" A useful work of reference for the gas engineer and all interested in lighting or heating by
gas, while the analyses of the various descriptions of gas will be of value to the technical chemist.
All matter in any way connected with the manufacture and use of gas is dealt with. The book has
evidently been carefully compiled, and certainly constitutes a useful addition to gas literature." —
Builder.
" The volume contains a great quantity of specialised information, compiled, we believe, from
trustworthy sources, which should make it of considerable value to those for whom it is specifically
produced. " — En^inter.
