286 EPITOME OF EVIDENCE ON PLEURO-PNEUMONIA. 



get an inflamed patch, and yet not get proper inoculation. If I 

 saw the proper exudate of pleuro-pneumonia, I would have no 

 difficulty in knowiug it. I would not like to say anything 

 against any inoculator, but some of them give very bad results. 

 An animal that dies from inoculation, dies from blood-poisoning. 

 It might be by the excessive development of the microbes of 

 pleuro, or from their being too active, and producing too much 

 febrile derangement, in cases where there is a development of the 

 disease to such an extent as to involve the whole of the struc- 

 tures of the haunches. You may get blood-poisoning from a very 

 pure lymph in this way, but you can easily escape from the bad 

 effects of it by cutting off a portion of the tail as soon as it de- 

 velops sufficiently. That is the common plan, and it is a very 

 satisfactory one. I know that if it gets beyond the region of the 

 tail, and involves the whole of the back parts, it produces death, 

 by the animal not being able to perform the natural functions. 

 This cannot be always prevented unless by daily and regular 

 attendance during the currency of the inoculation, which it is 

 seldom possible to give. In the case of one animal, I allowed 

 it to get beyond my reach before I knew where I was. The 

 disease had extended upwards between my weekly visits so 

 rapidly that when it was observed it had gone too far to 

 be stopped. That was the only death from inoculation that 

 occurred in my hands. I have in a few cases cut the tail 

 three or four times, and left nothing of it but the stump, and 

 yet the animals did well. In some cases the disease goes very 

 quickly up to the root of the tail. If you have had experience, you 

 will have recognised how soon it goes up. You may see nothing 

 wrong about the tip or where the inoculation has been done, 

 but the inoculation is not there ; it is further up. These are the 

 unfortunate cases. I have had several others that threatened 

 to go in that direction, but through taking such measures, as the 

 early and rapid snipping off of the tail, I prevented it going too 

 far. I have known wounds on different parts of the body, but 

 they did not develop any serious local lesion ; they had no after 

 bad effects at all ; these local swellings may take effect without 

 any sloughing of the part, but I have often seen a small slough 

 result from them near the root of the tail, which afterwards 

 healed up without the slightest trouble. There seems to 

 be a considerable amount of doubt in the public mind 

 about the inoculated animals being able to resist the dis- 

 ease ; I think you should test that in some way — put them 

 amongst diseased stock. I have repeatedly inoculated por- 

 tions of stock. I only inoculated three in one stock to begin 

 with, and the others Avere all dropping off round about, while 

 these three stood out healthy to the end. The result was that 

 the owner saw that it was necessary to do something more,
