By means of measurements of the direction of magnetization, talus may be distinguished from rock which has remained in situ. A criterion has been developed for the conditions under which the boundary between talus and rock in situ can be identified. This method is particularly useful when the upper portion of the rock in situ is broken and weathered and it has been applied with success to a scarp in the dolerite of the Western Tiers in Tasmania. Here the results suggest that in the upper part of the talus the jointed blocks have definitely fallen into a sub-horizontal position, whereas at lower levels they are only slightly tilted.

A short description is given of Cambrian and Ordovician fossils from near the top of the Hecla Hoek succession in Ny Friesland and the relations with other areas is briefly discussed.

The occurrence of low Namurian plants in the Neath Valley is noted. It is believed that they show the presence of the Eumorphoceras Stage. This revision of age in relation to the Namurian-Avonian junction is briefly discussed.

The Woolridge Terrace gravels of the lower Severn are re-examined, and certain high-level gravels west of the Severn valley examined for the first time. It is concluded that the deposits are of two different ages. The older series is probably the outwash of a Severn valley glacier, the younger was laid down by a stream coming from the Silurian hills near Ledbury. A Gipping age is suggested for both.
