Aromatic fluorine compounds. II. 1,2,4,5-Tetrafluorobenzene and related compounds
G. C. Finger, F.H. Reed, D.M. Burness, D.M. Fort, R.R. Blough
1951, Journal of the American Chemical Society (73) 145-149
The synthesis and properties of 1,2,4,5-tetrafluorobenzene and a group of bromofluoro and chlorofluorobenzenes with a predominating 1,2,4,5-structure are described. Flash point and surface tension data for the fluorinated benzenes and the influence of chlorine substitution upon these values were studied. Under nitration conditions, 1,2,4,5-tetrafluorobenzene will not form a nitro derivative,...

Conservation: Where we stand: Review of Water, land, and people
Luna Bergere Leopold
1951, The Living Wilderness (36)
A distinguished conservationist, just returned from more than a year in those Pacific islands held in trust by the United States, reports that representatives of the government there are nearly completely concerned with the maintenance of an administrative organization. Actual advances in matters of land use, of maintaining the material...

Vegetation of Southwestern watersheds in the nineteenth century
Luna Bergere Leopold
1951, Geographical Review (41) 295-316
The recollections of many old-timers who tell of grass “stirrup high” have given rise to the idea that vegetation in the Southwest was uniformly better in the middle of the last century than it is at present. The change is usually attributed to overgrazing, which timed if it did not...

Rainfall frequency: An aspect of climatic variation
Luna Bergere Leopold
1951, Eos, Transactions, American Geophysical Union (32) 347-357
Analyses which have been made in the past have shown no significant trend in annual values of rainfall during the period of rainfall records in the southwestern United States. In the present study, frequency of daily rains of various sizes are analyzed for four long-record stations in New Mexico. It...

Ground-water situation in Oregon
R. C. Newcomb
1951, Report
The water that occurs beneath the land surface follows definite and well-known rules of hydraulics, the same as water on the surface. However, ground water must be studied by methods, some of which are unique to that type of water occurrence, in order to evaluate the part it plays in...

Determination of fluorine in organic compounds: Microcombustion method
H. S. Clark
1951, Analytical Chemistry (23) 659-661
A reliable and widely applicable means of determining fluorine in organic compounds has long been needed. Increased interest in this field of research in recent years has intensified the need. Fluorine in organic combinations may be determined by combustion at 900° C. in a quartz tube with a platinum catalyst,...

Downstream movement of recently transformed sea lampreys, Petromyzon marinus, in Carp Lake River, Michigan
Vernon C. Applegate, Clifford L. Brynildson
1951, Transactions of the American Fisheries Society (81) 275-290
In order to obtain more precise information concerning the downstream movement of recently transformed sea lampreys, a trapping device was operated in the Carp Lake River, Emmet County, Michigan, from October, 1948, to July, 1951. The period of downstream migration typically extends from the latter part of October to...
Fluorometric determination of zirconium in minerals
W.C. Alford, L. Shapiro, C. E. White
1951, Analytical Chemistry (23) 1149-1152
The increasing use of zirconium in alloys and in the ceramics industry has created renewed interest in methods for its determination. It is a common constituent of many minerals, but is usually present in very small amounts. Published methods tend to be tedious, time-consuming, and uncertain as to accuracy. A...

Geochemical field method for determination of nickel in plants
L.E. Reichen
1951, Analytical Chemistry (23) 727-729
The use of biogeochemical data in prospecting for nickel emphasizes the need for a simple, moderately accurate field method for the determination of nickel in plants. In order to follow leads provided by plants of unusual nickel content without loss of time, the plants should be analyzed and the results...
Aromatic fluorine compounds. IV. 1,2,3,5-Tetrafluorobenzene
G. C. Finger, F.H. Reed, R.E. Oesterling
1951, Journal of the American Chemical Society (73) 152-153
The preparation of 1,2,3,5-tetrafluorobenzene and some of its intermediates is described. Cuprous oxide as a catalyst was used to advantage in the hypophosphorous acid deamination method....
Determination of lithium in rocks: Fluorometric method
C. E. White, M. H. Fletcher, J. Parks
1951, Analytical Chemistry (23) 478-481
The gravimetric method in general use for the determination of lithium is tedious, and the final weighed product often contains other alkali metals. A fluorometric method was developed to shorten the time required for the analysis and to assure that the final determination is for lithium alone. This procedure is...
Determination of molybenum in soils and rocks: A geochemical semimicro field method
F. N. Ward
1951, Analytical Chemistry (23) 788-790
Reconnaissance work in geochemical prospecting requires a simple, rapid, and moderately accurate method for the determination of small amounts of molybdenum in soils and rocks. The useful range of the suggested procedure is from 1 to 32 p.p.m. of molybdenum, but the upper limit can be extended. Duplicate determinations on...
