476 LIQUID PARTS OF ANIMALS. 



14. Urine N, from 86 to to 89 inclusive, from a boy of 8 

 years, of a good constitution, and a sanguine temperament, con- 

 fined to bed for a phymosis. 



15. Urine O, from 90 to 92 inclusive, from an infant of 3 

 years, a robust constitution, and a sanguine temperament. 



16. Urine P, No. 93, from a child of 4 years, of a good size, 

 and a lymphatic temperament. 



17. The whole of the urine voided by the children O and P 

 could not be collected. M. Lecanu conceives that the half of it 

 was lost. 



18. The temperature at which the specific gravity of the urine 

 was taken varied from 68 to 46, but most commonly it was be- 

 tween 50 and 60. 



19. The greatest quantity of urine voided in twenty-four hours 

 was No. 33. It amounted to 60575 grains, or 8-65 pounds avoir- 

 dupois, but in four days the quantity was reduced to 31452 

 grains, or 4-49 pounds avoirdupois. The smallest quantity[(ex- 

 cept that of infants) was No. 73, 8257 grains, or 1-18 pounds, 

 voided by a woman of 43 years of age. 



20. The highest specific gravity was 1*0386, and the lowest, 

 1-0100. 



MM. Cap and Henri are of opinion that urea exists in urine 

 in the state of lactate of urea, and they have shown by experi- 

 ments, which appear conclusive, that healthy urine actually con- 

 tains lactate of urea.* But it would be difficult to prove that all 

 the urea in healthy urine is in the state of lactate. 



Dr Alfred Becquerel f has lately analyzed a great number of 

 urines, both from individuals in health and disease. The follow- 

 ing table exhibits the mean quantity, the specific gravity, and the 

 relative constituents of healthy urine deduced from the analysis 

 of the urine of eight healthy individuals, four males, and four fe- 

 males : 



In males. In females.
