i8o Blood Diseases. 



where the skin is thin ; and the mucous membranes show 

 numerous mulberry red-looking spots, which, in common 

 with others on the skin, at a later stage favour the escape 

 of blood. The swellings eventually run into each other, the 

 skin cracks, and discharges of a yellowish colour flow 

 out ; then portions of the skin die and slough off, leaving 

 large open ulcers, which do not heal, or at least, not 

 without great tardiness. Sometimes the disease lingers 

 for months in the same creature ; hopeful signs occur 

 after the fourth or fifth day in milder cases. 



Treatment — Laxatives or Aperients No. i, with which 

 nitrous ether may be prescribed. Subsequently nitrous 

 ether and tincture of steel. Vegetable tonics, &c, are 

 indispensable, with small quantities of nutritious food, 

 fresh air, and perfect nursing. Subcutaneous Injections, 

 No. 10. 



Azoturia, sometimes known as Nitrogenous Urine, 

 Hysteria, and Albuminuria. — A blood disease dependent 

 upon a large quantity of nitrogenous elements in circula- 

 tion, producing impairment of the nervous system, con- 

 vulsions, and death in a few hours. It is common in 

 this country to horses and mares of the heavier breeds ; 

 sporadic, non-contagious, but communicating septic 

 disease to others by means of inoculation. The attacks 

 are sudden, and confined to the animals in best condi- 

 tion. They are first uneasy, violent colic shortly coming 

 on ; the pulse and respiration are greatly disturbed, 

 spasm affects the whole muscular system, especially the 

 loins, and these signs are intensified by the inability to 

 discharge urine. If unrelieved, large swellings occur 

 over the hips and loins ; general disturbance becomes 

 intense, stiffness rapidly follows, and ends in paralysis ; 

 convulsions are frequent, followed by coma and death. 



Recovery is denoted by an early and copious discharge 

 of urine, which resembles boiled linseed oil, having a 

 disagreeable odour, and liable to early decomposition. 

 All other signs now rapidly subside, and the animal is 

 soon convalescent. 



The causes are heavy feeding on rich food during very 

 light and irregular work, or enforced idleness,
