Ultraviolet spectrophotometric determination of tantalum with pyrogallol
J. I. Dinnin
1953, Analytical Chemistry (25) 1803-1807
In a search for a more rapid method for the determination of tantalum in rocks and minerals, an intensive study was made of the tantalum-pyrogallol reaction recommended by Platanov and Krivoshlikov, and a better modified spectrophotometric procedure is given. The improved method consists in measuring the absorbancy of the tantalum-pyrogallol...
The addition of iodine to tetramethylammonium iodide
H. W. Foote, M. Fleischer
1953, Journal of Physical Chemistry (57) 122-125
The system tetramethylammonium iodide-iodine-toluene has been studied by the solubility method at 6 and at 25°. The compounds (CH3)4NI3, (CH3)4NI5 and (CH3)4NI11 were found to be stable phases at both temperatures. In addition, the compound (CH3)4NI10 was found at 6° and the compound (CH3)4NI9 at 25°. The dissociation pressures of...
Semiquantitative spectrographic method for analysis of minerals, rocks, and ores
C. L. Waring, C. S. Annell
1953, Analytical Chemistry (25) 1174-1179
The quantity and complex nature of materials received for analysis in the spectrographic laboratories of the U. S. Geological Survey have emphasized the need for a spectrographic method to determine a maximum number of elements in a limited time with a reasonable degree of accuracy. The semiquantitative method described determines...
Geochemical studies of clay minerals III. The determination of free silica and free alumina in montmorillonites
Margaret D. Foster
1953, Geochimica et Cosmochimica Acta (3) 143-154
Determination of free silica by the method proposed made possible the derivation of logical formulas for several specimens of montmorillonites for which the formulas could not be derived from the analyses alone. Other montmorillonites, for which logical formulas could be derived from their analyses, were found to contain small amounts...
Determination of traces of cobalt in soils: A field method
H. Almond
1953, Analytical Chemistry (25) 166-167
The growing use of geochemical prospecting methods in the search for ore deposits has led to the development of a field method for the determination of cobalt in soils. The determination is based on the fact that cobalt reacts with 2-nitroso-1-naphthol to yield a pink compound that is soluble in...

Quercetin as colorimetric reagent for determination of zirconium
F. S. Grimaldi, C. E. White
1953, Analytical Chemistry (25) 1886-1890
Methods described in the literature for the determination of zirconium are generally designed for relatively large amounts of this element. A good procedure using colorimetric reagent for the determination of trace amounts is desirable. Quercetin has been found to yield a sensitive color reaction with zirconium suitable for the determination...
Systematic variation of rare earths in monazite
K. J. Murata, H. J. Rose Jr., M. K. Carron
1953, Geochimica et Cosmochimica Acta (4) 292-300
Ten monazites from widely scattered localities have been analyzed for La, Ce, Pr, Nd, Sm, Gd, Y and Th by means of a combined chemical and emission spectrographic method. The analytical results, calculated to atomic percent of total rare earths (thorium excluded), show a considerable variation in the proportions of...
Lake Bonneville: Geology of northern Utah Valley, Utah
C. B. Hunt, H.D. Varnes, H. E. Thomas
1953, Professional Paper 257-A
Lake Bonneville was a vast Pleistocene lake that covered 20,000 square miles in northwestern Utah and had a maximum depth of about 1,000 feet. It was a body of water comparable in size to modern Lake Michigan.Surveys of the unconsolidated deposits in the Lake Bonneville basin utilize the same methods...
Interpreting geologic maps for engineering purposes: Hollidaysburg quadrangle, Pennsylvania
Water Resources Division, U.S. Geological Survey
1953, Report
This set of maps has been prepared to show the kinds of information, useful to engineers, that can be derived from ordinary geologic maps. A few additional bits of information, drawn from other sources, are mentioned below. Some of the uses of such maps are well known; they are indispensable...
The effect of ether anesthesia on fin-clipping rate
Paul H. Eschmeyer
1953, Progressive Fish-Culturist (15) 80-82
As part of an experimental program to learn the effects of stocking lake trout (Salvelinus namaycush) in Lake Superior, 141, 392 fingerlings were marked at the Charlevoix (Michigan) Station of the U.S. Fish and Wildlife Service in October 1952. The adipose fin was removed from all fish, the right pelvic...
Perch studies in Green Bay
Ralph Hile
1953, Progressive Fish-Culturist (15) 133-134
For years the commercial fishermen of southern Green Bay contended that the minimum length of 8 inches for yellow perch in that are should be reduced because (1) the perch population was stunted, incapable of reaching the size of 8 inches in any numbers, and (2) the larger perch tended...

GILL DISEASE among fish, a disease which is characterized by a proliferation of the gill epithelium, has been attributed to a number of different causes. Generally, there are two recognized types: the eastern or bacterial type, in which long filamentous bacteria can always be demonstrated; and the western type, in...
