The numbers used in the construction of this figure are also given in 

 table 3. 



o 1 2 s 4 5 6 7 8&\ _ Along with the quan- 

 tities previously con- 

 sidered this table also 

 gives, as in table 1, 

 under the column Y m 

 the average quantity of 

 water in kilograms con- 

 tained in the whole col- 

 umn of air of one square 

 meter section from the 

 ?m ground up to the al- 

 titude of the given 

 m pressure, while in the 

 last column under Y B 

 <m is given the number of 

 grams of water that 

 would be contained 

 1TTh therein if the air were 

 fully saturated for the 

 average distribution of 

 temperature (as shown by the curve / m ). 



The numbers collected in table 3 show clearly how the aqueous 

 vapor is distributed throughout the atmosphere above Germany.

By a little extrapolation we find that the column of air resting on 

 one square meter contains on the average only 16.5 kilograms of
