Hardcover, green coth spine lettered in gold over paper covered boards. T.e.g. 99pp. Illustrated with full page photographic plates. A series of lectures originally given in December of 1924 designed for a popular audience and free from technical detail and description, pertaining to the emerging science of Aerography, the description of the atmosphere, known to most today as meteorology. No former owner’s name, no book-plate, no underlining or marking, etc. A clean, square, well bound copy. Very good+.
