The oxidizing power of illinois coal. I. The reaction with titanous chloride
G.R. Yoke, C. Alex Harman
1941, Journal of the American Chemical Society (63) 555-556
Illinois coals which have been exposed to air or oxygen show a small but definite ability to oxidize titanous chloride. This oxidizing power is gained very rapidly when freshly ground coal is exposed to air. Neither the magnitude nor the rapid increase of this oxidizing power can be accounted for...
Determination of small quantities of fluoride in water: A modified zirconium-alizarin method
W.L. Lamar, C.G. Seegmiller
1941, Industrial And Engineering Chemistry Analytical Edition (13) 901-902
The zirconium-alizarin method has been modified to facilitate the convenient and accurate determination of small amounts of fluoride in a large number of water samples. Sulfuric acid is used to acidify the samples to reduce the interference of sulfate. The pH is accurately controlled to give the most sensitive comparisons....
Bathymetric distribution of fish in lakes of the northeastern highlands, Wisconsin
Ralph Hile, Chancey Juday
1941, Transactions of the Wisconsin Academy of Sciences, Arts, and Letters (33) 147-187
The present study of the bathymetric distribution of fish in the lakes of northeastern Wisconsin has been based on records of the catches of gill nets fished during the summers of 1930, 1931 and 1932. During the first of the three summers, soundings were made only of the general area...
Age, growth, and production of the yellow perch, Perca flavescens (Mitchill), of Saginaw Bay
Ralph Hile, Frank W. Jobes
1941, Transactions of the American Fisheries Society (70) 102-122
Ages were determined and individual growth histories computed from the examination and measurement of scales from 820 yellow perch collected in 1929 and 1930. Calculated lengths greater than 101 millimeters were computed on the assumption (supported by empirical data) that the ratio of body length to scale length is constant....
Age and growth of the rock bass, Ambloplites rupestris (Rafinesque), in Nebish Lake, Wisconsin
Ralph Hile
1941, Transactions of the Wisconsin Academy of Sciences, Arts, and Letters (33) 189-337
The present study of the age and growth of the Nebish Lake rock bass is another in a series of papers that have been based wholly or in part on materials collected in the course of investigations on the fishes of the lakes of the northeastern highlands, Wisconsin, conducted cooperatively...
Geologic structure and occurrence of gas in part of southwestern New York
Wilmot H. Bradley, James F. Pepper, G. B. Richardson
1941, Bulletin 899
The area covered by this report is in southwestern New York and includes a little more than 3,000 square miles in Steuben and Yates counties and parts of the six adjacent counties. This area has been mapped to determine the structural attitude of the exposed rocks, so as to aid...
Experiments upon the control of Trichodiniasis of salmonid fishes by the prolonged recirculation of formalin solutions
Frederic F. Fish, Roger E. Burrows
1940, Transactions of the American Fisheries Society (69) 94-100
In a search for more effective disinfectants to combat parasitic diseases of hatchery fish, the authors report results from a series of experiments designed to determine the toxicity of varying exposures to concentrations of formalin, sodium p‐phenolsulphonate, ammonium sulphate, and sodium benzoate. Non‐toxic concentrations of these disinfectants were tested, in...
An evaluation of trout culture
1940, Transactions of the American Fisheries Society (69) 85-89
In an evaluation of the efficiency of trout culture, the author presents a detailed analysis of complete loss records from 288 individual lots of trout at twenty-two hatcheries in the western United States. Summarized data are given to show the percentage loss of eggs, fry, and fingerlings by progressive one-half...
Formalin treatments pass new tests. Additional notes on the control of ecto-parasitic protozoa
1940, Progressive Fish-Culturist (7) 31-32
After the completion of the eхреriments reported recently, in which the efficacy of formalin in controlling infections of Gostia mecatrix was demonstrated, the author was afforded an opportunity to test the value of formalin solutions in combatting established mixed infections of (Gyrodactylus, Tricbodina, Cyclochaeta) and a stalked protozoan on rainbow...
Calomel versus carbarsone
F. F. Fish, D.L. McKernan
1940, Progressive Fish-Culturist (7) 26-29
No parasite common to hatchery salmon and trout possesses quite so varied a reputation as does Octomitus salmonis. Discovered, studied, and described independently, but essentially simultaneously, by Dr. Emmeline Moore and Dr. H. S. Davis, Octomitus salmonis was introduced to fish culture during the early twenties. This easily found and widely...
Formalin for external protozoan parasites: A report on the prevention and control of Costia necatrix
Frederick S. Fisher
1940, Progressive Fish-Culturist (7) 1-10
The smallest and most destructive of the ectoparasitic protozoans infecting salmon and trout, Costia necatrix, has unfortunately been relegated to virtual obscurity during the past few years. Few references to this parasite can be found in the recent literature and, where such things are discussed, one seldom hears a mention of Costia...
