ningsskaalen har en fri Overflade af 100 Kvadratcentime- 
ter, saaledes at en Kubikcentimeter Vand svarer til en 
Fordunstningshøjde af 0.1 Millimeter. Stetten er smalere 
end i det ældre Apparat og Bøjen er af cylindro-conisk 
Form. Fordunstningsskaalen er forholdsvis dybere, og paa 
Bunden af den ligger en Rust af tynde paa Højkant staa- 
ende Metalstriber, hvormed Hensigten er at hindre sterkere 
Bevægelser af Fordunstningsvandet fra at slynge Vandet 
ud over Skaalens Rand. Paa denne Rist ligger det indre 
Thermometer. Fordunstningsskaalen og Stetten ere fortin- 
The evaporating dish has a free surface measuring 100 
square centimetres, so that 1 cubic centimetre corresponds 
in height to 0.1 millimetre of evaporated water. The stem 
is narrower than that of the former apparatus, and the 
buoy cylindro-conical in form. The evaporating dish is 
relatively deeper, and has at the bottom a grating of thin 
metallic strips, the object of which is to prevent the water from 
being splashed over the brim of the dish by any sudden

tinned, and the buoy japanned. The outer vessel moves 
with greater freedom in the gimbals. The whole apparatus 
is enclosed in a square wooden box, and the upper opening 
between the outer vessel, swinging in gimbals, and the 
wooden box, is closed by a sheet-iron cover 00, that swings 
with the outer ring of the gimbals. A thin metal roof, 
provided with four water-tubes, resting on four slender iron 
pillars, covers the whole apparatus, and protects it from 
rain, soot, and other causes of injury. In this apparatus 
the temperature did not rise much above that of the air 
or the sea, and observations could be taken in comparatively
