46 Remarks on Urine. 



In the latter case the urine will be of a deeper brown colour^ 

 and often blark, and its smell will be as foetid as the urine 

 of a person in good health which has been allowed to stand 

 ^ long time, especially if in a warm exposure. If the urine, 

 then, at the moment of evacuation, has already acquired a 

 fcetid smell, and if the colour of it is dark brown, it may 

 be safelv concluded that the humours of the body are ex- 

 tremely soluble, and have a tendency to puliefaction. 



If, bv accident, any one of the constituent parts of the 

 humours is' augmented; if the secretion of a part of them^ 

 which, being hurtful or useless to the body, ought to be se- 

 parated from it, is arrested, — for example, the secretion of 

 sweat ; or if the humours destined for other functions (bile 

 for instance) enter into the blood, it follows necessarily that 

 the quantity of the constituent parts of the blood, and of 

 course of the urine also, will be changed : and thus the urine 

 will take other colours and other qualities. 



Thus when perspiration is suppressed, at least if the 

 matter which should be exuded does not recoil into another 

 channel, the consequence will be an abundant discharge of 

 clear and limpid urine. 



If bile be mixed with the blood, supposing the bile to be 

 in a good state the urine will become saffron yellow : if it 

 be corrupted, the urine w ill become green or black. 



If the urine is turbid, or of a clear brown, it indicates that 

 the functions of the body are disturbed, and that secretion 

 cannot be made in the proper manner. This urine, because 

 it has a resemblance to those of certain animals, is called 

 urina jumentosa. 



The urine of itself never proves any thing positively : other 

 circumstances of the malady must confirm the presumptions 

 which the appearance of the urine had enabled us to form ', 

 and it is very wrong to examine first the urine, and the 

 other symptoms of the disease afterwards. If the physician 

 takes the uncertain signs of the urine as certain prognostics 

 of the disorder, the patient may, in his turn, regard that as 

 a certain sign of the ignorance of his physician. 



To prove what I advance, I shall only cite an example. 

 Black urine indicates corrupted bile ; or with one who has 



strained
