Diminuti've in size bu ,with facilities of many stan da rd instruments
WORKERS in all branches of science find that the Bausch & Lomb Pocket Microscope exactly fulfills their requirements
for portable equipment. It can be slipped in the pocket or added to field kits-but it is equally as useful in the laboratory. Among its advantages may be mentioned-
Magnification-From 60 to 250 diameters. Illuminati'on-For both transparent and opaque specimens. Focusilng Adjustments-Coarse adjustment by sliding draw tube,
fine by focusing sleeve.
Size-Furnished in carrying case measuring 2Y4 x 2 Y4 x 5 inches. Weight, complete in case, 17 ounces.
M NA1Y scientists have tried to read human faculties backward inito the lower animals. Dr. Herrick reverses the order and, beginning with the simplest structures prophetic of cerebral cortex, he reads this history through to its
culmination in man. He centers his discussion about the blrains of rats and men, the two species of mammals whose behavior patterns have been studied most in- tensively under conditions of laboratory control. He demonstrates incisively that the entire intellectual, emotional, and moral life of mankind can be explored as biological functions without loss of their supreme values as distinctively human attributes, and without passing outside the realm of natural laws. This book touches problems that are fundamental to all the sciences that take living things, and man in particular, as their province: biology, psychology, anthro- pology, the social sciences, education, and medicine.

THE NATURE OF THE WORLD AND OF MAN
By Sixteen Members of the Faculties of the University of Chicago
S pretentious a program as this book presents has seldom beeni attempted: it J is an outline of our knowledge of the physical and the biological world, and
man's relative position in it. It is designed to give a preliminiary view of many rich intellectual fields, all marshalled together, in brief, to assist the indi- vidual in the important problem of forming a well-define[d conception of the cosmos and his relation to it. Beginning with the story of life from the origin of the earth to the point when man is defined as man, each of the sixteen authors has described that phase of development with which he is most familiar. And all have emphasized the con- ceptiort of science as a glowing, living thing inextricably bound up with every human life. These men, specialists in their fields, are the authors: Forest Ray Moulton, Rollin T. Chamberlin, J. iarlen Bretz, Harvey B. Lemon, Julius Stieglitz, Horatio Hackett Newman (the editor), Edwin Oakes Jordan, Merle C. Coulter, Henry Chandler Cowles, Warder C. Allee, Alfred S. Rorner, Fay-Cooper Cole, Elliot R. Downing, GOeorge W. Bartelmez, Anton J. Carlson, cand Charles Hubbard Judd.

AMERICAN MEN OF SCIENCE A BIOGRAPHICAL DIRECTORY
The third edition of the Biographical Directory of AMERICAN MEN OF $CI- ENCE was published in June, 1921, and contains the records of more than 9,500 living men of science, as compared with about 4,000 in the first edition and about 5,500 in the second edition. No single book of reference can cover the whole of North America and all lines of activity; it therefore becanie necessary to prepare special works. This volume, devoted to the men of science, sets standards in its treatment of a group on which the material prosperity and intellectual leadership of the country depend. This directory should be in the hands of all those who are directly or indirectly interested ini scientific work. Price: Ten Dollars, net, postage paid.

By BENJAMIN T. BROOKS A pioneer work thoroughly covering a branch of organic chemistry which has been
strangely neglected in the literature, although it has assumed a position of importance, in both applied and theoretical chemistry, quite equal to that of the benzene hydro- carbons.
To petroleum technologists and chemists whose work comes in contact with essen- tial oils, the terpenes, acetylene and its derivatives, etc., this book is of peculiar impor- tance. But its appeal is far wider than this-it should be read by every chemist eager to keep posted on the general advancement of the science.

The Science Press Printing Company has been established and equipped for printing scientific literature in the best way, with compositors, pressmen and proof-readers trained for technical work. It is a business corporation; but it has been founded to provide facilities essen- tial for the advancement of science. J. McKeen Cattell is president; A. E. Urban is general manager.
The corporation owns its building at Lancaster, Pennsylvania, over 14,000 square feet of floor space lighted on all sides, with space for printing a hundred scientific journals. It has the best ob- tainable presses, composing machinery and binding equipment and these will be increased as needed. What is more im- portant, it has the most competent press- men and compositors in a city which since "Science" was first printed there in I894 has become a center for fine scientific printing. The costs are only about three fourths as much as in the large cities.
The press prints "The Scientific Monthly," " Science," " School and So- ciety," " The American Naturalist" and a number of other scientific journals and publications. The typography and press- work of these journals will bear com- parison with any weekly or monthly pub- lication in the United States or else- where. Those authors who have read proofs will know the correctness of the composition. A distinguished scientific man wrote recently to the editor of " Sci- ence ": " I corrected my first proof a year before you were born and the one I re- turned yesterday was the first one in my long experience that needed no correc- tion."
All correspondence should be ad- dressed to the general manager, A. E. Urban, The Science Press Printing Com- pany, Lancaster, Pa.

The subjects of the experiments here presented were selected inmates of the California State Prison at San Quen- tin. Expert medical and dental examina- tion of tlhe subjects was always available and the ever present element of " Cus- todial Control" was a factor in causing the men to abide by the restrictions for the entire experimental period.

40,000 worcls. It gives the pronunciation, and conc,ise but clear definitions. Eponymic terms, of which a very large number are used in modern medical literature, are placed in alphabetical order throughout the book. Likewise, the various referenice tables are inserted in their alphabetical sections, where they will be quickly found. Among the numerous tables are those on muscles, nerves, arteries, microorganisms, thermometric scale comparisons, dose-lists, veterinary dose-lists, weights and measures. The dose-list has been revised to accord with the U. S. Pharmacopoeia X which became official in January, 1926.

The Nervous Mechanism of Plants By SIR JAGIDIS CHUNDER BOSE, M.A., D.SC., LL.D., F.R.S., C.S.I., C.I.E. Director, Bose Research Institute, Calcutta. This work establishes the fact of the existence of a nervous system in plants. It begins with the problems of the conduction of excitation in the Sensitive Plant (Minosas Pudica) and shows that it is not a physical process affected through the liquid in the vessels of the plant, as either a hydro-mechanical disturbance or a movement of the sap, but is a physiological process of the protoplasm. This conclusion is based on the ex- perimental evidence that stimulation can be effected by means of involving no mechan- ,ical disturbance or wounding of the tissues, and that the velocity of conduction is much lighter than that of any movement of liquid in the plant.
