REPORT OF THE DIRECTOR AND ACTING AGRICULTURIST. 73 



13, 14, 15, 16, 17, 22 and 32. The remainder were killed and post mortem examinations 

 made. Dr. D. McEachran, Chief Veterinary Inspector, of Montreal, was present and 

 superintended this work and was assisted by Drs. James and Perley, of Ottawa. 



Physical examinations were made of several of the animals before they were 

 slaughtered, but the results only confirmed the opinion now generally held by the best 

 veterinary authorities that it is practically impossible to detect the presence of this 

 disease by the most careful examination, except in advanced caaes and where the more 

 important organs are considerably involved. 



No. 2. Devon Bull. — Earl of Salcomb, age 5 years ; bred at the Experimental 

 Farm ; was tested in 1893 and did not then react. Post mortem — Lungs full of masses of 

 soft tubercle, some cheesy. The liver and mediastinal and bronchial glands all contained 

 tubercle in a soft condition, most of it indicating comparatively recent formation. 



No. 3. Canadian Bull. — Quintal, age 7 years. Was tested in 1893, but did not then 

 react. Both lungs somewhat diseased, containing nodules of tuberculous matter. A small 

 quantity of tubercle was found at the apex of one lobe of the liver. Bronchial and 

 mediastinal glands diseased and partly filled with tubercle. 



No. 4. Ayrshire Bull. — MacDuff, 9 years. This bull was tested in 1893, but gave 

 no reaction then. In one lung there were several small masses of tubercle in different 

 parts of its substance. Mesenteric glands, liver and peritoneum all slightly affected. 



No. 5. Holstein Bull. — Netherland Chief, age 5 years; bred at the Experimental 

 Farm ; was tested in 1893, but did not then react. A careful examination of all the 

 organs and glands was made and no evidence of disease discovered. In this instance 

 the reaction after the injection of tuberculine was comparatively slight. 



No. 8. Nancy. — Grade cow, age 10 years; bought in 1894. In the lungs there 

 were some small patches of tubercle, the mediastinal glands were considerably diseased 

 and the bronchial glands slightly affected. 



No. 9. Mayflower. — Grade cow, age 9 years : bought in 1894. In this animal 

 both the lungs and mediastinal glands were considerably diseased. 



No. 11. Clara. — Grade cow, age 7 years; bought in 1895. Lungs grown to the ribs 

 and diseased in spots. Bronchial and mediastinal glands considerably affected with 

 soft tubercle. 



No. 18. Annie Rooney. — Grade cow, age 6 years : bred at the Central Experimental 

 Farm; was tested in 1893, but did not then react. One of the mediastinal glands -was 

 slightly affected. Diligent search failed to reveal any diseased condition in any of the 

 other glands or organs. 



No. 19. Pauline. — Grade cow, age 12 years ; bought in 1893. In this cow the spleen 

 was very much enlarged and thickened and the interior was filled with masses of 

 tubercle, and one end of this organ was much decayed, of a dark colour, almost black, 

 and gave a very offensive odour. The left lung was very badly diseased. The bronchial 

 and mesenteric glands were also much affected. The indications in this case were that 

 the disease had existed in the animal for a long time. 



No. 20. Topay. — A grade cow, age 6 years ; bred at the Experimental Farm ; was 

 tested in 1893, did not then react. In this animal the retropharyngeal, mediastinal 

 and bronchial glands were all slightly affected, but no disease was found in any of the 

 large organs. 



No. 23. Lily Rex. — A Jersey cow, age 4 years ; bred at the Experimental Farm ; 

 was tested when a calf in 1893, but did not then react. Small quantities of tubercle 

 were found in several parts of the lungs. The mediastinal glands were also considerably 

 affected. 



No. 25. Louette. — A grade cow, age 7 years; bought in 1893. The mesenteric 

 glands, mediastinal glands and peritoneum were all slightly affected. Disease was also 

 found to a slight extent in the udder. 



No. 28. Dolly. — A grade cow, age 6 years ; bought in 1893. The liver, mesenteric 

 and mediastinal glands were all slightly tuberculous. 



No. 31. Rosella. — A grade heifer, age 2^ years; bred at the Experimental Farm. 

 Anterior lobe of left lung considerably diseased ; mediastinal glands also tuberculous.
