Weather and the Ultra-violet Radiations of the Sun.

Abstract

I WAS rather astonished by Dr. Carl Ramsauer's second letter in NATURE of June 13, which has just reached me, and although “the weather of 1911” is rapidly becoming ancient history, and I have much reluctance in pursuing the discussion of it, it is hoped that the long distance which separates me from the editorial room will be sufficient apology for asking your indulgence at this late day in order to register a protest against the conclusions enunciated in that letter.
