affected with black-quarter. Other preventives now recommended 

 are the inoculation of the young animals with preparations made from 

 the diseased parts of an affected beast, injected direct into the blood, 

 through the walls of the jugular vein, which has to be dissected out for 

 this purpose, or to inoculate the young stock with black-leg vaccine, 

 which is introduced under the skin by means of a special instru- 

 ment. The preparations are very delicate, and have to be repeated, 

 and I fail to see how it can be an improvement on the old seton, with 

 the facts before named within my own experience of nearly sixty 

 years. The best plan, however, is to keep the animals indoors 

 until they are twelve months old, giving them good lodgings, dry 

 beds, good drainage, and nutritious food, such as linseed cake, 

 crushed oats and bran, with a little salt. Were this treatment 

 followed out, very little, if any, black-quarter would be seen.

 very short time. The noticeable symptoms consist of elevated 

 temperature, quick breathing, pulse scarcely perceptible, watery 

 discharge from the mouth and nostrils, drooping head and ears,

 an imported one ; happily, however, it has not visited our shores for 

 some time. Anyone wishing for further particulars and details 

 respecting this disease should refer to the revised ninth edition of 

 Williams's ' Principles and Practice of Veterinary Medicine.' 



463. Foot and Mouth Disease, or Murrain. — A contagious, 

 eruptive, vesicular, febrile disease, in which the mouth, feet, and 

 udder are affected, with, at first, small eruptive vesicles, which after- 

 wards burst and form ulcerating sores. The bacilli the cause have 

 just lately been discovered by Dr. Siegel. Some cases are of a more 

 acute nature than others ; and, again, we may have the mouth 

 attacked and the feet free, and vice versa. It affects cattle, sheep,
