Apparatus for Magnetic Precision Measurements The Fahy Permeameter Compensated Type Developed to meet the need for a reliable and convenient apparatus for the magnetic testing of single specimens (bars, rods, sheet material) and for the simultaneous comparison of two similar or dissimilar specimens. Fully described in Scientific Paper No. 306 of the U. S. Bureau of Standards. The Fahy Permeameter Simplex Type Represents a further distinct advance in the art of magnetic measurements. Specially designed to test single specimens only-two or more specimens can be compared, of course, by the results of consecutive tests-it fully retains the high accuracy and perfect consistency of the compensated apparatus, but gains considerably in simplicity of operation and speed of tests. The Magnet-Meter An instrument developed for the precise and rapid investigation of shaped permanent magnets, such as used in magnetos, electrical measuring instruments, etc. This instrument serves to determine not only the initial strength, but also the stability of magnets.

VAN NOSTRAND COMPANY PUBLISHERS AND 25 Park Place BOOKSELLERS NEW YORK MONOGRAPHS ON AND GENERAL PHYSIOLOGY The publishers take much pleasure in announcing a new series of monographs covering the subjects of experimental biology and general physiology. These volumes will be under the general editorship of Jacques Loeb, T. H. Morgan, and W. J. V. Osterhout. The aim and character of the series are indicated by the following announcement of the editors JACQUES LOEB, T. H. MORGAN AND W. J. V. OSTERHOUT The rapidly increasing specialization makes it impossible for one author to cover satisfactorily the whole field of modern biology. This situation, which exists in all sciences, has induced English authors to issue series of monographs in biochemistry, physiology, and physics. A number of American biologists have decided to provide the same opportunity for the study of experimental biology. Biology, which not long ago was purely descriptive and speculative, has begun to adopt the methods of the exact sciences, recognizing that for permanent progress not only experiments are required but that the experiments should be of a quantitative character. It will be the task of this series of monographs to emphasize and further as much as possible this development of biology. Experimental biology and general physiology are one and the same science, by method as well as by contents, since both aim at explaining life from the physicochemical constitution of living matter. The series of monographs on experimental biology will, therefore, include the field of traditional general physiology. The following is a list of the volumes published or in preparation. Published: Vol. 1. Jacques Loeb (Rockefeller Institute), "FORCED MOVEMENTS, TROPISMS, AND In Preparation: Price, $2.50 net. T. H. Morgan (Columbia University), "THE CHROMOSOME THEORY OF HEREDITY." H. S. Jennings (Johns Hopkins University), “PURE LINE INHERITANCE." R. Pearl (Johns Hopkins University), THE EXPERIMENTAL MODIFICATION OF THE PROCESS E. G. Conklin (Princeton University), “LOCALIZATION OF MORPHOGENETIC SUBSTANCES R. G. Harrison (Yale University), "TISSUE CULTURE.” W. J. V. Osterhout (Harvard University), "PERMEABILITY AND ELECTRICAL CONDUCTIVITY L. J. Henderson (Harvard University), "THE EQUILIBRIUM BETWEEN ACIDS AND BASES T. B. Robertson (University of Toronto), "CHEMICAL BASIS OF GROWTH.” G. H. Parker (Harvard University), "PRIMITIVE NERVOUS SYSTEM." A. R. Moore (Rutgers College), "COORDINATION IN LOCOMOTION." Other volumes are to follow. In making this announcement the publishers are looking for the whole-hearted cooperation of the scientific men of the country. They solicit correspondence and will be glad to book orders for delivery upon publication of the series or individual volumes. J. B.
