support rods ( 0 ) are maintained a t a fixed distance apart by a cross-member rigidly connected near the top of the rods ( p ) . The cross member visible at (p) is in turn clamped t o mounting rods secured to the water bath. This arrangement of supports and connectors serves as a mounting device t o suspend the solution bottles in a constant-temperature water bath and as bearings for the operation of the rod supporting the bottles. The water ( q ) provides adequate lubrication for the rod ends ( j ) in the connector bearings. The effective length of the tilting arm ( h ) is 6.3 cm., and it is operated by a
vertical stroke OI 5.5 cm., see above; therefore, the angle of tilt through which the solution bottles move is about 50“. sufficient to provide good agitation. When agitation has continued sufficiently long to saturate the solvent with solute the rod ( d ) is lifted off the supporting arm ( c ) and may be secured by a suitably mounted hook in such a position that the solution bottles are in an upright position. The excess solute is allowed to settle or may be centrifuged to produce a clear supernatant liquid for analysis.
Book Notices Treatise on Analytical Chemistry. Part 1: Theory and Practice. Vol. I. Edited by I. M. KOLTHOPF and PHILIP J. ELVING.Interscience Publishers, Inc., 250 Fifth Ave., New York 1, N. Y., 1959. xxvi 809 pp. 16 x 23.5 cm. Price single $17.50, subscription, $15. This is the first volume of the first of three parts of a comprehensive and systematic treatise on all aspects of classical and modern analytical chemistry, covering the scientific and instrumental fundamentals of analytical methods by critical selection and interpretation of methods and procedures for inorganic and organic compounds. Methods for investigation and evaluation of the properties and composition of commercial products will be included. The first four chapters (Section A ) of volume 1 take up “Analytical chemistry: its objectives, functions, and limitations.” Section B, chapters 5-19, covers “Application of chemical principles.” Each chapter is a contribution by an authoritative worker in the field discussed. References are given at the end of each chapter. Volume 1 does not contain an index but a detailed table of contents is provided. The Treatise is not intended to replace the great number of existing and exhaustive monographs on specific subjects, but rather to serve as an introduction and guide to the efficient utilization of specialized monographs. Volume 1, part 1 is a good beginning.
