272 EPITOME OF EVIDENCE ON PLEURO-PNEUMONIA. 



you generally find that the tissue which connects the lobes of 

 the lung together is consolidated and thickened. You have 

 great broad bands connecting the lobes, but in simple pleuro 

 the bands are narrow. That is one change of structure that 

 helps you. In the contagious disease we have the lobes them- 

 selves consolidated. They become of a sort of grey marble in 

 appearance, which is not so well seen in simple pleuro-pneumonia. 

 I shall now give you my experience of the last stock that we 

 dealt with in Glasgow, because it is a very interesting outbreak 

 in many respects. The outbreak was amongst Mr Salmond's 

 stock, at 207 North Woodside Road. He reported that he was 

 suspicious of having pleuro-pneumonia in his stock. That was 

 on 8th February, and at that time he had thirty-seven cows in 

 his byre. On examination it was evident that one of the cows 

 had a chest affection, and, as far as I could make out, it Avas 

 pleuro-pneumonia. On killing the first cow I found both of her 

 lungs affected. She had well-marked evidence of contagious 

 pleuro-pneumonia. The following day we took out other two 

 cows. We had now good ground for going upon, and we had 

 no hesitation in the matter; one animal's lungs were badly 

 affected, and the other animal was only recently attacked. I 

 find the temperature generally ranges from 103° to 106°. Mr 

 Salmond, hearing so much about inoculation in Edinburgh, was 

 anxious to have his stock inoculated, and, after interchange of 

 letters, he was permitted to do so. I said, " You will be allowed 

 to inoculate your animals at your own expense ; but you are 

 clearly to understand that you are not entitled to any compen- 

 sation from the local authority. If the inoculated animals show 

 well-marked signs of pleuro-pneumonia they will be removed 

 to the slaughter-house, and I will remain the judge." In 

 Glasgow I value the animals, and pass what I think are fit for 

 human food. I said I would not inoculate them myself, or any 

 one connected with the College, for the reason that I am acting 

 for the local authority. So Mr Rutherford came through that 

 afternoon, and the lungs of an animal that had been killed in 

 the morning were obtained for the lymph for inoculating the 

 other cattle. Wishing to experiment with the same lymph, 

 and for a test case, I brought from my f;irm a cow seven years 

 of age, that had been always healthy, and within six weeks of 

 her calving. I had her brought to the College along with two 

 yearling Ayrshires, and a yearling bull. I said to Mr Rutherford, 

 " I want you to inoculate this cow, and the two heifers, but not 

 the bull. We will allow the bull to congregate with the two 

 heifers. I want the brown cow inoculated, and as soon as 

 she has recovered from the operation, I want to put her into 

 Salmond's byre." On 9th February Mr Rutherford inoculated 

 Salmond's cows and also the cow in calf, and the two yearling
