By this method I found that 1 cc. of seawater (salinity 



35.l'j%o) absorbs at a tension of 760 mm. (dry pressure) of 

 carbonic acid 



at 0.0° 1.412 cubic centimeters 



G.4° 1.119 — — 



15.0° 0.8.53 — — 



24.1° 0.659 — — 



By means of these results the absorption-curve was con- 

 structed, and from this curve were the following values for the 

 absorption from one degree to another of temperature obtained 

 by graphical interpolation. 



If my figures are compared with those calculated by Ham- 

 berg from determinations of the absorption in solutions of pure 

 chloride of sodium, it will be seen that the similarity is remark- 

 ably perfect. 



For all ordinary purposes I do not think it necessary to 

 make allowance for the variation of the salinity unless it falls 

 below 32 %). The allowance for diminished salinities may be
