The catalogues of mid-eighteenth-century mathematical instrument makers included not only instruments in the sense ‘tools of science’ but also devices intended primarily for educational use. Among the latter would be found mechanical models of the solar system, in varying degrees of complexity and under various names; for convenience such models may be, and often were, loosely called orreries.

Documentary evidence has recently been discovered in the Archives at Petworth House, West Sussex, for the setting up of a laboratory in the House at the end of the eighteenth century. This paper gives details of those involved in the setting up of the laboratory, and of their other scientific and cultural interests. The accounts from the suppliers of the laboratory equipment are transcribed, and a brief description given of the many pieces of equipment from the laboratory that still survive (...) at Petworth House.

SummaryRecent studies have confirmed the traditional attribution of the invention of the balance barometer to Sir Samuel Morland. Two contemporary references to a 1678 printed pamphlet describing the invention are known but no copy has been located. This paper prints a seventeenth century manuscript copy of Morland's description of his balance barometer. The commentary outlines Robert Hooke's role in the invention. Morland's analysis of the mode of action of the instrument is considered in the light of contemporary comprehension of the (...) barometric phenomennon. (shrink)
