MUEEAIN IN CATTLE. 



The subject of murrain in cattle has of late years received 

 a good deal of attention, and, little by little, we are acquiring 

 more definite ideas in regard to this disease, as well as to its 

 influence upon the healthfulness of the milk and flesh of the 

 animal. The experiments of Chauveau have shown that tu- 

 berculosis of cattle is transmissible; that is to say, by bring- 

 ing sound cattle in communication with those that are dis- 

 eased, similar tubercles become developed in the former, or, 

 in other words, they become afflicted with murrain, which is 

 only another name for tuberculosis. 



The investigations of Professor Klebs, in Berne, have shown 

 still further that the transmissibility of the disease is not lim- 

 ited to cattle, but may also extend to other animals ; indeed, 

 he has been convinced that the human tubercles are equally 

 transmissible with those of cattle, and that murrain in cattle 

 owes its orio-in to the same infectious material as the human 

 tuberculosis. Thus, certain Guinea-pigs, having been fed with 

 the murrainous matter, w r ere infected with it, and others, 

 treated with the tuberculous matter from man, exhibited the 

 same result. 



Again, murrain has been produced in cattle from feeding 

 or inoculating with the human tuberculous matter, and hence 

 it follows that the tuberculosis is transferable from cattle to 

 man, and it appears highly important that murrainous ani- 

 mals should be carefully watched, and that inspection of their 

 meat should be very strictly attended to. 



Professor Gerlach, of Hanover, has lately prosecuted addi- 

 tional experiments upon murrain, and has established not 

 only its transmissibility by inoculation, but also has shown, 

 by numerous experiments, that tuberculosis can be transferred 

 by feeding with the milk of murrainous cattle. As conclu- 

 sions from the facts ascertained by him, Professor Gerlach re- 

 marks that, up to this time, murrain lias been looked upon, 

 in a sanitary aspect, as an innocent disease, but that it must
