Price, S2, with discount of 20 per cent f o r orders of 10 or more. T H I S book embodies in brief form n o t only t h e usual methods of gas analysis, b u t also m e t h o d s of qualitative analysis a n d data o n t h e properties of gases, including their physiological action. I t is intended for those who, as s t a t e d in t h e Preface, have e n o u g h chemical sense or ''gumpt ion" t o set ii]) t h e different pieces of a p p a r a t u s without m i n u t e directions. However, very little knowledge of chemistry is assumed, t h e v o l u m e changes in t h e explosion of methane a n d hydrogen, for example, being shown b y e l e m e n t a r y diag r a m s . A chapter is devoted t o t h e care of cylinders of compressed gases a n d t h e precautions to b e used in handling these cylinders. The distinction between sewer gas a s combustible gas which h a s leaked into sewers, a n d sewage gas as one resulting from t h e decomposition of sewage is new t o the writer b u t seems justified. Professor Gill has compressed into this little volume m a n y observations resulting from his long experience. T h e book is p u t o u t in photolithographed form, which gives i t somewhat t h e appearance of being a preliminary edition. I t is. however, clearly printed a n d is easy t o read. Only minor misprints have been n o t e d . A. H .

While designed t o fall between a h a n d b o o k a n d a textbook for chemical engineers, it contains much valuable information for all engineers, some of whose specialties t a k e t h e m r a t h e r far afield from chemistry. Dr. Berl has a s s e m b l e d a n u m b e r of distinguished men t o c o n t r i b u t e t o w r hat m u s t b e for a long t i m e t o come a s t a n d a r d reference i n chemical engineering: R.

assistance of the publisher, have produced a v e r y readable treatise on engineering as it applies t o t h e chemical industries in particular. E a c h chapter is r a t h e r short, well arranged, a n d profusely illustrated (there a r e 2264 pages a n d 1802 illustrations in t h e whole work, or nearly one illustration per page), so that despite t h e m o n u m e n t a l character of t h e work a s a whole, reference to a n y particular subject is not time-consuming. T h e writer h a s only one unfavorable criticism—namely, that each volume is separately indexed, which m a y require looking in three indexes before t h e desired subject is located. T h e work must be purchased as a whole, since t h e purchase of one volume, according t o t h e publisher's notice, obligates t h e purchaser t o t a k e t h e remaining volumes.

IN* t h e new edition t h e methods are a r ranged in t h e general order adopted by t h e American Society for T e s t i n g Materials, while in previous editions t h e tests were grouped under headings of t h e individual products. M e t h o d s n o t sufficiently established in detail are classified as * 'tentative tests." Twenty-five new m e t h o d s are included, which cover also the testing of greases n o t considered in t h e previous editions. W i t h t h e following exceptions most of the new methods a r e either in complete accord or differ only slightly from those of t h e American Society for Testing M a terials: aniline point of kerosene, gas oil a n d fuel oil; drop point of greases, p e troleum jelly, and asphaltic b i t u m e n ; m a t t e r insoluble in carbon disulfide in n a t u r a l asphalts a n d asphaltic b i t u m e n ; sediment insoluble in benzene; smoke point of kerosene; sulfur (corrosive) in gasoline; tetraethyllead in gasoline; kinematic viscosity in absolute units which is of particular interest because of the present tendency in t h e petroleum industry to replace present commercial instruments b y absolute viscometers; burning test for kerosene; cold test for motor fuels; g u m (existent a n d potential) in m o t o r fuels; analysis of tar-bitumen m i x t u r e s ; a n d viscosity by means of t h e redwood a p p a r a t u s (multiple cup b a t h ) . While t h e book is of particular importance t o those who are primarily interested in B r i t i s h testing methods, it should also be of value to those who need reliable tests n o t y e t developed by t h e American Society for Testing M a t e r i a l s . It is to be regretted, however, t h a t u p t o the present t i m e t h e difference in standardization of tests in this country a n d in England makes books published in o n e c o u n t r y n o t completely a d a p t a b l e to t h e needs of t h e other. T h e book is well edited a n d is supplied with a comprehensive index.
