receive a pound of epsom salts and a pound of table salt in a 

 drench, when changed to the new pasture. This treatment will 

 effectually stamp out the disease in a few days' time. 



PosT-MoRTEM. — The post-mortem revealed the fecal matter 

 in the reticulum dry and caked to the mucous membrane, the 

 bladder distended with dark or purple colored urine. This dis- 

 ease resembles Texan fever and anthrax, but it is not the same 

 disease, as is generally supposed. It is no doubt due to the effects 

 of climate and the condition of pastures and water. 



TUBEECULOSIS. 



This disease is commonly known as consumption, and is due 

 to a vegetable parasite, the bacillus tuberculosis. It affects man 

 and all other animals, but is much more prevalent in cattle. In 

 1882 Koch announced his discovery of the bacillus or germ of 

 tuberculosis, and was the first to demonstrate, by a special pro- 

 cess of staining, the constant presence of the peculiar bacilli in 

 cases of acute tuberculosis. The bacillus is a small, rod-shaped 

 organism from one seven-thousandth to one ten-thousandth of an 

 inch long, and one-tenth as broad. They are usually straight, but 

 may be curved. They occur singly, but sometimes by pairs. 

 Multiplication is very slow, and takes place by division, by spore 

 formation. They multiply only in the body of man and other 

 animals. They cannot multiply external to the body, but can 

 live and retain their virulence, external to the body, for forty- 

 three days in putrid sputum, and one hundred and sixty days in 

 the dry state. The bacillus enters the body through wounds or 

 broken skin. The mucous membrane, pulmonary and diges'tive, 

 affords passage, and is the most frequent mode of entry. In the 

 former, the germs are inhaled in the form of dust; in the latter, 

 they are taken in the alimentary canal by infected milk or meat. 

 Having found a spot in which it can grow, the 'bacillus proceeds 

 to multiply. Most bacilli are taken up by cells, which enlarge 

 into giant cells and become the centers of typical tuberculosis. 

 Their presence excites more or less inflammation, and cassation
