  1. “International Atlas of Clouds” (Atlas International des Nuages). Hildebrandsson, Riggenbach, and Teisserenc de Bort. Paris. 1896. This is the atlas referred to in the text. The letter-press is short, and is repeated in English, French, and German. 2. “Annals of the Astronomical Observatory of Harvard College.” Vol. XXX. Observations made at the Blue Hill Meteorological Observatory. Part III. Measurement of Cloud Heights and Velocities. By H. H. Clayton and S. P. Fergusson. Part IV.
