Abstract
IN his letter to NATURE of February 6, 1926, p. 199, Mr. C. J. P. Cave has directed attention to the fact that well-defined cirrus clouds may occur at a much lower level than we generally assume to them, say, under a sheet of alto-cumulus. To support his view he describes a striking observation similar to that made by me on Sunday, June 13, at Strasbourg. During the morning and early afternoon of that day the weather was rainy and the sky covered with altostratus and nimbus. The nimbus ceased about 16.30 (G.M.T.) and the alto-stratus merged gradually into a sheet of fleecy alto-cumulus moving from west-south-west. It had a straight edge separating it from a beautiful clear sky.
