[Feb. 16, 



daily allowance of 88 oz. free fluid (Table III.), will show that this pari- 

 passu increase and decrease in the perspiration and urine are by no means 

 uniform on going to or quitting the tropics, but oscillate considerably in all 

 latitudes, both in quantity and contained solids, even in adjacent days.

 voyage across the tropics of 34 days.
