โฆ Synopsis
filter and coming from a black body at a definite temperature matches that from the mantle. Further investigation is planned to determine the feasibility of some such method for those sources whose colors do not lie on the scale of color of a black body at various temperatures.
Data for some of the most common illuminants are given in the table.

A procedure for selecting samples to use in multivariate calibration, inspired by a paper by Zemroch, is proposed. The method developed is designed for multicollinear data and is based on cluster analysis. It selects among available spectra the samples to submit to chemical analysis and calibration.
IN this note we wish to report preliminary results from the analysis of the infra-red spectrum of cyclobutadiene silver nitrate ~4Vg-J NO3 in relation to possible structures for the complex cation. Table 1 shows the spectrum obtained with Unicam SPl.00 and Perkin-Elmer Model 21 spectrophotometers u
