The company has been well managed along conservative lines, as indicated by dividends paid, which from 1863 to 1914, inclusive, were a t the rate of 12 per cent; from January 15, 1915,

a charter for ten years, t o engage in a chemical m a m facturing enterpricr, to which they gave the name Pennsylvania Salt Manufacturing Company. The capital stock consisted of twenty shams of $5000 each. The board consisted of 6ve directors, aiid iialiona, Pa., was chosen for thelocation of the p h n t . Before the expiration of the first charter, a renewal for twmty years had been secured, and in 1879 the charter was again renewed, this time for 999 years. The growth of business has necessitated niimexoiis increases in the capital stock, which now amounts to %7,5Oo,WO,in addition to the stock of subsidiary companies CrVAtCd to serve the parent company. These include the Natrona Water Compaiiy, two light and power companies, a railroad and a coal company, the stoms company a t Natrona, the hlichigan Electrochemical Company. and the most recent, the Tacoma Electrochemical Company with capital stock of a million dollars, incorporated it, November, 1927, and with a plant under construction a t Tacoma, Wash. The gcncial oilices of the company were in Pittsburgh from 1859 to 1843, when they removed to Philadelphia, in which city tliey hayc since heen located. Charles Lennig was the first president, and he has been Jollowcd hy ten others, the present incumbent bcing Miers Busch, elected to that ofice in 192G.

The one a t Natrona, Pa., established in 1850, is the largest of the group. In 1870 the plant a t Greenwich Point, in southern Philadelphia, was established; the one a t Wyandotte, Xlich., in 1898; while the Michigan Electrochemical Company, at Menominee. Mich., was purchased in 1924. As stated above, a plant a t Tacoma. Wash., is now under construction. The products of the company are chiefly those eoming under the heading of heavy chemicals, and include acids, caustic alkalies, alums, chlorine products, and acid phosphate. The following are worthy of special mention: The company is the pioneer matiufacturer of liquid clilorine in this country. A specially pure grade of caustic soda is manufactured for the artificial silk trade. A pure grade of salt (sodium chloride), free from CAkium

BOOK REVIEWS The Disposal of Sewage. BY T. H. P. VEAL. 173 pages. D. Van Nostrand Co., Inc., New York, 1928. Price, $4.25. This book gives a very interesting picture of sewage disposal as practiced in England. It was written primarily for students wishing t o acquire the main principles of sewage disposal without going into unnecessary detail. The book is divided into eleven chapters entitled: Introductory and Historical; Quantity of Sewage; Analyses of Sewage and Their Meaning; Preliminary Process; Settlement Processes; Bacteria Beds; Bio-aeration Tanks; Land Treatment; Disposal of Sludge; Lay-out and Cost of Sewage Disposal Works; and Sewage Disposal in Rural Districts. The author is a lecturer in civil engineering a t the University of Birmingham, which is located near one of England’s largest and most modern sewage-disposal plants. H e gives evidence of having first-hand information about this and other plants in England. Having visited a number of the British plants described in the book, the reviewer can appreciate the clearness and conciseness of the descriptions given. So far as British practice is concerned, the author seems t o have accomplished his purpose very well, and the book can be recommended to all who desire t o know something about sewage disposal as carried out a t present in England. From the American viewpoint the weakness of the book lies in its failure to indicate the high state of development attained in the activated-sludge process of sewage disposal, which is probably the most satisfactory and most efficient method known today. One large American plant is separating the sewage of a great city into practically pure water and an inoffensive dry powder of very high fertilizer value, the sale of which pays for about two-thirds of the total cost of operation of the plant. The value of the book for students might also have been increased by pointing out the logical lines of research for the future. However, any student of sewage disposal will find the book well worth having, if only for its fine presentation of British ARTHUR WILSON methods.-Jo“

references is almost entirely lacking, which leaves the hurried reader-and what reader is not hurried?-completely bewildered to find the pertinent reference. This in the reviewer’s opinion is the outstanding defect impairing the usefulness of a book which will become the constant companion of all those workers trying to achieve order out of the vagariousness of nitrogen and phosphorus.-J.

The Indian Materia Medica. BY K. M. NADKARNI.1460 pages. Published by the author, P. 0. Box 3558, Bombay 4, India. 1927. Price, Rs. 11-0-0 or Sh. 18 net. This work is difficult to evaluate properly, but as a compilation of information on medicinal materials commonly available in India i t is very interesting. A preface and introduction give briefly sources of information and some statements concerning Hindu principles of medicine, in which it is made clear that the book was written in an endeavor to renew interest in medical circles in India in the indigenous drugs of the country. The division on The Vegetable Kingdom refers t o 1053 drugs, the section on The Mineral Kingdom contains 54 items, and that on The Animal Kingdom, 51 items. There follow various appendixes-one c1ass:fying drugs according t o therapeutic and physiologic actions, another on certain specific medicinal uses of drugs, a third tabulating substitutes for imported foreign drugs, and others pertaining to approximate percentage composition of articles of food, vitamin content of same, and special reference to “principal forms of Ayurvedic preparations and methods of their preparation,” together with quite a full index. The statement of uses of drugs is not confined to scientificaliy demonstrated facts, but includes many uses that are evidently the result of custom and ancient practice in Hindu medicine. These data, however, constitute a source of inteiesting information of more historic than scientific value. In many cases apparently every use that has ever been suggested for a drug is mentioned without comment as t o whether or not the information A Comprehensive Treatise on Inorganic and Theoretical Chem- is correct.
