FREtrDEYrn~, I-I. D. and J. J. LEE, 1963. Glenodinium halli n. sp. and Gyrodinium instriatum n. sp. dinoflagellates from New York water. J. Protozool., 10 (2): 182-189. Two new dinoflagellates, isolated from Long Island Sound and maintained axenically, are described. Gyrodinium instriatum nov. sp. changes shape and size as cultures age. Glenodinium halli nov. sp. is a delicately-armoured form whose plate structure differs slightly from the present diagnosis of the genus, but not sufficiently like any other genus in morphology or life history for inclusion elsewhere. In G. halli the size of the motile form and predominance of motile or vegetative stages are nutrient dependent. Both dinoflagellates illustrate the need for morphological descriptions based upon continuous culture methods in defined media. Fum, M., Y. SAXTO, S. YAStrDA and K. KUWABARA, 1963.

Refined enzyme preparations obtained with aluminium hydroxide (C~,) for adsorption at pI-[ 5, 7 and 8"2 were respectively eluted at pH 7 and 8.2, at pH 5 and 8"2 and at pH 7 and 5 ; they were so-called as S r and Ss.2, N5 and Ns.2 and A~ and AT. The values of the activity were 49 and 52 for $7 and Ss.z, 32 and 37 for N5 and Ns.2, while 63 and 64 for A5 and AT. The values of the activity for N~ and Ns..~ were analogous to that of the refined enzyme preparation such as Bioprase manufactured from Bacills subtilis var.

Ass. Island Mar. Labs., 4th Meet., Curacao, 18-20. Nov. 1962: 11. The author analysed the hydrographic conditions in the Caribbean using the IGY data. From these it is estimated that sinking probably occurs in the central Caribbean. Mean water temperatures and mean salinities increase continuously towards the west, especially from 12~N to 16°N. With T-S curves, the water of the 300 m layer in the eastern section (64 ° 40'W) corresponds to water of the 400 m layer in the western section (79 ° 10'W). The oxygen is low in the eastern section (64 ° 40'W), but high in the western section (73 ° 50'W). This is similar to Parr's (1933) observations. Thus, the author concludes that convergence generally occurs in the centre of the Caribbean Sea.
GILBERT, PERRY W. and STEVEN D. DOUGt.AS, 1963. Electrocardiographic studies of freeswimming sharks. Science, 140 (3574): 1396. Electrocardiograms were taken of young lemon sharks, Negaprion brevirostris, as they swam freely in a circular concrete pool. Electrodes attached to the fin and torso yielded negligible or minute deflections, but direct leads yielded satisfactory recordings. GLANGEAUD, L., 1963. Evolution des magmas oc6aniques et continentaux d'apr6s les donn6es statistiques modernes. C.R., Acid. Sci. Paris, 256 (23): 4947-4950. L'auteur montre comment des corr61ations statistiques entre les rfsultats obtenus par diff6rentes m6thodes g601ogiques, g6ophysiques et g6ochimiques, permettent de poser correctement les prob16rues concernant l'6volution des magmas et les ' associations ' de roches 6ruptives.

Cir. Eng., 89 (WW2): 29-54. Results are presented of an investigation to test the hypothesis that the heights of ocean waves generated by a moving storm can be described by a Rayleigh distribution. Although chi-squared tests do not substantiate this hypothesis, the assumption of a Rayleigh distribution to describe wave heights yields results in several areas of practical importance that agree with measured data. The results reported herein are from studies of wave-height data measured in the Gulf of Mexico during two hurricanes and two tropical storms. The Rayleigh distribution appears to be justified for practical use by forecasters to calculate certain statistical parameters such as the ratio between the average of the highest 1/n waves (Hdn) or the highest wave in a group of N waves (Hmax) and the average wave height (.Havg) or the root mean square wave height (Hrms). This conclusion agrees with the results of other investigators who studied data gathered under different and, in general, less servere oceanographic conditions.
GORSLINE, D. S., 1963. Bottom sediments of the Atlantic shelf and slope off the southern United States. J. Geol., 71 (4): 422-440. The submarine geology of the South Atlantic continental shelf and slope of the United States has been described using data from bottom sediment samples collected aboard the Research Vessel T. N. Gill in 1953-54, combined with information from the geologic literature. Patterns of distribution of sediment types and characteristics show several broad trends. Shelf sediments are mixtures of quartz and shell fragments in various proportions with minor amounts of phosphorite (probably collophane) and a local concentration of glauconite.
