By the employment of a micro-spectrophotometer it has been shown that Van Dyke's results, obtained by the indirect method of elliptical analysis, are substantiated. The region of the spectrum covered in this determination of the principal reflecting powers of tellurium extends from 4400 A°. u. to 6600 A°. u. The writer has described elsewhere the apparatus and method used.
