DIABETES INSIPIDUS, 451 



astringents, the bromide of potassium, as well as the iodine treat- 

 ment, and have seen no permanent benefit from any of them. 

 Both iodine, or iodide of potassium, and the bromide moderate 

 the symptoms for a time, but usually the benefit has been of 

 short duration — a cough has come on, rajDid emaciation, decay, 

 and death. 



Post onortem apjjearances. — Both in horses and dogs, pallor of 

 the organs and tissues of the body generally ; in dogs, enlarge- 

 ment of the liver and caseous tumours in the lungs — the latter 

 being probably accidental complications. 



AZOTUKIA. 



Under the term of azoturia, or nitrogenous urine, I intend to 

 describe a disease to which attention was drawn in this country 

 by Haycock, Avho named it, at the suggestion of ]Mr. James 

 Moore, V.S., London, " Hysteria." In Gamgee's Domestic

The symptoms are well described by Haycock, who says — 

 " In all cases of this nature which I have treated the disease 

 commenced very suddenly. They [the subjects thereof] began to 

 exhibit an unusual degree of restlessness, to perspire profusely, 

 which symptoms or states were speedily succeeded by a dis- 

 position to lie down; by great sluggishness, loss of motor power 

 in the hind limbs; violent spasm of the large muscles of the 

 loins and hind quarters (the gluteal muscles were excessively 

 cramped), and the shoulders ; the pulse in two of them rose from 

 sixty to eighty beats per minute, and the respirations were 

 greatly increased ; they made several efibrts to rise upon their 

 feet, but from the total loss of all motor power in the hind limbs, 

 they were unable to do so ; two out of the three every now and 

 then strained violently, and ejected, j?c7' vaginam, excessive 

 quantities of coffee-coloured urine, which consisted principally
