Table X. — Record of recovered pig Qji 



On September 21 pig 951 was thoroughly washed, first with soap and 

 water, then with compound cresol solution, and again with soap and 

 water, and was then transferred to a clean, disinfected pen. A sus- 

 ceptible pig. No. loii, was then placed in the pen with pig 951. The 

 two pigs were kept in the pen together from September 21 to October 19, 

 a period of four weeks, and during this time the pen check or control 

 remained perfectly normal. On October 19 the control pig, No. loii, 

 was removed and injected with virus blood to test its susceptibility; the 

 animal sickened as a result of the injection, was off its feed for a week, 

 and showed a marked temperature reaction, but recovered. 



In order to determine whether the virus was present in the blood of 

 pig 951, this animal was bled from the tail on October 6 and 5 c. c. of the 

 defibrinated blood were used for the injection of pig 1030. This animal 

 was kept under observation from October 6 to October 27, a period of 

 three weeks, and remained perfectly well. On October 27 it was injected 

 with 5 c. c. of virus blood to test its susceptibility and was killed for 

 virus eight days later, the autopsy showing characteristic hemorrhagic 

 lesions and ulceration of cecum. 



Experiment XII. — Pig 1046 was injected with 5 c. c. of urine from a 

 cholera-sick pig. No. 1032X, on October 13, and developed a typical, 

 acute case of hog cholera, but made a good recovery. This pig was one 

 of those used in the experiment to determine the infectiousness of the 

 blood, excreta, and secretions of cholera-infected pigs. Its record is
