Caption: Metalline thermometer. 18th-century journal page illustrating a metalline thermometer proposed by Keane Fitzgerald (died 1782). This device used the expansion of coiled strips of metal to monitor temperature. This principle is used in bi-metallic strips and thermostat sensor coils. This page is from volume 51 (1759-60) of the journal 'Philosophical Transactions', published by the Royal Society of London. Fitzgerald, who was living in London at the time, was elected a Fellow of the Royal Society in 1756.
