    The American Society of African Culture (1966)
    Cambridge : Cambridge University Press
    The @journal of modern African studies 4 (1966), S. 367-369

    Notes: It is supposed that most readers of The Journal of Modern African Studies know something of A.M.S.A.C., its origins, and the programmatic implementation of its purposes; if not, then certainly of its existence. Accordingly, only a summary recapitulation of the Society's history of origin will be made here.

    National Physical Laboratory Radiocarbon Measurements IV (1966)
    Cambridge University Press
    Details
    Publication Date: 1966-01-01
    Description: The following list comprises measurements made since those reported in NPL III and is complete to the end of November 1965.Ages are relative to A.D. 1950 and are calculated using a half-life of 5568 yr. The measurements, corrected for fractionation (quoted δC13 values are relative to the P.D.B. standard), are referred to 0.950 times the activity of the NBS oxalic acid as contemporary reference standard. The quoted uncertainty is one standard deviation derived from a proper combination of the parameter variances as described in detail in NPL III. These variances are those of the standard and background measurements over a rolling twenty week period, of the sample δC14 and δC13 measurements and of the de Vries effect (assumed to add an additional uncertainty equivalent to a standard deviation of 80 yr). Any uncertainty in the half-life has been excluded so that relative C14 ages may be correctly compared. Absolute age assessments, however, should be made using the accepted best value for the half-life and the appropriate uncertainty then included. If the net sample count rate is less than 4 times the standard error of the difference between the sample and background count rates, a lower limit to the age is reported corresponding to a net sample count rate of 4 times the standard error of this difference.

    A technique for the precise measurement of small fluid velocities (1966)
    Cambridge University Press
    Details
    Publication Date: 1966-11-01
    Description: A technique for the quantitative measurement of fluid velocities in the range 0–5 cm/sec is described. The technique uses a pH indicator, is applicable in aqueous solutions and permits visualization and measurement of three-dimensional flow fields. © 1966, Cambridge University Press.

    Blocks of Plutonic Aspect in a Basaltic Lava from Faial, Azores (1966)
    Cambridge University Press
    Details
    Publication Date: 1966-02-01
    Description: A number of coarse-grained blocks, consisting of forsteritic olivine, chrome-diopside, calcic plagioclase, and chromite in varying proportions, were found in an ankaramitic basalt on Faial. With one exception, the blocks show remarkably little alteration. There is no evidence of zoning in any of the minerals. Indications of strain are frequent. Dark scoriaceous material is often present along intercrystal boundaries and fractures. The textures and gradations in composition suggest that these blocks were formed by crystal accumulation.
