57^ CLINICAL VETERINARY MEDICINE AND SURGERY 



loops of intestine were glued together, and to the parietal peritoneum 

 by numerous adhesions. The liver, spleen, and kidneys were infil- 

 trated with tubercles. All the abdominal lymphatic glands were 

 affected. The thoracic cavity contained half a pint or more of greyish 

 serosity mixed with fibrinous flocculi. The pleura was completely 

 covered with fine granulations. On its diaphragmatic portion were 

 tubercles varying in size between a millet seed and of a haricot bean. 

 Along the course of the aorta the mediastinal glands formed a 

 voluminous, fusiform, greyish mass marked with numerous little 

 greyish-white tubercles. 



The surface of both lungs — and particularly that of the posterior 

 lobes — showed prominent greyish tuberculous growths, the centres of 

 which were softened ; similar growths had developed in the depths of 

 the lungs. Even the heart was invaded, the myocardium of the left 

 ventricle showing a large tuberculous growth (Fig. 84). 



The tubercle from the heart was examined histologically, and for 

 tubercle bacilli. Almost the whole of this tubercle was composed of 

 degenerating cells. Only the periphery contained masses of living 

 cells. In places the growth had undergone fibrous change, and these 

 contained numerous bacilli. 



The cases and experiments we have described in this note appear 

 sufficiently numerous to carry conviction. We were, therefore, some- 

 what surprised to see in a recent book that the goat is refractory to 

 tuberculosis, and that up to the present day no observations have been 

 published proving the occurrence in it of tuberculous lesions. The 

 slightest bibliographical search would have convinced the author of his 

 error. 



But, if the goat possesses no immunity, what becomes of that 

 method of treatment, which consists in transfusing its blood into the 

 veins of phthisical patients ? As no serious experiments appear to 

 justify this method of treatment its application to man is entirely 

 unwarranted. Luckily the suggestion almost immediately fell into 

 well deserved oblivion.
