An assemblage of predominantly planktonic Foraminifera is discussed from rocks of Cenomanian age dredged from between 3,200 and 3,500 fm on the north slope of the Puerto Rico Trench. Thirty-three planktonic and benthonic species are described. Planomalina pulchella is new; nine species are specifically...
Spectrophotometric determination of fluorine in silicate rocks
L. C. Peck, V. C. Smith
1964, Talanta (11) 1343-1347
The rock powder is sintered with a sodium carbonate flux containing zinc oxide and magnesium carbonate, the sinter-cake leached with water and the resulting solution filtered. Fluorine is separated from the acidified filtrate by steam distillation and determined spectrophotometrically by means of a zirconium-SPADNS reagent. If...

Lloyd L. Smith Jr., Robert H. Kramer
1964, Transactions of the American Fisheries Society (93) 35-45
On the basis of 14,564 spottail shiners (Notropis hudsonius) from Red Lakes, Minnesota, growth rates, strength of year classes, and food utilization were studied. Males and females had different body-scale relationships, and females grew faster than males. There was high correlation between water temperature and growth rate. Strength of year...

A horizontal sampler for collection of water samples near the bottom
Leonard S. Joeris
1964, Limnology and Oceanography (9) 595-598
The need to obtain adequate water samples immediately above a lake bottom or at a precisely defined depth is not new. The problem is of particular concern in a large section of central Lake Erie, where dissolved oxygen concentration may be reduced to 1 ppm...
Numbered nasal discs for waterfowl
James C. Bartonek, C.W. Dane
1964, Journal of Wildlife Management (28) 688-692
Numbered nasal discs were successfully used in studies requiring large numbers of individually marked waterfowl. The procedure for constructing these discs is outlined. Blue-winged teal (Anas discors) with 5/8-inch discs, and canvasback (Aythya valisineria) and redhead (A. americana) with 3/4-inch discs can be individually identified up to 50 and 80...

Geology and ground-water conditions of Clark County, Washington, with a description of a major alluvial aquifer along the Columbia River
Maurice John Mundorff
1964, Water Supply Paper 1600
This report presents the results of an investigation of the ground-water resources of the populated parts of Clark County. Yields adequate for irrigation can be obtained from wells inmost farmed areas in Clark County, Wash. The total available supply is sufficient for all foreseeable irrigation developments. In a few local...
Crystal chemistry and structure refinement of five hydrated calcium borates
J. R. Clark, D.E. Appleman, C. L. Christ
1964, Journal of Inorganic and Nuclear Chemistry (26) 73-95
The crystal structures of the five known members of the series Ca2B6O11·xH2O (x = 1, 5, 5, 7, 9, and 13) have been refined by full-matrix least-squares techniques, yielding bond distances and angles with standard errors of less than 0·01 Å and 0·5°,...
Fused rock from Köfels, Tyrol
Daniel J. Milton
1964, Tschermaks Mineralogische und Petrographische Mitteilungen (9) 86-94
The vesicular glass from Köfels, Tyrol, contains grains of quartz that have been partially melted but not dissolved in the matrix glass. This phenomenon has been observed in similar glasses formed by friction along a thrust fault and by meteorite impact, but not in volcanic glasses. The explosion of a...
Records of wells and springs, water levels, and chemical quality of ground water in the East Portland area, Oregon
B. L. Foxworthy, G.M. Hogenson, E. R. Hampton
1964, Report
Data are presented on more than 300 wells, including many new ones whose records will not be a part of a forthcoming interpretative report on the occurrence of ground water in this area. A brief description of the geomorphic features is given, and the...
Origin of precambrian iron formations
H. Lepp, S. S. Goldich
1964, Economic Geology (59) 1025-1060
A statistical study of the chemical composition of the Precambrian iron formations of the Canadian Shield affords a new approach to the origin of these unusual formations. The average total iron content of 2,200 samples from the literature and from unpublished mining company analyses is 26.7 percent Fe. The average Fe content for 16 iron formations in the United States and Canada...

Effects on the shallow artesian aquifer of withdrawing water from the deep artesian aquifer near Sugarville, Millard County, Utah
R. W. Mower
1963, Utah State Engineer Water Circular 10
Ground water occurs in a shallow (unconfined) aquifer and in at least two artesian (confined) aquifers in the unconsolidated alluvial material composing the valley fill near Sugarville, Utah. No wells are known to withdraw water from the unconfined aquifer, and this report is limited to a discussion of the effects...

The Hexamita(= Octomitus) problem: A preliminary report
J. R. Uzmann, J.W. Jesse
1963, Progressive Fish-Culturist (25) 141-143
THE INTESTINAL FLAGELLATE, Hexamita salmonis (Moore), was described in 1922 from trout in hatcheries throughout New York State. At first associated with the so-called whirling disease of brook trout (Salvelinus fontinalis), now believed to be a virus disease, Hexamita was subsequently held responsible for practically any otherwise unexplainable mortality in...
