In the summer of 1925 I paid a visit to Møen, a Danish island situated about 50 miles south of Copenhagen, for the purpose of studying the cliff sections.

The particular object of the investigation was to ascertain how far the structure of the disturbed deposits of Møens Klint corresponded with that of the disturbed deposits of the Hadleigh Road Area, Ipswich (17, 20, 23), where the structure is strikingly analogous to that seen in Arctic glaciers; and, further, to ascertain whether the laws of structure formulated from the combined study of Arctic glaciers and disturbed glacial deposits were applicable to the Danish sections (21).

During a preliminary traverse of the area I was accompanied by Mr V. Hintze, Inspector of the Geological and Mineralogical Museum, Copenhagen, and Mrs E. Mertz of the Danish Geological Survey, thanks to the courtesy of the Director, Dr V. Madsen.

Lønstrup is a small fishing village and summer resort, situated on the west coast of North Jutland, a few miles west of Hjørring in the district known as Vendsyssel. The country generally is low and treeless, but is noted for its comprehensive schemes of land reclamation, and the scientific development of its agriculture.

In the neighbourhood of Lønstrup the monotony of the country is relieved by two low hills, the one, a little inland, is known as Vennebjerg, the other, known as Rubjerg Knude, lies some 2 miles to the south-west and is dissected by the coast-line, the apex of the hill being marked by a lighthouse. These two adjacent hills formed islands in the Yoldia Sea.

The coast-line has a uniform north-east, south-west trend, and cliffs occur from Lønstrup to Lokken in the south-west, a distance of between 7 or 8 miles, the cliff-scenery being generally similar to that of the Norfolk coast near Cromer.

Middle and Lower Deeside lie within the belt of injection and high-temperature metamorphism made famous by the pioneer researches of Mr George Barrow. In this paper are recorded the results obtained from a study of Cromar, an area small enough to admit of detailed petrographical treatment and yet large enough to exhibit a considerable variety of igneous and metamorphic phenomena. Of the three great phases of igneous activity there displayed, one is older than the epoch of maximum crustal movements, the second is closely connected with these, and the third is later; the rocks of each period have their own quite definite chemical, petrographical, and geological characteristics. Whilst here most attention will be directed towards the second group, that associated with the movements, an account of the other two groups will be given adequate for a discussion of the full igneous history of the area.

The object of this research was to compare the feeding mechanism of Nebalia with that of Hemimysis described by Miss Manton and myself (1927). The observations of the living animals were made partly at Naples while I was occupying the Cambridge University table, and partly at Plymouth where I had the use of the London University table.

The methods used in determining the feeding currents were the same as those used for Hemimysis (Cannon and Manton, 1927). To obtain a ventral view of the trunk limbs, I simply held the living animal upside down, gripping the abdomen with a pair of forceps, and in this position it would feed for a long time. I found it possible even to remove the entire carapace without killing the animal or upsetting the normal movements of the limbs.

In view of the frequent appearance, even in technical literature, of the old-fashioned idea that the lung of the tetrapod has evolved out of the air-bladder of fish, further work on the morphology of the air-bladder seems desirable. The theory of an air-bladder origin of the lung was brought forward by Boas, who based his view on purely theoretical arguments, which have, however, not found support in the facts brought to light by the advance of our knowledge of the embryology of the more archaic vertebrates.

Gigha is a little-visited island off the western coast of Kintyre and between the latter and the island of Islay. It lies about 5¼ miles south-west of West Loch Tarbert, and a little over 1½ miles from the nearest point of Kintyre where the mainland runs out for 1½ miles in the low, sandy, raised beach of Runahaorine (figs. 1 and 10).

The island is 6 miles in length from north-east to south-west, and has a greatest breadth of 2 miles. All round it are innumerable smaller isles, all elongated in the same direction as Gigha. Of these the most important are Cara, 1 mile from north-east to south-west by ½ mile in breadth, and Gigalum, ½ mile by ⅕ mile, and Craro, which is smaller still (figs. 2 and 10). The island forming Ardminish Point, on the eastern coast of Gigha, and Eilean Garbh, at the north-eastern end, will be dealt with here as if they were part of the main island, since at low tide they are connected with it by sandy isthmuses.

