EXPERIMENT STATION BULLETINS. 327 



"College Victoria Duchess. — This cow was thin in flesh for a long time, and all 

 winter, spring and summer remained in a most unthrifty condition. She was slaugh- 

 tered on suspicion of disease in pursuance of plan on October 17, 1890. No symptoms 

 or evidence of tuberculosis were found on post-mortem examination by Dr. Grange. 

 Great quantities of foreign matter were found in the second stomach, sufficient, in the 

 doctor's opinion, to set up chronic inflammation of the parts. Many sharp pointed 

 nails had pierced the walls of the stomach. 



"Phornix 2 was sold to S. S. Olds of Lansing, March 23, 1887, but was returned 

 to the College on his learning of her possible condition. She produced a calf in 1888 

 and aborted in 1889. She was fattened and slaughtered for beef March 1, 1890. On 

 post-mortem examination the lungs and intestines were fpund badly affected with 

 tubercles. 



"Helianthus 5. — This animal had a swelling in the throat in the fall of 1889. During 

 the winter it grew worse and affected his breathing. He was separated from the 

 herd and ate well, but refused his drink. He discharged somewhat from the nostrils. 

 When slaughtered the thyroid gland was found to be badly affected with tuberculous 

 matter. The lungs and neighboring parts were also tuberculous. 



"Late in the fall of 1889, Miss Bates commenced to decline in health and failed 

 rapidly. For safety she was placed in the barn and it only hastened the decline. 

 She was slaughtered on December 7, 1899, and both lungs were found adherent to 

 her sides and nearly solid with tuberculous lesions. She was one of the worst cases 

 found. 



"College Morlej was slaughtered for beef November 9, 1899. He was in fine flesh, 

 but a large bunch on the left side of the neck, eight or nine inches in diameter, was 

 found to be of a tuberculous nature. The lungs were also affected with tubercles. 



"College Red Rose 5 also showed tuberculous lungs. 



"Hnow Bloom. — Growing very old, this cow was slaughtered for beef February 7, 

 1891. Post-mortem examination showed slight deposits of tuberculous matter in the 

 lungs. 



"Aaltje 2 had lost one-fourth of her udder and was fed for beef. On post-mortem 

 examination both lungs were found affected with small tubercles as well as some large 

 ones. 



"Louette appeared dull during the summer of 1890. She commenced coughing 

 and was attacked by a high fever of 105 degrees F. She was slaughtered October 17, 

 1890. Her right lung was almost solid from tuberculosis ; her left lung was badly 

 affected and also the liver. Her calf was slaughtered at the same time, but was found 

 apparently sound. 



"Fennel Duke 2nd of Sideview. — This bull, in the spring of 1890, was fed off and 

 slaughtered on April 25. He had not fed well for a year, although he had always 

 been a hard feeder. On post-mortem examination was revealed a tuberculous tumor 

 about the size of a walnut in the right lung, near the base, close to the pulmonary 

 glands. His cough, which he had previous to his slaughter, had probably been caused 

 by a tumor in the tracliea not of a tuberculous character." 



From Prof. Davenport's report, it is evident that tuberculosis was extensively 

 prevalent among the members of the College herd in the years 1889 and 1890. After 

 the slaughter of the above cattle we find no records of tuberculosis in the herd, 

 although we imdorstand from those connected with the College at that time that 

 there were grave suspicions of the disease existing. There is evidence of the persistency 

 of this disease after the slaughter of the above animals, found in the swine register. 



In March, 1891, a sow and boar were slaughtered and found to be tuberculous, by 

 Dr. Grange. May, 1891, four sows were slaughtered and found to be tuberculous. 

 In July of the same j'ejir, Dr. Grange post-mortemed four boars which were tuberculous. 



The data given thus far reveals a very deplorable condition among the animals of 

 the College farm during the early '90"s, for which at that time no one could have been 

 held responsible, because the tuberculin test was not yet knowni. The records do not 

 show whether the disease was completely wiped out at that time. It is probably a fair 

 inference to regard it as fairly checked in its worst stages, but by no means com- 

 pletely eradicated. What was left doubtless furnished the nucleus for the develop- 

 ments of 189G, when the herd was first tested with tuberculin. During the interveninc 

 time, between 1891 and 1890, the disease was slowly progressing, but in none of the 

 animals liad it reached such a stage as to manifest itself in any characteristic 

 symptoms. 



During the years 189.3, 1894 and 1805 the character of the herd was changed from 

 the beef to the dairy type, thus making it more essential that the tuberculin test be 

 applied to ascertain whether tuberculosis existed, although there was nothing especially
