Object Statement

Weather forecasting device, metal, made by Negretti & Zambra, London, England, 1915

Physical Description

The weather forecasting is a circular device, made from brass and consisting of three concentric circles, which when rotated can assist in calculating the weather patterns. The outer and largest of the circles has two scales. The first for barometer readings at sea level in inches and the second for the wind direction, with "dead calm" being the centre. The second disk features three points with arrows, at regular intervals, for indicating a rising, falling or steady barometer reading. The inner and smallest disk displays the instructions of how to use the device, an arrowed section at the top pointing at the barometer readings scale and a cut out windowed section at the bottom for revealing the appropriate weather forecast printed on the slide below. The device also features a small circular hook at the top and a pop out stand, with two legs at the back.
