Crystal formation in furunculosis agar
G. L. Bullock, A. J. Ross
1964, Progressive Fish-Culturist (26) 25-26
SINCE ITS INTRODUCTION SOME MONTHS AGO, FURUNCULOSIS AGAR has been employed in the diagnosis of suspect furunculosis and also as a general purpose medium. During our work with this medium we have noticed discrete "colonies," of crystalline material, which very closely resemble microbial colonies. These crystal colonies are compact and appear...

Minor-element composition and organic carbon content of marine and nonmarine shales of Late Cretaceous age in the western interior of the United States
H. A. Tourtelot
1964, Geochimica et Cosmochimica Acta (28) 1579-1604
The composition of nonmarine shales of Cretaceous age that contain less than 1 per cent organic carbon is assumed to represent the inherited minor-element composition of clayey sediments delivered to the Cretaceous sea that occupied the western interior region of North America. Differences in minor-element content between these samples and...
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°,...
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...
Catalytic determination of vanadium in water
M. J. Fishman, M. W. Skougstad
1964, Analytical Chemistry (36) 1643-1646
A kinetic determination of V(V) as a catalyst was spectrophotometrically performed by using the indicator reaction of Gallamine blue (GB+) and bromate at pH 2.0. The reaction was followed by measuring absorbance change for a fixed-time of 3 min at 537 nm. The variables such as reagent...
The electrum-tarnish method for the determination of the fugacity of sulfur in laboratory sulfide systems
P. B. Barton Jr., P. Toulmin III
1964, Geochimica et Cosmochimica Acta (28) 619-640
A new method for the determination of the fugacity of sulfur in laboratory systems consists of visual observation of the development and decomposition of a sulfide tarnish phase on silver-gold alloy (electrum) of precisely known composition. The alloy system is calibrated against pure sulfur. The method has the following advantages:...
A thermodynamic study of pyrite and pyrrhotite
P. Toulmin III, P. B. Barton Jr.
1964, Geochimica et Cosmochimica Acta (28) 641-671
Through the use of the electrum-tarnish method the following equation has been found to interrelate the composition of pyrrhotite, fugacity of sulfur, and temperature: In this equation fs2 is the fugacity of sulfur relative to the ideal diatomic gas at 1 atm, N is the mol fraction of FeS in pyrrhotite (in the...
Cenomanian (Cretaceons) Foraminifera from the Puerto Rico Trench
R. Todd, D. Low
1964, Deep-Sea Research and Oceanographic Abstracts (11) 391-393
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...

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...
Infrared surveys of Hawaiian volcanoes
W. A. Fischer, R.M. Moxham, F. Polcyn, G.H. Landis
1964, Science (146) 733-742
Aerial infrared-sensor surveys of Kilauea volcano have depicted the areal extent and the relative intensity of abnormal thermal features in the caldera area of the volcano and along its associated rift zones. Many of these anomalies show correlation with visible steaming and reflect convective transfer of heat to the...
Pentaborate polyanion in the crystal structure of ulexite, NaCaB5O6(OH)6*5H2O
Joan R. Clark, Daniel E. Appleman
1964, Science (145) 1295-1296
Triclinic ulexite crystals contain isolated borate polyanions [B5O6(OH)6]3- related to the well known pentaborate polyanion [B5O6(OH)4]- by addition of two hydroxyl groups to two opposite B-O triangles. The isolated ulexite polyanions form the [B5O7(OH)4]n3n- chains previously found in crystals of the related mineral probertite, NaCaB5O7(OH)4·3H2O....
Submicroscopic spherules and color of tektites
A. N. Thorpe, F. E. Senftle
1964, Geochimica et Cosmochimica Acta (28)
Magnetic susceptibility measurements of 18 tektites from various strewn fields have been made as a function of temperature from 77°K to room temperature. A relatively large temperature-independent component of the magnetic susceptibility was observed in all cases, and an analysis of the data...

Movements, growth, and rate of recapture of whitefish tagged in the Apostle Islands area of Lake Superior
William R. Dryer
1964, Fishery Bulletin (63) 611-618
A total of 1,303 whitefish were marked with spaghetti streamer tags in Wisconsin waters off Lake Superior in November of 1959, 1960, and 1961 and June-July 1960. The fish tagged in June-July 1960 were mostly undersized (less than 17 inches long) whereas those captured on the spawning grounds and tagged...
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...
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...
Age, growth, sex ratio, and maturity of the whitefish in central Green Bay and adjacent waters of Lake Michigan
Donald Mraz
1964, Fishery Bulletin of the U.S. Fish and Wildlife Service (63) 619-634
This study is based on 1,023 whitefish, Coregonus clupeaformis (Mitchill)--819 in seven samples from five localitites in central Green Bay in 1948-49 and 1851-52 and 204 in a single 1948 collection from northwestern Lake Michigan proper. Records of age indicated unusual strength for only one year class--1943 which strongly dominated...
The spottail shiner in Lower Red Lake, Minnesota
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...
Life history of lake herring in Lake Superior
William R. Dryer, Joseph Beil
1964, Fishery Bulletin (63) 493-530
The average annual commercial catch of lake herring (Coregonus artedi) in U.S. waters of Lake Superior was nearly 12 million pounds in 1929-61. This production contributed 62.4 percent of the total U.S. take of lake herring for the Great Lakes. About 90 percent of the annual catch is...
