An experimental enquiry concerning the natural powers of water and wind to turn mills, and other machines, depending on a circular motion. 2 Teile in 1 Band.
London, 1760. - (23 x 17 cm). 77 S. Mit 3 gefalteten Kupfertafeln. Moderner Halblederband im Stil der Zeit.
Sehr seltene erste Ausgabe dieser beiden bedeutenden Arbeiten aus den Philosophical Transactions. - "The two papers entitled 'Experimental Enquiry into the Natural Powers of Wind and Water to turn Mills' were first presented to the Royal Society on 3 and 24 May 1759; for them Smeaton was awarded the Society's Copley medal. The first outstanding engineer to use cast iron to any extent, Smeaton made use of it in the construction of windmills, water wheels and pumps. The work is devoted to experiments on undershot water wheels, overshot wheels and on the construction and effects of windmills sails. The results of these experiments demonstrated the greater efficiency of overshot water wheels" (R&T). - Papierbedingt gering gebräunt und stellenweise leicht stockfleckig. Einband leicht berieben, sonst wohlerhalten. - DSB 12, 461; Roberts & Trent S. 297
