Analyses of Books . 
[May, 
in the Royal College of Science for Ireland, while Professor of 
Chemistry in that Institution ; the result being the treatise now 
before us, containing 136 pages, and about a dozen excellently 
executed woodcuts, drawn to scale, including Dr. Siemens's 
Regenerative Gas-Furnace. 
The chapters dealing with the Technical Examination and 
Analysis of Fuel, Pyrometers, and the Regenerative Gas-Furnace 
are those in which we were particularly interested. 
There are some points on which we might have expedted 
greater fulness, but as regards clearness of description nothing 
is to be desired. On the whole we congratulate Mr. Galloway 
on his undertaking, and can recommend the work as a very 
useful companion to the technological chemist, as well as to the 
manufacturer who is interested in the question of the economy 
of fuel.
