STANDARDIZATION AND EFFICIENCY OF THE FOG CHAMBER. 2Q 



TABLE n. Standardization of fog chamber Continued. 



All the results shown in table 1 1 have been constructed graphically in 

 figs. 8 and 9 for parts V and VI of the tables, respectively. The observed 

 and computed apertures 5 are first given ; then the observed or optically 

 computed d' ', and the computed d from sequences appear, and finally the 

 observed or optic n f and the computed nucleation n from sequences. 

 The corresponding data coincide very closely after nine or eleven ex- 

 haustions, i. e., for moderately small and small coronas; but in the case 

 of large coronas and nucleations there is marked systematic divergence. 

 A discussion of these results will be given presently.
