BIBLIOGRAPHY for GENERAL CHEM- ISTRY from SEVERAL PERIODICALS*

I.? CHEMICAL AND METALLURGICAL ENGINEERING$

Volume 1 (1902) through 41 (1934)

Princeton Universitv, Princeton, New Jersey

I T IS amazing that so many articles in our technical journals may be intelligently read by students who have had practically no chemistry; but such is the

case for those articles in the following bibliography which has been developed a t Princeton for reference work in original literature. This encourages indi- vidualism, offers contact with methods of research, and, because of the latitude of subjects from which the stu- dent is free to choose, has been one of our most stimu- lating projects.

The responsibility of abstracting one of these articles replaces a certain amount of pedantic drudgery in re- writing experiments performed in the laboratory; and it amplifies the "independent reading" prescribed for those taking a course in chemistry without laboratory work.

The bibliography has not been compiled by referring to the indices, but by a careful paging of each volume. Processes which are obsolete, such as the arc process for nitrogen fixation, have been omitted. The following items are recorded for each article. Number (best ar- ticles stasred), title, author, periodical, volume, inclusive pages, and year. Sub-titles; a detailed abstract of the contents of the article. Pictures (photographs), fig- ures (diagrams of apparatus), graphs, etc.; f roa which the type of article may often be inferred. The author's estimate of the article. This is catalogd, for uniformity, under the headings:

POPULAR Historical Raw matcriais praceues Prodvets Propertien Economies No organic required Little chemistry

CHEMICAL ENGlNEERlNG Equations Research Advanced Mathematics organic required Biologied

Only the general approach classifies the article; thus mere reference to one or two previous workers in the

field would not qualify it as "historical." The absence of any one of these headings indicates that such mate- rial is lacking. Reading time, estimated from the amount of printed matter; no attempt being made to approximate the time it would take a student to ab- stract the article. Very short articles have been omitted, since this bibliography proposes, in so far as is reasonable, to supply the student with references in- volving approximately two hours' work. In the case of brief articles two may be assigned.
