Bull., 14(6):214-216. Essential physical factors affecting the formation of water-in-oil emulsions ('chocolate mousse') in the laboratory are irradiation by visible light and
mechanical agitation. It is suggested that photochemical oxidation of oil components leads to the formation of surface-active, oil-soluble compounds; when these reach a sufficient concentration, water is retained within the oil during physical mixing. The plausibility of such a mechanism is investigated using additions of tetradecanal as an oil-soluble, surface-active agent and fl-carotene as an inhibitor of photooxidation. The use of additives to stop 'mousse' formation is suggested.

The use of Foraminifera as indicators of tidal effects in estuarine deposits. Mar. Geol., 51(3/4):239-250.
With increasing tidal influence, transport of foraminiferal tests increases both as bed-load and especially in suspension. Suspended tests are generally very small (<200 /~m) and include many open marine species; upon sedimentation, they lead to high-diversity assemblages in environments with low diversity of living assemblages. The abundance of these exotic tests shows a progressive increase with increased tidal strength. Thus, the presence of size
sorting with small mean size, the diversity range, and the proportion of exotic individuals can be used to recognize tidal effects in ancient estuarine deposits. Dept. of Mar. Geol., Tong-ji Univ., Shanghai, China.

Seismic wave generation, propagation and detection are treated using a minimum of mathematics. Some of the necessary math tools (which do not include tensors) are covered in the first chapter. Subsequent chapters deal with plane waves and boundaries in isotropic and anisotropic media, models of Earth materials, loss mechanisms and attenuation, boreholes (the seismic waves in them, coupling, technical considerations), and sources and receivers (the theory behind them and practical cases). Includes 6 pages of references and author and subject indexes. Dept. of Geophys., Colorado Sch. of Mines, Golden, Colo. 80401, USA. (bas)
