"The historical and technical evolution of the barometer during the three centuries since its invention is systematically and thoroughly documented... The author has furnished extremely valuable new data about many of the instrument makers... The more significant of the surviving barometric instruments are listed and described in a 20-page appendix, an extremely useful addition to a most impressive and valuable reference work for the historian of science and of technology alike. The book is clearly written and beautifully presented. It is thoroughly indexed and well illustrated throughout."
