488 LIQUID PARTS OF ANIMALS. 



and also in the saliva, sweat, and stools of diabetic patients. The 

 abnormal state of the digestive organs gives origin to the forma- 

 tion of this sugar. No medical treatment hitherto tried has been 

 capable of removing the disease. Animal food seems to dimi- 

 nish the thirst and urine by bringing on nausea. Opium palli- 

 ates but does not remove the disease. It is obvious from the 

 facts above stated that there is no want of urea in diabetic urine. 

 Hence it is very probable that the introduction of urea into the 

 stomach of diabetic patients, as has been proposed by some me- 

 dical men in France, would not contribute to remove the dis- 

 ease. 



11. Urine during cramp of the stomach. This urine was ex- 

 amined by M. L. Gmelin.* It was clear, brown in mass, but 

 yellow in thin layers. With muriatic acid it formed a brown 

 mixture, with much nitric acid a clear red mixture, with a small 

 quantity of that acid a violet- coloured precipitate. This preci- 

 pitate was chiefly uric acid. On standing twenty-four hours the 

 urine deposited a rose-red sediment. The urine contained uric 

 acid, purpuric acid, and altered choleic acid. 



12. Intoxicating urine. It has been long known that the Tar- 

 tars make an intoxicating liquor by infusing the Agaricus musca- 

 rius in koumiss, or fermented mare's milk ; and that the intoxi- 

 cating properties of this agaric pass into the urine of those who 

 have taken it into the stomach. Langsdorf, in his travels among 

 the KorcEken, has remarked that the urine is even more intoxi- 

 cating than the prepared koumiss itself. It is much sought af- 

 ter by other persons, who intoxicate themselves by drinking it 

 Indeed, such is the persistence of this intoxicating quality, that 

 urine voided by five or six individuals in succession still re- 

 tains it.f 



13. In certain cases females, and sometimes males, have been 

 observed to pass urine which had the appearance of milk. On 

 standing a cream was formed on its surface, and it was found to 

 contain a notable proportion of casein. :f 



14. Medical men have repeatedly made mention of blue urine, 

 deriving its colour from a blue substance held in suspension in 

 it, quite different from Prussian blue. Gornier and "? .Ions found 

 this blue colouring matter a little soluble in water. Neither 

 acids nor alkalies alter its colour ; but nitric acid destroys it.
