Drawing, 'Atmismometer' [Evaporometer], by Charles Kite Line drawing, figure 3 illustrating Kite's paper 'A Register of the Barometer, Thermometer, Hygrometer...& appearance of the Sky, at Gravesend in Kent. For the years 1787 & 1788'. The accompanying text [p.16] states that: 'The Evaporation which takes place from a surface of water is determined by the following instrument. (aa) Fig III is a vessel of copper, the surface of which is exactly 100 square inches, & is about 2 inches deep. (bb) is a strong glass tube, about 20, or 25 inches long, & its bore of such a rise that one cubic inch of water, occupies about one inch of its length. (c) is a copper vessel capable of containing about 3 pints of water. (d e & f) are corks.' In a footnote, Kite writes that 'This instrument might not improperly be called an Atmismometer'.
