Abstract
THE rains this year have been more persistent than usual. At Perpignan they have been extraordinary. Is it necessary to see any relation between this circumstance and the recent volcanic eruptions? The beautiful crepuscular colorations of the past autumn and winter have been attributed to these eruptions;. ought we also to attribute to them the extraordinary spring rains? I should be inclined to believe it. It is acknowledged that the presence in the atmosphere of solid particles facilitates the condensation of vapour. This would be in conformity with the position maintained by Mr. Aitken in his paper on Dust, Fog, and Clouds (volume for 1880–81, Trans. R.S.E.), He concludes thus:—“In an atmosphere saturated with vapour, but free from dust, there is formed neither cloud nor fog; whenever the vapour of water is condensed in the atmosphere, it is owing to the presence of those solid particles, each of which becomes, so to speak, a centre of condensation, or the nucleus of a small crystal of ice.”