The collection of echinoids, which is the subject of this report, was made by Mr R. A. Farquharson, M.A., M.Sc., F.G.S., Government Geologist, during his survey of British Somaliland in the year 1923–24. The collection was presented by the Colonial Office to the Geological Department of the British Museum, and the Keeper, Dr F. A. Bather, F.R.S., has been good enough to allow me to examine and describe these interesting specimens. I have been fortunate in having beside me for comparison the echinoids from Somaliland in the Hunterian Museum, which were collected by Mr B. K. N. Wyllie, B.Sc., F.G.S., and Dr W. E. Smellie, and through them presented by the Anglo-Persian Oil Company. I take this opportunity of expressing my thanks to Professor Gregory for his interest in the collection and for much kind help.

Among the commonest and most abundant plant-remains in the Carmyllie and Cairnconon Beds of the Caledonian Lower Old Red Sandstone are branched linear axes about 2 mm. in width. These often occur in a fragmentary condition, but more connected portions demonstrating the morphology of the plant are also found. Though often associated with Parka and Nematophyton, the plant known as Zosterophyllum myretonianum is usually readily recognisable by its definite outline and uniform diameter, by its modes of branching, and by the remains of structure which it sometimes retains. As will be seen below, the axis of this plant was traversed by a single median strand that was composed of tracheides. Zosterophyllum is thus of special interest as the most ancient vascular plant known from British rocks. Some other plant-remains that may be confused with it have also been met with, though less commonly. These will be briefly considered, not merely for this reason, but on account of the very different and peculiar type of structure they exhibit.

Harris is supposed to derive its name from the Gaelic “na hardibh,” a designation signifying “the heights.” The term is appropriate in that the most mountainous parts of the Long Island lie within its boundaries.

South Harris forms a natural geographical division for it is divided, from North Harris by a narrow neck of iand at Tarbert separating the eastern from the western seas. This isthmus is less than half a mile across. In addition to South Harris proper, this memoir deals also with the Isle of Scalpay and neighbouring islets off the north-east coast, the Isle of Taran-say on the north-west, and several islands off the south-west coast in the Sound of Harris, of which the principal ones are Ensay, Killegray, Groay, Lingay, and Gilsay.

The shallow synclinal fold termed the Dalmahoy syncline is situated between the north-western flank of the Pentland Hills and the Murieston fault, the most southerly of the five important easterly and north-easterly dislocations which traverse the oil-shale field of West Lothian. The core of the syncline is occupied by rocks belonging to the lower division of the Oil-Shale Group of the Lower Carboniferous. Intervening between these and the Cement-stone Group is a volcanic zone, probably on the same horizon as the Arthur's Seat lavas, consisting mainly of mugearites and basalts which show their greatest development in the Corston Hill district. Along the whole of the southern limb of the syncline is an extensive spread of Upper Old Red Sandstone, but this formation is almost entirely cut out in the northern limb by the Murieston fault, appearing only in the core of a small anticline near Selms.

The present investigation was undertaken to throw some light upon the nature and mode of action of the peripheral nervous mechanism of the uterus.

Previous work has demonstrated that the organ, like other viscera, has an autonomic action. That the uterus and vagina can function independently of the central nervous system has been shown both clinically and experimentally by Sir J. Y. Simpson (1), Goltz (2), Riemann (3), Rein (4), Kabierske and Heidenhain (5), Masius (6), and Kurdinowsky (7).

The nervous mechanism of the uterus may be divided into a central and a peripheral part.

Two contrasted oceanographical regions are dealt with in this paper, the fauna of the eastern Pacific being distinct from that of the Marquesas, which are the farthest outliers of the western ocean. In each of these two regions again are two divisions of markedly different ecology, physical conditions in the Galapagos being as great a contrast as could well be to those of the coast of Panama, while the Marquesas Islands differ from their neighbours farther west, which are either atolls, or high islands surrounded by broad reefs, in being without coral deposits of any considerable size, and certainly no true reefs. The corals afford a striking example of the contrast between the two main regions; in Panama the only abundant coral is Pocillopora, in the Marquesas the only “reef” is of Porites, and the other deposits depend upon this genus for their existence. Several species of Pocillopora are abundant in the Marquesas, but are all distinct from those of Panama.
