488 DISEASES OF TH K URINARY ORGATs'S. 



there seems little doubt ; that the portion resembling porter 

 was mingled with bloody subsequently and slowly trickling 

 from the kidney, appears probable; but why this should sud- 

 denly change, and become like whey, I must confess I do not 

 pretend to offer an explanation. 



HiEMATURIA. 



Hsematuria, or bloody urine, is a complaint every now and 

 then made to us. When such a case does present itself, our 

 grand aims must be, first, to find from what part the blood 

 issues ; secondly, to discover the cause of the hemorrhage. 

 Blood may either come away alone, and shew itself in its 

 pure form, by coagulation, or it may be discharged mixed 

 with the urine, and then either only in part or not at all 

 congeal. Under such circumstances, the urinary discharges 

 are generally scanty; but sometimes they are very frequent, 

 and troublesome as well. It may be difficult or impossible 

 to say v» here the blood is coming from ; whether from the 

 kidneys or the bladder, or from any of the passages. Ex- 

 amination both per rectum, and externally upon the loins, 

 and al)out the penis, may not go far to clear up this point: we 

 must, for the rest, be guided by the symptoms, and by what 

 account we can collect of the occasion or history of the malady. 

 It may proceed from inflammation, or from some disorganiza- 

 tion either of the kidneys or the bladder, or it may arise from 

 calculus : it is most likely to prove to be the result of some 

 sprain or blow, or some injury of the organs. In old horses 

 the disease 'is likely to prove the consequence of long-standing 

 chronic disease of the kidneys, brought into fresh action by 

 some severer or more straining work than usual. 



The Treatment must be entirely under the control of cir- 

 cumstances. Staling of blood may be — indeed generally 

 ought to be regarded as — a dangerous omen. Should in- 

 jury have produced it, we must keep our patient as quiet 

 and as free from all sources of disturbance and irritation as 

 possible, and medically treat the case as it shall seem to re- 

 quire. Should febrile t)r inflammatory symptoms arise, they
