Ozone

Abstract

WILL you please allow me to make a suggestion concerning an additional element of observation at climatological stations? I refer to the observing of ozone. As the salubrity of a district to a great extent depends on this powerful factor, would it not be well to include ozone in climatological observations, especially in the case of hill and valley stations? The tests would, I think, at least enable some conclusions to be drawn as to the purity and salubrity of the atmosphere at the different health resorts, and in my opinion present means, even though imperfect, should on no account be neglected until better are found. They might be exposed on a hook in Stevenson's thermometer screen, as recommended by Mr. Buchan; but I find that this plan is only of service during dry weather, and I think Clarke's ozone cage is preferable.
