RESIDUAL WATER NUCLEI.

67. Data for vapor nuclei. Table 47 contains similar data for the 

 vapor nuclei of wet dust-free air. In series i and 2 large coronas or high 

 nucleations are met with at the start, and they are compared in fig. 

 34, c, with a corresponding case for ions. In series 3 and 4 lower initial 

 nucleations are contained, and these data are compared in fig. 34 with the 

 corresponding cases of ions and phosphorus nuclei. Corrections for 

 subsidence should have been added to the graphs for ions and for vapor 

 nuclei, but these are not large enough to modify them materially, so far 

 as the figures go. *Q

FIG. 35. Relative difference of nucleation (n' n) /n of water nuclei from fog particles 

 precipitated upon phosphorus nuclei and on ions, in terms of i/n. The serial number 

 of the initial nucleation is attached to each curve. 



68. Remarks on the tables. The graphs in figs. 34, a, to 34, c, show 

 unmistakably that the water nuclei obtained from the evaporation of 

 fog particles precipitated on ions vanish in the successive exhaustions 

 faster than in the corresponding case with the vapor nuclei of dust-free 

 air; while the water nuclei from fog particles precipitated on vapor 

 nuclei vanish much faster than is the case for the corresponding solu-
