Perspex moist chamber for micromanipulation, P. A. Dixon, Experimentia, 14, 37-38 (1958). A description is given of a Perspex moist chamber for micromanipulation. analysis, M. Ishibashi, T. Fujinago, and I. Akamatsu, Apparatus for polarographic Japan. Pat. 3450, June 7, 1957. The effect of 02 dissolved in the solution to be analyzed is removed by alternate charging and discharging of the solution.
Two-wave-length method ojmicrospectrophotometry. I. Microspectrophotometer and tests on model systems, M. L. Mendelsohn, J. Biophys. Biochem. Cytol., 4, 407-14 (1958). A microspectrophotometer and tests on droplets of Sudan Blue are described. A simple rapid method for loading paper chromatograms, W. Chesbro, J. Chem. Educ., 36, 83 (1959). Paper punch disks of filter paper (6 mm,) are saturated with sample, dried, affixed to the chromatogram, and developed. Polarographic determinations in microcells, F. V. Sturm, J. Polarog. Sot., No. 2, 28-35 (1958). A 0.05-ml. microcell is described as suitable for determinations on as little as 1 pg. of material. A nd* 1ysis of 5 ~1. in a capillary ccl1 is mentioned. Method jar Jilling capillary pipets with mercury Biggs, J. Sci. Inst., 36, 45-46 (1959). A unique described for accurate filling of capillary pipets entrained air.

Liquid manometer with electromagnetic balance indicator, J. F. Kemp, J. Sci. Inst., 36, 77-81, (1959). A differential liquid manometer of the null-reading type with which analytical weights are used is described. The accuracy claimed for the instrument is 0.0005 mm. at 0.1 mm. differential range.

Automatic scanner for electrophoresis and chromatography paper strips, G. Smiljanic and T. Rabuzin, J. Sci. Znstr., 36, 160-63, (1959). An automatic device for Recording of optical density, scanning as a function of position is described. integral of optical density, radioactive intensity and its integral is discussed. Quick acting chemical balance, B. 0. Smith and J. W. Stevens, J. Sci. Inst., 36, 206-209 (1959). A quick-acting chemical balance suitable for repetitive weighings to an accuracy of 1 part in 5000 is described. Proximity meter and capacitance bridge are used and conventional knife edges are eliminated. MICROCHEMICAL
