Plate 37.

STRATUS COMMUNIS.

Break up such a sheet of cloud by numerous meandering cracks, and round off the detached pieces so as to give them a more or less rounded or pyramidal section, and the cloud becomes strato-cumulus, typical representations of which are shown in Plates [38] and [39], which depict different parts of the same sky. In Plate [38] the camera was pointed due west, and in Plate [39] it was turned round to the north-west, so that the two views do not quite meet.
