REPOET ON THE COMPOSITION OF OCEAN-WATER.

penclently of my laboratory experiments. Thinking that of the several data of the analyses 
the relative volumes of oxygen and nitrogen (the values and n 2 ) were more exactly deter- 
mined than the absolute volumes of the two gases, I tabulated all the values n x found along 
with the corresponding observed temperatures ; and then, for easier comj)arison, reduced 
the several results to the nearest of the temperatures 0°, 5°, 10°, 15°, 20°, 25°, 30°, by

Column I. gives the number of the water analysed. 
Column II. its natural temperature, t 0 . 
Column III. the temperature t to which the value for n j found was reduced by 
means of Table IX. page 175. 
Column IV. the value for n x thus corrected.
