MR. L. C. W. BONACINA'S paper entitled "Landscape Meteorology and its Reflection in Art and Literature" (Quart. J. Roy. Meteor. Soc., 65, No. 282; October 1939) is a detailed study of the scenic aspect of clouds and weather, and an example of that co-operation between science and art which is one of the most interesting developments of culture during recent years. We welcome particularly the author's dictum that it is a mistake for the man of science to regard scenic values as altogether outside his province. It is equally to the point that the landscape artist will find additional enjoyment, and possibly also increased efficiency, if he studies the physics of meteorological effects. The later part of the paper is mainly devoted to descriptions of local and seasonal phenomena. One outstanding example is that of the night sky as seen from the high plateau of Bolivia, where the general aspect of the constellations is that of coloured stars.
