60 EXPERIMENTAL FARMS. 



From this table it will be seen that of the 28 animals tested 21 showed a rise in 

 temperature of from two to six degrees Fahrenheit, thus indicating a diseased condition. 

 This result was a matter of surprise to all as so many of them appeared to be healthy, 

 vigorous and in good condition and had never shown any symptoms of disease. The 

 diseased animals were all killed the following day and a careful postmortem examina- 

 tion made in each case with the following results : 



1. Rose of Sydenham, Durham cow, 8 years. — Lining of the thoracic cavity cov- 

 ered with many large and small masses of grapy tubercle, partly cheesy and partly cal- 

 careous, peritoneum also covered with finely granular tubercles. Lungs with many 

 small patches of tubercle in their substance and small masses distributed over the sur- 

 face. About one-fourth of the udder was much affected and almost solidified with 

 tubercle. 



2. Rose of Darlington, Durham cow, 4 years. — A large portion of one lung was 

 filled with soft tuberculous matter ; the other lung was healthy. Thoracic glands en- 

 larged and filled with solidified tubercle. The udder was slightly tuberculous, and at- 

 tached to the womb there was found a considerable quantity of soft tuberculous 

 matter. 



3. Cowslip, Durham cow, 4 years. — In the right lung there were several large 

 cavities filled with tubercle, varying in consistence, some soft and partly fluid, and some 

 solidified. The left lung was healthy. Thoracic glands enlarged and filled with caseous 

 and calcareous tubercle. The tip of one lobe of the liver was also diseased by deposit 

 of tubercle. 



4. Fashion, Durham cow, 3 years. — The left lung had a large tuberculous mass in 

 its substance, grapy tubercular deposits were found on the walls of the thorax, and the 

 thorac'c glands were enlarged and filled with tuberculous matter, some of which was 

 soft but solidified and some hard and calcareous. 



5. Countess of Brandon, Durham heifer, 1£ years. — The lungs in this animal were 

 healthy and there was no appearance of disease on the lining of the thoracic cavity. 

 In the thoracic glands were found small masses of tubercle and several of the mesen- 

 teric glands were enlarged and filled with calcareous tubercle. 



7. General EL, Durham bull, 3 years. — In one lung a large abscess was found just 

 under the surface filled with solidified tubercle, some of it surrounding the cavity, being 

 calcareous. Tuberculous matter was also found in two of the thoracic glands ; in one 

 case in small quantity and in an early stage, and in the other the gland was enlarged 

 and filled with semi-solid tubercle. Some of the mesenteric glands were also tuber- 

 culous. 



9. Jewel, Ayrshire cow, 5 years. — Lungs healthy ; one of the thoracic glands en- 

 larged and filled with solidified tubercle. Small tubercles were found on the outer 

 surface of the stomach and small granules of a tuberculous character on the surface of 

 the spleen. 



11. Middlesex, Ayrshire bull, 3 years. — Substance of lungs healthy, but some small 

 tubercles were found on the surface. One of the thoracic glands was enlarged and filled 

 with solidified tubercle. Surface of the spleen also dotted with a few small tubercles. 



12. Dandy Jock, Ayrshire bull, 1 year. — Surface of both lungs dotted with 

 miliary tubercles, no disease found in their substance, lining of thoracic cavity covered 

 with grapy deposit of tubercle. Thoracic glands enlarged and partly filled with tubercle 

 most of which was in a calcareous condition. 



13. Brandon Prince, Ayrshire bull, 1 year. — Surface of one lung dotted with small 

 miliary tubercles, otherwise lungs appeared healthy. Thoracic glands somewhat en- 

 larged and filled with cheesy tubercle. 



14. Queen of "Waterloo, Holstein cow, 6 years. — In this animal the lungs and all 

 the other organs appeared to be healthy and no disease was found in any of the thoracic, 

 mesenteric or other glands, but many small tubercles were found scattered over the 

 surface of the inner lining of the bowels. 



16. — Princess of Holland, Holstein heifer, 1^ years. — The lungs were free from 

 tubercle, but specimens of a small parasitic worm were found in the bronchial tubes.
