    Description: Calcium absorbtion was measured in fasting human beings after oral administration of Ca^45 in a solution containing 10 to 500mg stable calcium and an intravenous dose of Ca^47. Absorbtion was determined from the ratio of specific activities of the two isotopes (oral dose/intravenous dose) in calcium of urine collected more than 24 hours later. The accuracy of this calculation was confirmed by comparison with absorbtion calculated from recovery of the oral dose in stools (the completeness of collection being determined from recovery of simultaneously given Cr2O2or Cr^51 labeled protein and a correction for endogenous calcium being made from the fecal recovery of the intravenouse dose of Ca^47). In 20 tests, the average difference between the two calculations of per cent absorbtion was 2.2 and the coefficient of variation, 1.6. The Conditions under which the double isotope procedure gives an accurate result were evaluated and the results of its use with 3 different doses of calcium given to normal subjects are reported

    Description: This paper summarizes the hydrogeology of the thick carbonate-evaporite sequence that extends from land surface to the oil horizons at depths of about 11,500 feet below sea level in southern Florida. It sets forth the few known facts about the hydrology of the deep water-bearing rocks and discusses a hypothesis concerning the cyclic flow of salt water related to geothermal heating in the Floridan aquifer. Meinzer (1923, p. 30) defined an aquifer as a "formation, a group of formations, or part of a formation that is water bearing." The connotation of quantity was included by the statement: "Few if any formations are entirely devoid of gravity ground water, but those that do not contain enough to be of consequence as a source of supply are not rated as water bearing." The quality of the water does not enter the definition, for if it did, a change in quality (as by salt-water encroachment) would correspondingly convert aquifers to nonaquifers. This paper treats permeable water-bearing beds as aquifers even though the contained water might be a brine seven times as salty as sea water and, therefore, normally not considered a source of supply.

    Description: Sedimentary iron and heavy-metal deposits of undetermined size have been found in the middle of the Red Sea some 2000 meters below the surface of the sea (Fig. 1). This discovery has been made from the Research Vessel Atlantis II, which is still at sea engaged in a series of oceanographic investigations which ultimately will end in November 1965, after the ship has circumnavigated the globe. The discovery is significant because the environment and the processes controlling deposition of heavy metals are observable and appear to be still active.

    Description: The Murray fracture has been thought to extend ashore into the Transverse Ranges of California, but a geophysical study shows no evidence of structural continuity between these features. Instead, basement morphology typical of the Murray fracture zone ends where its known magnetic and bathymetric expression dies out. Similarly, east-west Transverse Range structures change direction so that they are parallel to the northwest trend of the coast rather than crossing the continental shelf and slope. The lack of continuity suggests an independent development of the Transverse Ranges since at least mid-Tertiary time along an older structural trend continuous with the Murray fracture zone. Possibly a fundamental lineament in the crust, an extension of the Murray, inactive since at least the mid-Tertiary, provided a convenient trend for development of the Transverse Ranges in response to deformation along the San Andreas fault system. The Murray fracture zone is thought by some authors to be a transform-fault. The transform-fault hypothesis alleviates some difficulties that arise in explaining the origin of the zone by transcurrent faulting but equivalent uncertainties seem to accompany the newer explanation.
