A CONTINUOUS RECORD OF ATMOSPHERIC NUCLEATION.

The subsidence constant must be smaller in this case, since S s + 1 = sl 

 (i s2 +l /ysl), and it is clear that 5 and s 2 must change in the same ratio 

 nearly. It was shown that S [ = .TJS O , or s' = .595*, and hence 5 ; = 2.6X.59 

 = 1.56. An actual computation gave Si =1.3, the difference being easily 

 referable to incidental discrepancies. 



23. Remarks on the table and graphs. The green corona now shows the 

 nucleations (no, 000 + 82, ooo)/2 and independently 96,000, in the two series, 

 agreeing reasonably well with the above 85,000, 106,000, 104,000, 96,000, the
