In 1862, Professor T. Rupert Jones published some notes on a careful microscopical examination of five samples of clay from the Bracklesham beds of Bracklesham, Selsea, and the Isle of Wight (?). This paper gave a good idea of the systematic methods which could be employed in working over a sample of fossiliferous material, especially when rich in microzoa, and the results of which are often of great use to geologists and palæontologists.

Having already discussed the contents, the distribution, and general facies of the widely-spread deposits of Eastern England, which together make up the series classed as Glacial beds, namely, the Post-Tertiary clays, sands, and gravels which have been supposed to attest an Ice period ; and also set out the reasons why, to myself and perhaps to others, the attribution of the surface-beds to such an origin is irrational and impossible (irrational because the theory involves our overlooking nearly every feature of these beds in order that we may explain one or two difficulties in them; and impossible because, so far as ice can be judged by the tests of ordinary mechanics, it is incapable of performing the kind of work which has been demanded of it by those who explain these beds by the intervention of ice in any form)—I will now turn to one element in the beds which still remains to be examined, namely, the foreign stones.

A year ago, by the decision of the Council of the British Association, there was sent to the Museum of Practical Geology a large collection of photographs mainly taken with a view of illustrating, in the most permanent and unbiassed way at present possible, the features and phenomena of geological interest in the United Kingdom. The project of forming such a collectionoriginated with Mr. O. W. Jeffs in 1888, when he read a paperon the subject at the British Association at Bath, in which hepointed out the utility of such a collection and the necessity for forming it. When a committee was appointed in the followingyear he undertook the management of the work, and he has carriedit ou for seven years with indefatigable industry and scrupulou scare, only relinquishing it when the size of the collection beganto exceed the capabilities of private control, and when his own lackof leisure no longer permitted him to devote the requisite time andattention to its custody.

The recent find by Mr. Stebbing, F.G.S., of two large boulders of granite in the Middle Chalk of Betchworth (Surrey), has called to mind the various discoveries of boulders which had previously been made in the same marine formation by other observers.

Professor J. C. Branner has written a most interesting and valuable treatise on the “Decomposition of Rocks in Brazil,” of which he has kindly sent me a copy. All who want to study agencies of decomposition and denudation as they act in tropical countries cannot do better than read Professor Branner's clear and well-digested exposition, illustrated as it is by excellent reproductions of photographs and by figures and diagrams.
