 small and normal coronas are obtained. Cf. figure 17. 



Dilution with benzol in the ratio of 1/100 is not apiiarently effective, though 

 it must be remembered that great difficulty is experienced in keeping hydro-cailxm 

 solvents pure. Even the influence of a complete absence of naphthalene is un- 

 certain. The benzol itself fuinishes al)out a.s many nuclei. 



The value of the ab.sorption velocity, /, is characteristic, in s[)itc of the 

 volatility of the solvent, the nuclei seem to be (juite indefinitely persistent. The 

 stronger solution corres[)onds to a somewhat smaller value of k than the diluted
