Weather Forecasts in England [PDF]
Nature, 1914 MR. MALLOCK'S position in the scientific world is one of distinction and his letters on the subject or weather forecasts in England, which appeared in NATURE of February 26 and June 4, can, accordingly, scarcely fail to be regarded by many who are unfamiliar with the circumstances as reflecting injuriously upon the department of the public service ...
