Cloud study by Luke Howard, c1803-1811: Cumulus and developing nimbus, preparatory to rain. Blue and grey wash with white, 19x27cm (recto); Cumulus developing cirrus. Grey wash (verso) Part of a collection of 51 drawings with 1 engraving, studies of clouds c1803-1811, by the meteorologist Luke Howard FRS (1772-1864). Mainly pencil and wash, 19x28cm. or smaller with conservation paper backs or edging. - Collection assembled in 1923 by Howard's granddaughter Mariabella Fry from 'loose scraps among family papers, without note or comment' and subsequently deposited by the Royal Meteorological Society. - Some sketches are inscribed, only two dated. Showing observations of cloud formations while adopting the nomenclature presented in Howard's paper 'On the modifications of clouds' 1803. Six drawings have highly finished landscapes probably by an assistant, Silvanus Bevan. Some are originals for engravings of cloud formations in editions of the classification promulgated in Philosophical Magazine 1803, Rees's Cyclopedia and other, later publications. For specific details of each drawing please see 1981-862/1 to 1981-862/52.

Part of a collection of 51 drawings with 1 engraving, studies of clouds c1803-1811, by Luke Howard (1772-1864), the first to develop a successful classification of clouds, thought too changeable to be brought into a scientific system. He presented is system in an 1802 lecture to the Askesian Society, in London.
