the most exacting requirements and offer defi-nite advantages to teacher and student alike.

FROBISHER'S Fundamentals of BACTERIOLOGYNew (3rd) Edition-It is difficult to find words that do; this text full justice. Itis really a distinguished teaching instrument which perceptibly lightens the taskof teaching because it arouses the full interest of the student and retains it throughthe descriptions of what bacteria are, how they act and how they affect the every-day civilization in which the student lives. The functional approach is in keep-ing with modern trends and the skillful choice and placing of 398 illustrationsfurther add to the value of the text.By MARTIN FROBISHER, JR., S.B., SA.D., F.A.A.A.S.. F.A.P.H.A., Associate Professor in Bacteriology,The Johns Hopkins University. 824 pages, 51/2" x 7%", with 398 illustrations. $4.00

Laboratory Manualfor General Bacteriology

New-Designed for use with any standard bacteriologytext, this new manual is nicely suited for one-quarteror one-semester courses. Important is the emphasisplaced on morphological and physiological aspects.

Thompson's Introductionto Microorganisms

Emphasizing what bacteria do, this text presents itsmaterial in five units. Public health implications are

brought out and items of interest in agricultural andindustrial bacteriology are incorporated.

Johan G. C. T. Kjeldahl, born August 16,1849, at Jaegmrspris, on the Danish island,-nZealand. Liketrensen. who was born onthe same island, he received his education at inohe Wod of Chemistrythe University of Copenhagen.Prom 1876 to 1900 Kjeldahl was the direc-

tor of the Chemical department-of the Carls-berg Laboratory.

H3is fame rests largely on his method ofdetermining nitrogen. The Kjeldahl methodfor the determination of nitrogen and thevarious modifications worked out by others

has been of incalculable value to the world.It is doubtful if any other analytical method

has had such profound efEets upon-bothpure and applied chemistry. His prmcipal'researches were in, the field of fermentation,

chiefly enzymatic aorin. --

HUMAN ASPECTS OF SCIENTIFIC RESEARCHBy DR. WILLIAM A. HAMORMELLON INSTITUTE, PITTSBURGH, PA.

CONSPICUOUS throughout the world of to-day is thegreat diversity of science, which has been accom-plished by the wide extension of the frontiers ofknowledge of man and nature by the application ofresearch. This research may be looked upon as thescientific quest for the possible. More precisely, itfinds, observes, defines and applies positive facts byexperimental methods and inductive logic. Researchhas characterized the life of the universities, whichare primarily responsible for its existence. Havingcomprehended the spirit and power of research fromthe universities, the industries have utilized itsmethods in their own affairs with most beneficialresults.

It seems that wherever research is alive it grows.The past thirty-five years have seen the number of

industrial research laboratories in this country in-crease from a few to more than 3,000. But, withoutthe evolution of scientific investigation in the uni-versities, these industrial laboratories might neverhave been established. In addition to the very ideaof research the universities have supplied the in-dustries with men and women possessing knowledgenot only of the underlying scientific facts and theoriesbut of the methods and techniques of investigation.From the universities also has come much of thebasic knowledge of science on which modern tech-nology has been erected and will build in the future.The practical uses of science may be regarded asthe dividends declared every once in a while by pureresearch and research education. When such re-search and education are hindered these dividends
