His >eventh review of the literature T of analytical chemistry relating to nonferrous metallurgy is based on material received during the 2-year period ending AuguPt 1958. References to foreign publications are drawn largely from abstracting journals, and the present revieli may be as much as a year in arrears in such cases. Several references to work with nuclear materials are included n hich, although no longer new, have only recently been declassified. Because of the continuing growth in the number of publications in the field, the tabular form of presentation used in the preceding review (226') is retained. One change has been made t o increase the usefulness of these tables.A column has been added to indicate the approximate conctmtration range of each method, the division being made arbitrarily a t the 0.05% level. Methods designed primarily for amounts above 0.05% are marked G (gross), while those intended for concentrations less than that are designated by bI (minor).The methods included are reprevntative of current nork and recent developments of gmrral interest although no claim is made to exhaustive coverage. Thf preponderance of foreign publications, noted in the preceding review, holds for this present review period n ith approximately the following dihtribution: Vnited States, 36%;Russia and Eastern Europe, 227,; United Kingdom, 16%; Japan, 12%;Germnn! ~ 11 % ; remainder, chiefly France, Italy, and Spanish-speahing countrie,-, 37,.More than 450 referencts were scanned for trcwds in techniques. Cf about GOO separate methods of element determination published during this biennium, 3470 used spectroscopic methods (including direct readers) ; 28% n ere spectrophotometric; 12% polarographic; 127, titrimetric; 6% gravimetric; 47, radiometric; 27, flame spectrophotometric; 11 hile the reniaining 2y0 included nephelometric, fluorometric, x-ray absorption, etc.
