DISEASES OF THE OX AND SHEEP. 265 



1'5°C. above the normal. It may quickly rise and reach its 

 highest point in from one to three days, and then sitik rather 

 rapidly to its ordinary level, and sometimes even below it. In 

 animals which are about to recover, the temperature is higher 

 during the fourth and fifth days, and diminishes on the sixth or 

 seventh, and even then much more slowly than in those animals 

 which will die. Moreover, if the temperature in the morning 

 is equal to that in the evening, or if it falls rapidly below the 

 normal point, the animal will die. 



With regard to the temperature on the surface of the body, it 

 is not equable. The horns, ears, and lower extremities of the 

 limbs may be either very cold or very hot. The muzzle, too, 

 varies in temperature, and it is generally a little moist. The 

 hair is dull and upright, especially along the spine, and the skin 

 is not supple. The animal quickly loses condition. The in- 

 crease of the general temperature is followed in about thirty 

 hours by a diminution in the quantity of milk secreted. 

 •Gradually the amount of milk diminishes, and towards death 

 the secretion of this fluid may be suppressed altogether. The 

 specific gravity of the milk is also diminished, and sometimes 

 the milk has a reddish colour at about the fourth day. Coin- 

 cidently with the first diminution in the secretion of the milk, 

 the alterations in the mucous membranes, the disturbance of the 

 functions of the nervous system, dry coughing, difficulty in 

 breathing, and loss of appetite are very quickly manifested. 

 Within about three days from the outset, the changes in the 

 lining membranes of the respiratory and alimentary tracts have 

 developed themselves, and in about five days they have reached 

 the most pronounced stage. Death may, however, take place at 

 the end of the first day succeeding the attack, the disease having 

 run a very rapid course. 



For those who desire detailed information respecting Cattle- 

 Plague, the work of John Gamgee, above mentioned, is recom- 

 mended, or Dr. Fleming's Manual of Veterinary Sanitary 

 Science and Police (1875). Those who wish to read up the 

 recent experiments are referred to the foreign scientific journals, 

 such as the Ceniralb. f. d. med. Wiss., No. 18, 1883, in which 

 they will find Seramer's investigation conducted in co-operation 

 with Archangelski. With regard to treatment, no veterinarian 

 would recommend that any should be tried, if the disease should
