NEW BOOKS. The Smokeless Combustion of Coal in Boiler Plants. By D. T. RANDALL A N D H. W.WEEKS. Bulletin 373, U. S. Geol. Survey. 8vo. pp. 188. Washington, Government Printing Office. 1909. This most recent and excellent contribution t o the smokeless combustion of coal will be welcomed by chemists and engineers everywhere. Bulletin 334, previously issued by the Survey, furnished a preliminary report on the same subject. Following the introduction, the present volume describes representative boiler plants burning coal without smoke, including plants with mechanical stokers and handfired furnaces, Following this are Some Observations a t Geological Survey Fuel Testing Plants, Comparison of Methods of Supplying Air for Combustion, Influence of Volatile Matter in Fuel on the Smoke Problem, Central Heating Stations, General Conclusions on Smoke Abatement, and Bibliography. The Bulletin should be in the hands of all fuel chemists and engineers. In their new catalogue of bacteriological apparatus, the Bausch & Lomb Optical Co. have added another interesting publication to their list. Aside from being very complete, the catalogue is of interest since it describes a new electric incubator, made in various sizes, which presents a number of unique features. These incubators are run on the main current without any auxiliaries whatever, and, being selfcontained, they require no more space than does the ordinary laboratory incubator. The many advantages attending the use of electrically heated incubators are too apparent t o call for consideration here. Several forms of opsonic incubators, of hot air sterilizers, steam pressure sterilizers, and autoclave afford a wide range of choice, while the water baths and paraffin ovens listed answer all laboratory requirements. I n addition to these items such accessories as thermo-regulators, thermometers and burners are given careful attention. This catalogue may be had gratis by addressing the Company a t Rochester, N.
