In the Report on the Geology of Trinidad the Government geologists described a series of sandstones and shales extending across the island from east to west, and occupying an extent of about 97 square miles. The distribution of the formation, which has been named the “Older Parian,” is in the manner of an irregular band of from 1 to 4 miles in breadth, traversing the island in an easterly direction from the Gulf of Paria at Pointe à Pierre. This band terminates rather abruptly before reaching the east coast, but the formation reappears here and there near the south coast along a line parallel to the main band. The formation is only exposed for a short distance on the shores of the Gulf of Paria; but it has been found to cover a large area, and to be extensively developed on the continent of South America. The fossils found by the geologists in Trinidad seem to have been few, and for the most part indeterminable. They however obtained fossils from the same formation at Cumana, in Venezuela; and these remains led to the belief that the Older Parian was probably of Neocomian age. During a short visit to Pointe à Pierre I obtained several fossils, which have enabled me to make the observations detailed in the present paper.The section given by the Government geologists of the Older Parian deposits at Pointe à Pierre is taken on the south side of the point, which I have not had an opportunity of examining carefully. The geologists do not seem to be able to give much attention to that portion of the deposits which is exposed on the north side of the point, and I hope that the present paper, in so far at least as it relates to the fossils, may in some measure supply the deficiency.

In 1870 the Government of the day had behind it the stronger party in the country; and among its followers in Parliament were the two members for the City of London. Pass a quarter of a century, and come to the Government brought into power by the general election of 1895. Exactly the same two things may be said of it; it too had behind it the stronger party in the country; it too numbered among its followers in Parliament the members for the City of London. Only, whereas the Government of 1870 was Liberal, the Government of 1895 was Conservative. That quarter of a century had witnessed the transfer of the City of London's political allegiance from Liberalism to Conservatism; and therein the City's opinions corresponded to those of the business and moneyed classes generally. So it was, not only in the south of England, but also in the Midlands and Lancashire; though not yet at all to the same extent in Yorkshire, the north-east coast, or Scotland.

In het tweede deel van zijn bijdrage 1830: van de Belgische protonatie naar de natiestaat, over de gebeurtenissen van 1830-1831 als slotfase van een passage van de Belgische protonatie doorheen de grote politiek-maatschappelijke en culturele mutaties na de Franse Revolutie, ontwikkelt Lode Wils de stelling dat de periode 1829-1830 de "terminale crisis" vormde van het Koninkrijk der Verenigde Nederlanden. Terwijl koning Willem I definitief had laten verstaan dat hij de ministeriële verantwoordelijkheid definitief afwees en elke kritiek op het regime beschouwde als kritiek op de dynastie, groeide in het Zuiden de synergie in het verzet tussen klerikalen, liberalen en radicale anti-autoritaire groepen. In de vervreemding tussen het Noorden en het Zuiden en de uiteindelijke revolutionaire nationaal-liberale oppositie vanuit het Zuiden, speelde de taalproblematiek een minder belangrijke rol dan het klerikale element en de liberale aversie tegen het vorstelijk absolutisme van Willem I en de aangevoelde uitsluiting van de Belgen uit het openbaar ambt en vooral uit de leiding van de staat.________1830: from the Belgian pre-nation to the nation stateIn the second part of his contribution 1830: from the Belgian pre-nation to the nation state, dealing with the events from 1830-1831 as the concluding phase of a transition of the Belgian pre-nation through the major socio-political and cultural mutations after the French Revolution, Lode Wils develops the thesis that the period of 1829-1830 constituted the "terminal crisis" of the Kingdom of the United Netherlands. Whilst King William I had clearly given to understand that he definitively rejected ministerial responsibility and that he considered any criticism of the regime as a criticism of the dynasty, the synergy of resistance increased between the clericalists, liberals and radical anti-authoritarian groups in the South. In the alienation between the North and the South and the ultimate revolutionary national-liberal opposition from the South the language issue played a less important role than the clericalist element and the liberal aversion against the royal absolutism of William I and the sense of exclusion of the Belgians from public office and particularly from the government of the state.

The distribution of Mesolithic sites in Wales is controlled to a great extent by the terrain, for physiographically, Wales is a highland block defined on three sides by the sea and for the greater part of the fourth side by a sharp break of slope. Geologically the Principality is composed almost entirely of Palaeozoic rocks, of which the 600-foot contour encloses more than three quarters of the total area. There are extensive regions above 1,500 feet and 2,000 feet and in the north the peaks of Snowdonia and Cader Idris rise to 3,560 feet and 2,929 feet respectively. Indeed North Wales consists of an inhospitable highland massif, skirted by a lowland plateau and cut deeply by river valleys, providing only limited areas for settlement. The hills and mountains of Snowdonia with their extension at lower altitudes into the Lleyn Peninsula, and the ranges of Moelwyn, Manod Mawr, Arenig Fach and Cader Idris, are discouraging obstacles to penetration, save for a short distance along the river valleys. To the east of these peaks are extensive tracts of upland plateau dissected by rivers, bounded on the west by the vale of the river Conway and cleft by the Vale of Clwyd. To the east of this valley lies the Clwydian Range and further again to the east these uplands descend with milder contours to the Cheshire and Shropshire plains.To the south the district merges into the uplands of Central Wales, which are continuous until they are replaced by the lowland belt of South Wales.

