The first reference to high temperatures within the Earth known to the writer is by J. B. Morin in 1619; there is no known reference to the matter in the works of Agricola. Boyle, in 1671, raised many of the questions discussed in recent work. Little interest was taken in underground temperatures during the 18th century. The subject was energetically pursued by Committees of the British Association in 1868–1883 and 1935–1939. Measurements were first made at sea in 1950. In spite of the existence of about 2000 measurements of heat flow, the temperatures deep within the Earth are still very uncertain. Observations of magnetic variations combined with the study of samples from Moholes may give better estimates.
