CONTAGIOUS TYPHUS. 269 



deteriorated — hence the foundation for tubercular consump- 

 tion. Cows of some breeds are not selfish, for the more 

 they are fed, tlie more milk will they give. These are all 

 the claims which can justly be made in favor of the 

 hereditary cause of consumption in cows. 



Symptoms. Thin of flesh, unthrifty; a staring coat or 

 hair, long and dead-looking ; a low husky cough, loss of 

 appetite, weakness, and a bloodless condition of the whole 

 system, which is readily known by the pale, white look of 

 the lining of the eyes, nose, and moiith. The consumptive 

 cow stands with her back arched, and her fore legs turned 

 out at the elbows, and when lying rests on the belly 

 and breast bone. The milk of such cows is thin, blue, 

 and watery. 



Previous to the death of a consumptive cow, diarrhoea, 

 dysentery, discharges from the nose and eyes, accompanied 

 with hectic, or sympathetic fever, conclude the symptoms 

 of this lingering, but fatal disease. 



Treatment. In the early stage of consumption in cows 

 much can be done in the way of treatment. Feed the 

 animal well with rich and nutritious material, such as lin- 

 seed, cake meal, etc. Sulphuric acid given several times a 

 week, in doses of half an ounce in weight, largely diluted 

 with water, will sustain the vital powers, and impart 

 tenacity to the buccal membrane throughout the body. 

 Use occasional doses of sulphate of iron and gentian ; three 

 drachms of iron and half an ounce of the gentian, will 

 make one dose. Such treatment will prolong the life, and, 

 at the same time, improve the condition and milking qual- 

 ities of the cow.
