovines, and, in spite of the methods of inoculation, 

 were confined to the intestine and neighbouring glands. 

 The bacillus was afterwards recovered from these 

 cases in pure culture (p. 152). 



Lienaux gives the following account of the lesions 

 found in the horse which he recently described. The 

 account is taken from the translation which appeared 

 in the Veterinary Record of April 19, 191 3 : 



" Post mortem, two lymphatic glands — one in 

 the great mesentery and one in the meso-colon — 

 were found absolutely caseous, though little en- 

 larged. These were the only lesions of tubercu- 

 losis present. But extensive and serious lesions of 

 the intestine existed, which were especially well 

 marked upon the caecum and double colon. The 

 walls of these two viscera were thicker and more 

 consistent than normal, and the small intestine 

 was altered in the same direction, though to a 

 much less degree. The lymphatic glands dis- 

 posed along the caecal and colic arteries were 

 slightly tumefied and turgescent, and along the 

 same vessels large distended lymphatic trunks, 

 filled wnth yellowish lymph, could be distinguished. 



" The mucous membranes of the caecum and 

 large colon were very thick. Their free surface
