A potometer, working on a syphon principle, is described for use with single, small plants where it is undesirable to flood the stem base. It has been shown that anoxia has very little effect on the water absorption of roots of intact barley plants, apart from an initial inhibition of short duration. The action of 1 × 10-5 M dinitrophenol (pH 6.0) is similar. Neither treatment kills the roots. It is possible that permeability is maintained by fermentation reactions © 1962 Oxford University Press.

Considerable uptake of phosphate by both the shoot and root has been demonstrated for young barley plants with their roots in anoxic culture solution at concentrations of 1 to 10 μM orthophosphate. Consideration of the free space and passive transpirational uptake indicates an accumulatory process, and the immediate efflux caused by respiratory inhibitors supports this. Shoot uptake is much less at higher external concentrations of phosphate and at o.I mM was only 14 per cent of the control. The root accumulation process was unimpaired at an external concentration of 1 μM phosphate when the whole plant was subjected to anaerobic conditions (shoot illuminated) but under similar conditions at a concentration of 100 μM a considerable efflux of phosphate occurred. Analysis of the fate of phosphate taken up from anoxic solution of phosphate (10 μM) indicated that there was a reduction in the level of inorganic phosphate after 4.5 h and steady rise in sugar phosphates up to 6 h with a marked increase in the levels of glucose-6-phosphate, fructose-6-phosphate, and the phosphoglycerate fraction. © 1962 Oxford University Press.

Thick slump breccias, interbedded with greywackes and argillites, are well exposed in shore platforms and cliffs at Halliday's Point, 230 km north of Sydney. They are unusual in two respects. Firstly, they were formed by submarine slumping of marine sediments initially deposited by turbidity currents and pelagic sedimentation. The slumping was initiated by minor tilting of the sea floor perhaps brought about by faulting or by volcanic activity. Secondly, it was the coarse sandy layers which proved the more unstable lithology and which failed by viscous fluid flow. The finer grained interbedded layers in the slump mass fractured and remained as blocks and slabs, some large in size, in a matrix of coarser sediment. The rocks at Halliday's Point were derived predominantly from a volcanic source. Measurement of slump folds suggests emplacement of the breccias from a north-easterly direction. © Taylor & Francis Group, LLC.
