Williams and Captain Seaman, of that place. The history of this out- 

 break may be summarized as follows: Hon. E. B. Hyde, of the State 

 Commission on Diseases of Domestic, Animals, first visited the farm of 

 Mr. Williams on August 8, and at that time found a young bull in the 

 lot partially recovered from an attack of disease, and a cow and an ox 

 were both very sick with what he considered to be the typical symptoms 

 of pleuro pneumonia. At Captain Seaman's a cow was very sick and 

 presented the same symptoms as were seen with the affected cattle be- 

 longing to Williams. 



The next morning Dr. Rice, of Hartford, was called, and on arrival, 

 Williams' cow was found to have died during the night. 



A post-mortem examination was made and the lung found attached to 

 the walls of the chest ; when cut across it was seen to be solidly hepatized, 

 of a marbled appearance, and presented all the characters of contagious 

 pleuro-pneumonia. The Commission advised slaughter, which was ob- 

 jected to, but the same day, after the departure of the State officers, the 

 sick ox belonging to Williams and the cow belonging to Seaman were 

 slaughtered. These animals were not examined professionally, but the 

 descriptions which I received from those who were present were suffi- 

 cient to satisfy me that the lungs were solidified and attached to the 

 ribs. 



August 29, I visited Mr. Williams' farm and learned from him the 

 particulars of the outbreak. The first symptoms of disease were seen 

 in one of the cows June 20, and a second cow was attacked on June 23 ; 

 both of these died from the effects of the disease July 3. At the time 

 of my visit, August 29, there were six animals on the place : one ox, 

 quite sick, with left lung solidified ; one Jersey cow, had been quite 

 sick but was now better; one young Jersey bull, with left lung solidi- 

 fied, and three Jersey cows, in which I found no evidence of disease. 

 Only one animal had been brought on the place within a year preoeding 

 the outbreak, and that was a Jersey cow named Mollie Lathrop 3d, 

 No. 7627. She was obtained by exchange with Charles Decline, of New 

 Durham, N. J., on April 10, 1883. This cow aborted the last of May, 

 but has shown no other signs of sickness. At the time of examination 

 she was in fine condition, fat, glossy, with no cough and no signs of 

 lung disease, revealed by either auscultation or percussion. 



I visited Charles Decline at New Durham, N. J., on August 30. He 

 stated to me that he exchanged cows with Williams about April 16. 

 His cow went to New London on the same boat that the other returned 

 by. According to the statement of Williams' farmer, the two cows were 

 together about a quarter of an hour at New London. The cow Decline 

 received from Williams sickened about the last of May. About a week 

 later she and another Jersey cow, which stood beside her, and which 

 was also sick, were killed and examined by his son, who is a veterinary 

 surgeon. Both were affected with lung disease, which he pronounced 

 to be pleuro-pneumonia. The lungs were hepatized, marbled in color, 

 and attached to the walls of the chest. 



Decline purchased Mollie 3d of Mr. Whiten ack, of Dunellen, N. J., 

 December 13, 1881. He says that he never had any disease among his 

 cattle until after the cow arrived from Connecticut, and attributes the 

 infection to her. 



It was evident that some of the facts connected with the history of 

 the disease in these two herds had been concealed, but it was very cer- 

 tain that the disease had existed in* both herds, and it was very proba- 

 ble that one of the herds had been infected as the result of the exchange 

 referred to above. Considering that there had been no disease in Con-
