TREATMENT. 327 



made to move at a faster pace than natural, there was want of 

 control over the posterior extremities ; he was inclined to keep 

 his head unnaturally low, Avas duller than he used formerly to 

 be, Avhile at times, on carefully watching him, he seemed to 

 become drowsy, as if coma might be developed ; there was 

 dilatation of the pupils, but perfect sensibility to the action 

 of light. The urine, to which attention was drawn, was 

 voided frequently, and in largely increased amount. When 

 examined in bulk, and as voided, it was muddy, opaque, 

 and slightly fragrant ; when allowed to remain at rest for some 

 hours, there was a deposit of about 20 per cent, of its bulk of 

 a gelatinous and finely granular-looking material, which, ex- 

 amined more closely, seemed made up chiefly of amorphous 

 granular matter, some cells, and renal casts. The urine was 

 examined chemically by Professor Dewar, who stated, that 

 although unable to obtain sufficient evidence of the existence 

 of sugar, there was undoubtedly present in the secretion some 

 peculiar material which acted towards reagents in a manner 

 precisely similar to sugar. During the time this animal was 

 under observation — nearly three months — the symptoms varied 

 somewhat, particularly those connected with the amount and 

 character of the urine, which, when least opaque and small in 

 amount, was always accompanied with decrease in the desire 

 for liquids. The evidence of disturbed nerve-power, and of 

 true cerebral disease, indicated by want of control over the 

 movements of the hind-limbs, the partial somnolency, and the 

 inabiHty to elevate the head without inducing an approach to 

 syncope, became more manifest for some weeks, after which 

 they were stationary, or rather suffered some decline. I had 

 not an opportunity of watching this case to its termination, the 

 owner parting with the animal, and it being removed from the 

 district. During the three months this horse was under ob- 

 servation he was at no time perfectly free from symptoms of 

 ill health, neither was he unfit to perform light work.