The new material on which this paper is based has lately been received through Mr. D. Ferguson, who recently investigated the geology of the island, and collected the rocks described in an earlier paper. It consists of twenty-seven rock specimens from the south-eastern end of the island, between Cape Disappointment and Cooper Island, and nine specimens from Gold Harbour on the north-east coast between Cooper Island and Royal Bay. All these were collected by the staff of the South Georgia Co., Ltd., under the instructions of Mr. Th. E. Salvesen, managing director, of Leith.

The map of South America shows Peru as a rather long, narrow country, broadening at the north, and presumably tropical in climate judging by its position just south of the Equator, but with high mountains close to the coast. But it does not show the cold ocean current coming from the south—the Humboldt Current—or ar least we are not accustomed to noticing such presumably minor features, even though in the case of Peru, this is equal in importance with the mountains in determining the climate of the country and every factor that the climate may affect.

On De La Beche's Geological Survey Map of Cornwall are three colours representing the associated rocks at, and on each side of the Manacle Point. The Point itself and for a considerable distance south of it is represented as a greenstone. Partially encased in the greenstone and to the south of it is gabbro, which forms the main mass of this rock in the Lizard district. On the north side of the greenstone which forms the extreme south wall of Porthonstock Cove is hornblende-schist, which with some serpentine and other rocks terminates against the killas, or slates near Porthalla.Several observers with seeming good reason have drawn attention to the fact that the greenstone as represented on the map is made to cover much too large an area to the south, and that any one walking from this direction, or the reverse, finds gabbro where the former rock was expected to occur.

ABSTRACT Diplodon granosus was one of the first freshwater mussels to be described for South America. However, the status of the species was confusing for a long time, receiving different taxonomic treatments. In this paper, we redescribe the shell, with new data on the soft parts and information on the distribution and conservation of D. granosus, a rarely recorded species. The shell is thin, not inflated; the macrosculpture is composed only by granules that cover the whole shell, not forming bars; the microsculpture comprises short spikes. In the soft parts we highlight the few, weak and irregularly distributed lamellar connections of the outer demibranch and some features of the stomach, such as the distally enlarged minor typhlosole. There are records of D. granosus over a large area of South America, from Guiana to Argentina. However, most of these records are related to other species and the distribution of D. granosus is restricted to the north of South America in the basins of the Amazonas and Orinoco rivers, and coastal rivers in between. Despite this wide distribution, the species occurs in specific habitats, mainly streams (igarapés), resulting in an extremely fragmented occurrence. Thus, any disturbance to these habitats can threat this freshwater mussel.

Urban furniture can be defined as aesthetics and comfort elements that reflect the identity of a city and enable the urban space to become livable. Urban furniture is an important element of the city in order to improve the quality of urban life, to create a comfortable and reliable environment and to meet the needs of the users in the best way. For designing these elements, the social, economic, cultural and architectural structure of the city should be considered and evaluated. It is important to adapt the urban furniture to the urban texture and to the cultural structure achieving an urban identity, in order to ensure the survival and sustainability of the historical environments. In this study, a study was carried out in the context of urban furniture in Nicosia Walled City, which has many architectural cultures with its historical texture. In this context, firstly the concept of urban identity and urban furniture was explained and then, information about urban furniture was given in historical circles with urban furniture samples from different countries. As a field study, a main axis was determined and the streets and squares on this axis were discussed. These areas have been explored starting from Kyrenia Gate in North Nicosia; İnönü Square, Girne Street, Atatürk Square, Arasta Square, Lokmacı Barricade and on the south side Ledra Street and Eleftherias Square. In this context, the existing furniture in the North and South were determined and evaluated in terms of urban identity accordingly. As a result, it can be suggested that the existing street furniture equipments, especially on the north side, do not have any characteristic to emphasize the urban identity. According to the findings, it was determined that the urban furniture in the streets and squares on the north side is generally older and neglected, and does not provide a unity with the environment, whereas on the south side, these elements on the street and square are relatively new, functional and environmentally compatible.Key words: urban furniture, historical environment, urban identity, Nicosia Old City

In plan the walls surrounding the Acropolis of Sparta form an irregular oblong, terminated to the east and west by two small hills which formed citadels or outlook points. Though no single complete part remains, and in many places the walls are levelled to the ground, the lines can still be traced fairly completely. (Plate VIII. 3.)At the south eastern corner are the ruins of a Roman Stoa of the Imperial period (A). They shew a series of small compartments (Fig. 1), covered with barrel vaults, ten on either side of three larger central rooms, which are roofed with crossgroined vaults and large semicircular niches at the back. The ground on the north side is as high as the vaults and originally must have formed a terrace overlooking the street on to which the Stoa opened on its south side.

A most remarkable production of nature in the island of Trinidad, is a bituminous lake, or rather plain, known by the name of Tar Lake; by the French called La Bray, from the resemblance to, and answering the intention of, ship pitch. It lies in the leeward side of the island, about half-way from the Bocas to the south end, where the Mangrove swamps are interrupted by the sand-banks and hills; and on a point of land which extends into the sea about two miles, exactly opposite to the high mountains of Paria, on the north side of the Gulf.
