This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed.

The book before us is a revised and enlarged edition prepared by the late Mr. Bryan Donkin's secretary, and it has lost nothing in interest at this gentleman's hands. The work has been brought up to date, and the latest practice under each head is given; the increase in size and efficiency of gas engines recently built is particularly dealt with, and the descriptions of many foreignmade machines and of the principles governing their design are valuable as guides to home manufacturers.

Under the first head every type of gas producer, from the Dowson to the Mond. is described, and if the reader is only familiar with power produced by steam plant or gas engines served from public supplies, he is recommended to compare the results obtained from engines driven by producer gas with those from ordinary gas or steam. The suction gas producer referred to on p. 231 is more
