APPENDIX 



DENSITY OF CARBON DIOXIDE (CO.,). 1 

 Weight of ice. C0 2 in milligrams at 760 mm. barometric 

 pressure, and from io°-25° C. temperature. 



For every 10 mm. above or below 760 mm. 0.024 mg. can be 

 added to, or subtracted from, the weight given and a sufficiently 

 accurate result obtained. 



ABSORPTION OF C0 2 AND 2 BY WATER. 



One volume of water will absorb at atmospheric pressure the 

 following volumes of the two gases named, these being referred 

 to the density at o° and 760 mm. pressure.

 Atmospheric pressure at 760 mm. 3 



For every 10 mm. above or below 760 mm. 0.018 mg. may 

 be added or subtracted from the weight given and a sufficiently 

 accurate result obtained.
