plague." Result stated to have been negative as far as the 

 muscles were concerned. Viscera not examined. 



Exp. 3. A Dutch heifer. First feeding, March 3rd, 1865. 

 Three subsequent feedings. Symptoms only slight. Slaugh- 

 tered April 4th, 1866. Result positive. Measles especially 

 numerous in the diaphragm, but all had undergone calcareous 

 degeneration. 



fl x p. 4. A calf. Fed May 27th, 1872, with ripe proglot- 

 tides. Marked symptoms set in on June 7th, which began to 

 abate on the 12th, and had nearly disappeared by the 20th of 

 the same month. The record of the post-mortem result has 

 been lost ; but the animal was infected. 



Exp. 5. A calf, which had been made the subject of a 

 " glanders experiment." First fed on Oct. 17th, 1872, and 

 thrice in the following year, Jan. 1st and llth, and March 8th. 

 No symptoms having appeared the animal was kept for six or 

 eight months after the last feeding. Seeming to be free from 

 disease of any kind, it was sold as a sound heifer. 



Exp. 6. A young heifer calf, of six months. Fed Oct. 18th, 

 1873, with the mature proglottides of a large beef tapeworm. 

 No symptoms. Slaughtered several months afterwards. Result 

 stated to have been negative. Unfortunately I was not present 

 at the autopsy. 



Exp. 7. A young heifer. First fed May 19th, 1874, with the 

 joints of a tapeworm, and again on June 12th. No apparent 

 ill effects resulted, but the animal died in October. At the 

 post-mortem examination, made by Prof. Simonds, no parasites 

 were observed. Subsequently I found calcareous specks in the 

 liver which proved to be degenerated measles. 



Exp. 8. A calf. Fed on or about March 24th, 1875, with 

 sexually mature joints. The calf was put to and remained 

 with a foster mother until it died from disease of the larynx on 

 the 15th of the following July. The animal was ill-treated by 

 its foster parent, and at the post-mortem I observed a larga 

 intercostal cicatrix, evidently the result of injury. In this case 

 I devoted several hours to the exploration of the muscles and 

 viscera. Not a trace of the Gysticercus bovis could be found in 

 the muscles or connective tissues, but the liver contained scores 

 of perfectly developed measles, besides hundreds of others in 

 various stages of calcareous degeneration. On comparing some 

 of the latter with those I had obtained from the preceding 

 experiment the pathological appearances were at once seen to be
