Comparison of English and Foreign Measures

This work is printed in a pearl type, and is so small, measuring only 2 1/2 in. by 1 3/4 in., by 1/4 in. thick, that it may be easily carried in the waistcoat pocket.

"It is certainly an extremely rare thing for a reviewer to be called upon to notice a volume measuring but 2 1/2 in. by 1 3/4 in., yet these dimensions faithfully represent the size of the handy little book before us. The volume - which contains 118 printed pages, besides a few blank pages for memoranda - is, in fact, a true pocket-book, adapted for being carried in the waistcoat pocket, and containing a far greater amount and variety of information than most people would imagine could be compressed into so small a space.....The little volume has been compiled with considerable care and judgment, and we can cordially recommend it to our readers as a useful little pocket companion."

Analysis, Technical Valuation, Purification and Use of Coal Gas, by the Rev. W. R. Bowditch, M.A., with wood engravings, 8vo, cloth 12 6

E. & F. N. SPON: LONDON AND NEW YORK.

Condensation of Gas - Purification of Gas - Light - Measuring - Place of Testing Gas - Test Candles - The Standard for Measuring Gas-Light - Test Burners - Testing Gas for Sulphur - Testing Gas for Ammonia - Condensation by Bromine - Gravimetric method of taking Specific Gravity of Gas - Carburet-ting or Naphthalizing Gas - Acetylene - Explosions of Gas - Gnawing of Gas-pipes by Rats - Pressure as related to Public Lighting, etc.

"While the Gas Question is claiming the attention of the inhabitants of London and many of the large provincial towns, Mr. Bowditch's book must prove useful. The whole subject of the production, purification, and use of Gas, is treated in a perfectly exact, yet at the same time in a clear and concise manner. The Gas manager will find in its pages a careful examination by a man of science and great experience of all the methods which have been introduced for removing the non-illuminating and offensive principles from Coal Gas. The use of the Photometer in all its varieties is described, etc., with an important chapter on testing Gas." - Athenaeum.
