14 CONTAGIOUS DISEASES OF DOMESTICATED ANIMALS. 



The affected cows which I saw were native animals in good condition^ 

 They had excellent pastures to run on, and there was no local cause 

 whatever which could be suspected of producing this or any other 

 disease. Besides, the time of year was not oue in which acute lung* 

 diseases are seen among cattle. Nearly every one of the affected lungs- 

 which I saw when in this State showed the typical lesions of pleuro- 

 pneumonia so plainly that, according to the best authorities in the 

 veterinary profession the world over, any one of them would have been 

 sufficient to afford a safe basis for diagnosing the disease. 



Besides the herds infected by the contagion introduced with the lot 

 of cattle from Baltimore, six herds have been infected from other sources 

 since September, 1883. The following table shows the number exposed 

 in each of these and the number destroyed after showing symptoms of 

 the disease:

Dr. Rowland, an Inspector of this Department, stationed at Jersey City,^ 

 N. J., discovered during the summer of 1883 that animals affected with 

 pleuropneumonia were being shipped to New York from Hunterdon 

 County, New Jersey. An investigation was ordered by Dr. E. M. Hunt, 

 secretary of the New Jersey State board of health, and a number of 

 herds were found in Hunterdon County which had been for some time 

 affected with this disease. Owing to the fact that the owner of the 

 affected herds was a large cattle dealer who gathered up cheap animals 

 from various parts of New Jersey and Pennsylvania, and to the ad- 

 ditional fact thar the disease had been ui)on his [)reinises for an indeti- 

 iiiie time, the origin of the trouble could not be satisfactorily traced. 



The owners of the infected herds had resorted to inoculation to arrest 

 the progress of the disease, and it was said that all fresh animals which 

 arrived were speedily inoculated. In spite of this, however, the losses 

 were very heavy, though their full extent could not be ascertained. Dr. 

 Miller, who investigated the condition of these animals, November 1, 

 informed me that out of one herd, containing (K) head, L*L* had been lost ; 

 from another containing 05 head, 8 were known to have died, and 1 was 

 killed to obtain virus for inoculation ; from another, containing 46 head, 

 8 had died ; from a fourth, containing 70 head, 10 had died ; and from
