Last Summer, when I travelled in South Africa with the British Association, I examined the diamantiferous gravels on the Vaal River near Kimberley. During this visit Mr. Krumbelt, apothecary in Barkly West, had the kindness to give me three fossil teeth which he had found in the local gravels. Nos. 1 and 2 were obtained from the so-called breakwater workings of the river-side, while No. 3 was found in the Waldeck Plant in the higher terrace of gravels at an elevation of 60 to 80 feet. The state of preservation of all these teeth is that of real fossil remains.

The corals described in this report were collected by members of the Egyptian Geological Survey, and were sent to London in September, 1899. I then examined most of the specimens, and submitted a preliminary report to the effect that they belong to three horizons:—

Mr. John Smith, of Kilwinning, has been fortunate enough to obtain from the Lower Limestone series of Auchenmade, Ayrshire, a specimen of the left valve of Aviculopecten semicostatus, Portlock, sp., which shows the hinge plate and interior most perfectly preserved. Hitherto a study of the hinge plate of Aviculopecten has been made from specimens which were merely casts of the interior, and consequently it has been impossible to observe that portion of the hinge plate immediately interior to the umbo. The Auchenmade specimen advances our knowledge of the anatomy of the genus, and establishes a character denied for it by its author, M'Coy.

The Eleidæ are a very natural family of extinct Polyzoa, remarkable for exhibiting characters relative to both the groups Cyclostomata and Clieilostoraata. It is not, however, the affinities of this with other families that are here considered, but a means of determining by zoæcial characters the reptant ‘ species’ within the group; the validity of the ‘genera’ forming it; the occurrence in England of one of the ‘genera’—Semimultelea— hitherto unrecorded from Britain; the description of a new species of this ‘ genus’; and the phenomenon of local groups of zoæcia having characters differing from those of the rest of the zoarium.

Attention has lately been called by M. Marcellin Boule to the production in cement-mills in the Commune of Guerville, near Mantes, of all the more characteristic forms of Eoliths, and of these he has given photographic reproductions. The evidence for the necessarily artificial shaping of Eoliths had for many years been questioned by him, because he had found chipped flints of this character in the midst of Oligocene or Miocene beds in Auvergne and in the Velay; and it seemed imprudent to infer the existence of man in those early stages of the Tertiary period in the absence of osteological evidence.

Downwashed sand and mud much obscured the section, but the clay appeared to be definitely continuous, while the chalk might be continuous under the mask of mud, but did not seem likely to be so. The section suggested very strongly a flat sheet of clay pushed at a level some way below the beach against a backward sloping and then overarching surface (e.g. the side of a cave), which it had followed until doubled back upon itself.

IN his Presidential Address to the British Association, South African Meeting, 1905, Professor G. H. Darwin points out that the presence of radio-active materials in small proportion in the sun would serve to explain the present radiation, and “that concentration of matter is not the only source from which the sun may draw its heat.” Professor Darwin goes on to explain how this enables us to extend the possibilities of geological time beyond that to which some physicists would limit us.
