THE URINE. 



stated somewhat differently by the different chemists who have 

 analyzed it ; but many of the differences are not important, 

 and the well-known accuracy of the several chemists renders 

 it almost immaterial which of the analyses is adopted. The 

 analyses by A. Becquerel being adopted by Dr. Prout, and 

 by Dr. Golding Bird, will be here employed. (Table I.) 



Table II has been compiled from the observations of Dr. 

 Parkes, and of numerous other authors quoted in his admira- 

 ble work on the urine.
