The difficulty of obtaining reliable information in regard to cattle diseases is very 

 great. especially where t he eat t le are as healthy as those of the West. The condition

 standpoint, then, I can say with certainty that of all the animals examined not one 

 was affected with limy; plague. Thecattl'e in the markets are free from it, as a re t hose

REPORT BY A. J. MURRAY, M. R. C. V. S., DETROIT, MICH., TO THE 

 UNITED STATES TREASURY CATTLE COMMISSION. 



In accordance with the instructions received from the United States Cattle Com- 

 missioners at the time of receiving my appointment as inspector, I have examined, 



1st 



between the datesof 2d September and 31st December, 1881 1st, the lungs of a 

 number of cattle in the Detroit slaughter-houses ; 2d, the cattle yards in Detroit, 

 Toledo, and Grosse Isle; 3d, a number of cows and cow stables belonging to dairymen 

 in and near Detroit ; 4th, made what post-mortem examination was practicable of cows 

 dying in Detroit during the above period. 



EXAMINATION OF LUNGS. 



During the above period I have examined the Inugs of 3,876 cattle at the slaughter- 

 houses of Messrs. William Wreford, Jefferson avenue; John Robison, Michigan av- 

 enue; George Duff, Michigan avenue; Capells & Duff, Twentieth street ; Mclntyre 

 &. Robison, Twentieth street ; John Loosemore, Foundry street ; - Reid, Michi- 

 gan avenue ; William Voight, Saint Aubin street; John Rauss, Randolph street. 

 Of that number 2,082 cattle came from States lying to the west and southwest of 

 Michigan. In many instances I could not ascertain from what State the cattle whose 

 lungs I examined had come, but the greater number of them were raised in the States 

 of Illinois, Missouri, Kansas, Colorado, Iowa, and Texas; but other Western States 

 probably furnished a portion of the 2,082. Saint Louis is the point from which most 

 of the cattle brought from abroad to Detroit are shipped ; a few are sent from Chicago. 



Seventeen hundred and ninety -four of the cattle whose lungs were examined were 

 raised in the State of Michigan. A few whose lungs were examined, however, were 

 Indiana cattle, but I was unable to ascertain the exact number of cattle which had 

 been brought from that State. 



In the lungs of the 2,082 which may be termed western cattle, disease was found in 

 nine individuals. 



In seven cases the lungs of Texan cattle were found to be diseased. A section through 

 the center of the diseased part of the first lung showed the alteration produced by 

 intestinal pneumonia, but the diseased portion was not much overall inch in diameter. 

 and the nodule which the diseased part formed was about the size of a walnut. 



In another lung a small space about the size already mentioned was the seat of hem- 

 orrhagic infraction. The exuded material seemed to be liquifying and absorption to 

 be taking place. 



A somewhat similar area in another lung had undergone fibroid degeneration. 



In the fourth lung an area of about an inch and a half iu diameter was the seat of 

 fibrinous exudation. Six or seven small cavities about the size of, a bean were exposed 

 in making a section of the nodule. These cavities were filled with pus. 



In the fifth lung an area of similar size was in a state of cheesy degeneration. This 

 portion of lung was encysted, and calcareous degeneration was commencing in the 

 contents of the cyst. 



In each of these cases the seat of disease was the anterior portion of the lung, and 

 it seemed rather extraordinary that in each case the area of the disease should be so 

 small. 



In the sixth lung I found nearthe base an induration about the size of a moderate- 

 sized apple, which extended nearly from the internal to the external face of the lung.
