12 CONTAGIOUS DISEASES OF DOMESTICATED ANIMALS. 



coininoii source, rather than that one contracted the disea'^e from the 

 other. 



A second visit was made to the farm September 7, in company with 

 Hon. E, II. Hyde and T. S. Gold, of the State Commission on Diseases 

 of Animals, and Doctors Thayer, Rice, and Parkinson. At this time the 

 bull and ox still presented symptoms of pleuropneumonia. The cow, 

 Mollie 3rd, was again carefully" examined and showed a rather large 

 area of dullness over the region of the heart and another low down 

 on the right side. My own opinion was that this dullness did not indi- 

 cate any disease of the lungs, though some of the others thought dif- 

 ferently. It was admitted by all, however, that there were no i)ositive 

 signs of diseased lungs in her case. 



A third visit was made, in company with the same gentlemen, with 

 the exception of Dr. Thayer, September 12, when the ox mentioned 

 above was slaughtered and examined. This animal was now believed 

 by the owner to have recovered. The autopsy revealed the left lung-; 

 solidly attached over a large surface to the thoracic wall and dia- 

 phragm. One-third of the organ was encysted and beginning to disin- 

 tegrate, another third showed more recent hepatization and was not 

 yet encysted. A section showed the characteristic marbled appearance^ 

 and the difl'erence in the age of the inflammatory process in various 

 parts of the lung. 



Members of the State Commission have since informed me that the 

 bull continued to fail and was destroyed by the owner on the 27th of 

 October. Before this, however, the Commission was called September 

 18 to see a new case of the disease, which had developed on the farm 

 of Amos Williams, the second neighbor south from the originally in- 

 fected premises. This was a cow, which presented the typical symp- 

 toms and ])ost mortem appearances of pleuro-pneumonia, having been 

 condemned and killed by the Commission. 



To recapitulate : H. E. Williams had seven animals affected out of his 

 lierd of nine by the introduction of the cow from Kew Jersey, which 

 animal was so slightly diseased as never to attract attention. Of the 

 seven sick ones three died of the disease. Two of those slaughtered 

 probably could not have recovered ; one of the slaughtered oxen was^ 

 improving, while the remaining cow was ver^^ sick when I last saw her. 

 The adjoining farm on the north and the second one on the south each 

 lost one animal from the disease. There were, consequently, nine ani- 

 mals affected in this outbreak. 



PENNSYLVANIA. 



October 3 and 4 I visited Chester County, Pennsylvania, in company 

 with Mr. T. J. Edge, special agent of the gov^ernor, and Dr. Bridge, State 

 Veterinarian. On the farm of W. P. Thomas I witnessed the slaughter 

 of 3 cows, and on the farm of J. H. Garret I saw 5 others killed, 

 these having been condemned by the State authorities as affected with
