From the inspection of the preceding tables it will be at once 

 apparent how very various the urine is both in its quantity and 

 specific gravity, even when the individual voiding it enjoys per- 

 fect health. 



The mean specific gravity of the urine passed during these 

 ten days is 1-013859. The lowest specific gravity is 10047, 

 and the highest, 1-0266. 



The mean quantity passed per day was 90*91 cubic inches, or 

 3-307 Ibs. avoirdupois. The least passed on any day was 58*15 

 cubic inches, or 2-133 Ibs. ; the greatest quantity was 133*37 cu- 

 bic inches, or 4*857 Ibs. 



The preceding tables do not tally well with the universally 

 received opinion that the heaviest urine is that which is passed on 

 getting up in the morning. This was not the case in any one of 

 the ten days contained in the tables. On the contrary, the light- 

 est urine passed on the 23d of September, the 1st October, and 

 the 2d of October was that of the morning, and on all the other 

 days, save one, the lightest urine was that passed between twelve 

 and four p. M. from four to eight hours after breakfast, but be- 

 fore dinner.* On the contrary, the heaviest urine was in one 

 case passed one hour after dinner, and generally from three and 

 a-half to five and a-half hours after a meal. 



I made a comparison between the liquid taken into the sto- 



* Breakfast was between eight and nine A. M. j dinner at four p. M., and tea 

 at six p. M. There was no supper.
