the vesicle with a ueedle, and the ends sealed in a spirit 

 lanij). These were placed in an ice chest in Dr. Smith's 

 laboratory, where they remained until the following Friday, 



Mr. C. A. Denncn, agent of the Cattle Bm-eau at Brigh- 

 ton, sent two cows over to Bussey Institution which were 

 bought November 19 ; also two small pigs, six or eight 

 weeks old. The cows were inoculated November 21 by 

 scarifying the gum under the upper lip with a lancet, and 

 rubbing in some of the lymph. One of the pigs was also 

 inoculated in the mouth and between the toes on one fore 

 foot ; the other pig was kept to be fed upon the milk of 

 the cows. These cows, after two or three days, developed 

 typical lesions of foot and mouth disease in their mouths ; 

 one cow also showed very slight signs between the divisions 

 of the fore foot. Xeither cow ever showed any eruptions 

 on the udder. They both had a very mild form of the dis- 

 ease, and in two or three weeks seemed to have fully re- 

 covered. December 11 the cows were killed, post mortem 

 only showing cicatrices in the mouths of both, where the 

 ulcers had been. In one there were a few ulcers still un- 

 healed. Unfortunatel}^ the pig that was inoculated died a 

 couple of days later ; post mortem made by Dr. Smith 

 showed it to have congestion of the lungs. As the pigs had 

 probably been kept in a warm place, and then put in a cold 

 barn, it is to be supposed the one that died must have taken 

 cold. The other pig was fed the milk from the cows until 

 he was killed, December 11, but never at any time showed 

 s}Tuptoms of the disease. 



These experiments were undertaken to furnish additional 

 proof, if any was needed, that the cows seen at Dedham 

 were suffering from foot and mouth disease ; and when the 

 diagnosis was confirmed by Dr. Pearson and Dr. Law, on 

 their arrival, these experiments were advanced far enough 

 to still further strengthen the diagnosis of foot and mouth 

 disease. 



Texas Fever. 



At the time of making the report to the State Board of 

 Agriculture, last July, I reported informally that an out- 

 break of Texas fever had just appeared in Wellesley. This
