by CLARE, Martin.
London:: Edward Symon, 1737., 1737. 8vo. xvi, 369,  pp. 9 engraved plates, index, errata. Contemporary crimson gilt-tooled calf, later gilt-stamped leather spine label, raised bands, all edges gilt. Ownership inscription of D. Laing. SPECIALLY BOUND DEDICATEE'S PERSONAL COPY. Very good. Second edition, corrected and improved. The contents are made up on 67 chapters relating to statics, hydrostatics, syphons, pumps of various types, "fire-engines" [steam engines], motion of water in canals & pipes, specific gravity, hydrometer, pneumatics, barometer, air-pump, effects of air pressure on animal bodies, muscular motion, heart pressure, circulation of the blood, animal respiration & suction, elasticity of the air, cupping (bleeding), rise of sap in plants, thermometer, hygrometer, atmospheric phenomena, of winds, smokey chambers, causes of thunder & meteors, precipitation, and the origin of springs, sound (the trumpet instrument), and tides. – Roberts & Trent. / Indeed, the chapter on "The Art of Diving" makes clear the effect of increasing pressure as it affects the volume of a given amount of gas (Boyle's Law). Indeed, the relative volumes of air at 33, 66 and 99 feel (1, 2, and 3 atmospheres) are explicitly defined. This chapter, however, discusses the malady that we now know as Caisson's Disease or the Bends, but fails to explain the reason behind the resulting debility. The plates mostly deal with hydraulics, including siphons, water wells and decorative fountains. The author was apparently quite well known in his time as Benjamin Franklin cites Clare and this book in his own writings. Martin Clare was a London schoolmaster and Freemason. He … 'entertained' the members of the Grand Stewards' Lodge on 17 November 1735 with …an excellent Discourse containing some maxims and Advice that concerned the Society in general. Clare's grave and quiet method of delivery made a strong impression on the audience and [his] conclusion was received with loud approbation… [Stewart]. / Dr. Nicholas Hans (1888-1969), a renowned scholar of comparative education, writes that Clare founded the Academy in Soho Square, London, in 1717/18. On the title of this imprint Clare claims the degree "A.M." [Master of Arts], and in 1720 he was titled School-Master in Soho Square, interested in vocational training for boys. "In consequence the subjects taught in his school included (in Clare's order): Latin, English, French, Writing, Arithmetic, Book-keeping, Drawing, Geography, Mathematics (Mensuration, Gauging, Surveying, Navigation), Geometry, Astronomy, Experimental and Natural Philosophy and Algebra. In 1735 Clare published his well-known book on the Motion of Fluids. The copy in the British Museum gives some additional information about Clare. On the covering leaf there is a handwritten note, evidently by a contemporary, which states that when Clare was 'standing candidate for election into the Royal Society, it was objected that he sought that title to give a sanction to his profession of instructing Youth and to this productions: whereupon he declared that he would not make any public use of the said title'. He was duly elected F.R.S. and appeared in the List for the first time in 1736. He dedicated his book on fluids to Thomas Thynne, Viscount Weymouth, the Grand Master of the Ancient and Honourable Society of Free and Accepted Masons. Clare calls Thynne 'the patron and encourager of useful arts. . . Clare himself was a freemason. . . From the introduction to his book on fluids we see that Clare was a friend of Dr. Th. Desaguliers, the famous leader of Freemasonry and a pioneer of adult education. Clare says that he consulted Desaguliers on some points in the book, which was the result of a series of lectures to private audiences." – Nicholas Hans, New Trends in Education in the Eighteenth Century, Routledge, (1998).
