A CONTINUOUS RECORD OF ATMOSPHERIC NUCLEATION.

region of lower cusps is between n = 35,000 and 45,000, and of the upper cusps 

 between m = 95,000 and 105,000, or at 5 = 4.5 ^"^1 5 = 6.0 in the two eases. These 

 cusps mark the region of "green" coronas. The angular radius is (p = Ar° 18' 

 and ^ = 5° 44', respectively. Other remarks already made apply here.

 here, as the temperatvire is lower. Since 0=15.5°,

d = -^6m/ Tin= .02071 ' 



Hence the edge of the cube containing one fog particle is just 50 times the 

 diameter of the particle for the uniform conditions of condensation selected. 



The curves for d" (smooth hyperbola since d"s = consX.) and d are drawn 

 in relation to 5 as usual, and the latter give evidence of three or more cusps 

 with intervening minima. These in their maximum and minimum relations 

 are reciprocal with the corresponding curves for n. Both curves agree with 

 each other and with the preceding set for d. 



Horizontal positions are naturally better than vertical positions because of
