Plate 32.
ALTO-STRATO-CUMULUS.
Alto-cumulus castellatus, which is breaking up and disappearing, is shown in Plate [33]. It was photographed with a long-focus lens, so that the scale of representation is about eight times as great as that of Plate [27]. This view was taken at Exeter while a thunderstorm was in progress at Bristol.
