Effect of lapse of time on the nucleation of dust-free air impris- oned in the fog Chamber.—The 5-minute periods in the preceding table, or figure 18, do not markedly diminish the aperture of the coronas. Larger periods of waiting are very effective, as is seen in table 12, where v\ V shows the volume ratio of fog and vacuum chambers. The.
