HJHMORRHAGIES. 307 



puts on different appearances. If the blood poured out in the 

 kidney has happened to stagnate for some time in the uroters 

 or bladder, it is sometimes coagulated, and the coagulated part 

 is afterwards broken down into a grumous mass of a black or 

 dark colour, and therefore gives the same colour to the urine 

 voided ; or, if the quantity of broken down blood is small, it 

 gives only a brownish colour to the urine resembling coffee. It 

 sometimes also happens, that the blood stagnating and coagu- 

 lating in the ureters takes the form of these vessels, and is 

 therefore voided under the appearance of a worm ; and if the 

 coagulated blood happens to have, as it may sometimes have, 

 the gluten separated from the red globules, these worm-like ap- 

 pearances have their external surface whitish, and the whole 

 seemingly forming a tube containing a red liquor. I have 

 sometimes observed the blood which had seemingly been coagu- 

 lated in the ureter, come away in an almost dry state, resembling 

 the half-burnt wick of a candle. 



MXXXVII. These are the several appearances of the blood 

 voided in the Haematuria calculosa, when it proceeds especially 

 from the kidneys or ureter ; and many of the same appearances 

 are observed when the blood proceeds only from the bladder 

 when a stone is lodged there ; but the attending symptoms will 

 commonly point out the different seat of the disease. 



In one case, when a quantity of blood from the kidney or 

 ureter is coagulated in the bladder, and is therefore difficultly 

 thrown out from this, the pain and uneasiness on such an oc- 

 casion may appear chiefly to be in the bladder, though it con- 

 tains no stone ; but the antecedent symptoms will commonly dis- 

 cover the nature of the disease. 



MXXXVIII. In any of the cases of the Haematuria calcu- 

 losa, it will hardly be necessary to employ the remedies suited 

 to an active haemorrhagy. It will be proper only to employ the 

 regimen fit for moderating hoemorrhagy in general, and partic- 

 ularly here to avoid every thing or circumstance that might ir- 

 ritate the kidneys or ureters. Of such cases of irritation, there 

 is none more frequent or more considerable, than the presence 

 of hardened faeces in the colon ; and these therefore are to be 

 frequently removed, by the frequent use of general laxatives.
