34 CONDENSATION OF VAPOR AS INDUCED BY NUCLEI AND IONS.

detect any detailed similarity in the two sets of results. Thus the maxi- 

 mum of nucleation on September 20 to 24 is in no way suggested by the 

 ionization. Both curves tend to descend toward the end of the month, 

 but this may be due to causes to which both are tributary. As such an 

 effect will appear again in the average results, it may be dismissed here. 

 Fig. 9 also contains the nucleations n osi5 for 0^/^ = 0.345 for com- 

 parison. Remarks may be made with reference to them similar to those 

 just stated. The enlarged scale admits of an easier comparison of 

 n 335 and n 345 , which hold for different hypotheses.
