The name of Geikie has become as familar to present-day geologists as those of Murchison, of Sedgwick, or of Lyell were to our immediate prodecessors.

Notices and portraits of his elder brother, Sir Arehibald Geikie, K.C.B., the President of the Royal Society, have already appeared in the Geological Magazine (see Vol. for 1890, Pl. II, pp. 49–51, and 1907, Pl. I, pp. 1–2); it is high time to present that of the younger brother, Professor James Geikie, who occupies the leading place in our science and in geography in Edinburgh and itys University, and is known every where also by his published works, especially by his contributions to Glacial Geology.

Avicularia of what I have called the Lesueuri-type are not confined to Membranipora. There are at least two species provided with them which come nearer to Semieschara.

In the April number of this Magazine a review appeared of Colonel Burrard's memoir on the origin of the Himalaya Mountains. The writer, Sir T. H. Holland, in it refers to a paper of mine originally published in the Phil. Mag., and subsequently in an amended form as Appendix No. 1, 1905, Indian Survey Papers, professional vol. xviii. I shall be glad to make a few remarks upon the subject. After duly crediting me with having partially anticipated the results now obtained by the Survey, by calculating the deflection of the plumb-line in North India which would follow from my theory of mountain compensation by a ‘root’ extending to a depth of about 29 miles, the reviewer continues— “The variations now observed are, however, more violent than those expected by Mr. Fisher, for the northerly deflections of the plumb-line decrease to zero at a distance of about 15 instead of over 60 miles from the visible foot of the hills.” I would reply that I have not calculated the deflection at 15 miles, and it is not safe to guess a priori what it would be. The numerical calculation for a given distance is tedious, and I could not now undertake it.

One of the most important and most interesting features of the geology of the Cambridge district is the deposit at Barrington, so widely known for its richness in mammalian remains. This bone-bed has been described many times, and the literature is large. Most of the descriptions, however, confine themselves chiefly to the organic contents, mentioning briefly the character of the larger stones and pebbles, and saying little or nothing about the nature of the finer matrix in which these are embedded.

Lystrosaurus, Cope = Ptychognathus, Owen (non Stimpson), has long been known from isolated but often perfectly preserved skulls. Quite recently the reception of a magnificent skeleton by the Albany Museum, Grahamstown, enabled me to give a restoration of the animal. In this drawing the hand and foot were drawn from incomplete non-associated remains. Whilst travelling in South Africa, with the aid of a grant from the Percy Sladen Trustees, I collected on the farm Klip-kuil a fragmentary skeleton of Lystrosaurus, much of which was so rotten that it could not be preserved, but which included a complete left fore-limb. This was developed by myself and was found to lie in its natural position with the digits very strongly flexed, except that the metacarpals were slightly separated laterally. It is represented in Text-fig. 1, with the humerus, radius, and ulna in the position in which they were found, and with the fingers extended. The humerus is not very well preserved, but agrees exactly with the excellent example figured by Owen, Catalogue of South African Fossil Reptiles. It is of the usual Anomodont type, with a very powerful deltoid crest extending half-way down the shaft, and a much expanded lower end with a large entepicondyle. There is a large entepicondylar foramen,

On looking over a miscellaneous collection of animal bones from a cave in North Wales, sent to me for identification by Mr. John H. Morris, of West Bromwich, I was pleased to discover the remains of the lynx, and as our knowledge of the occurrences of this animal in the British Isles is so scanty, it seems to me to be of some interest to record the present discovery.

Bathymetric surveys have revealed much that is very interesting concerning the ocean floors, not only as regards the deeper portions, but also as concerns the continental shelves. Hull has constructed charts of the North Atlantic and shown that many of the shallower areas are of such a form as to suggest that they were originally portions of existing river-basins, and that the submerged valleys may be traced along the sea bottoms to depths of more than a thousand feet round the present continents. Similar submerged troughs have also been noted along the margin of the Asiatic continent. Two such well-marked channels occur in the ocean at the mouths of the Indus and Ganges. Indeed, the phenomenon would seem to be one common to all the continental shelves.

The result of the Tendaguru expedition to German East Africa has been the discovery by Drs. W. Janensch and E. Hennig of some forty Dinosaurs, ranging in size from forms larger than Diplodocus to ones as small as a pointer dog; these finds may be extended since Dr. H. Reck has proceeded to the locality with the intention of digging for a further year. In a paper by Dr. Hennig on the possible extension of the Dinosaur deposits this author calls attention to the discovery by the late Dr. W. G. Atherstone of Dinosaur remains in the Wood Bed (Lower Cretaceous) of Bushman's River. In his description, published in the Eastern Province Magazine, Grahams town, 1857, Dr. Atherstone states that a large part of the skeleton as well as the skull was discovered, but the only parts so far describe are two skulls named by Owen Anthodon serrarius. Very little is known of this form, and Zittel places it in the Pareiasauridae a a Karroo reptile. Dr. R. Broom described another Dinosaur from the same beds at Despatch, near Port Elizabeth, under the name Algoasaurus Bauri. Messrs. Eogers and Schwarz mention Dinosaur bones as occurring in the sandy beds along the Bezuidenhouts River in Uitenhage, and some detached bones and teeth from these beds are exhibited in the Albany Museum, Grahamstown. All these remains are of comparatively small animals for Dinosaurs. In the recent Whitsuntide holidays Professor E. H. L. Schwarz took his students to the Bushman's River, and in Dr.
