The Riebeckite-Orthophyre of the Holy Isle.—Four Occuxrences of acid and sub-acid igneous rocks containing the rare soda-amphibole riebeckite have been recognized in Great Britain, of which that of Ailsa Craig is the best known. The occurrences of Ailsa Craig and Mynydd Mawr, Carnarvonshire, are riebeckite-microgranites or paisanites. They contain ragged moss-like areas of riebeckite, together with microphenocrysts of quartz and alkalifelspar, in a microcrystalline groundmass of quartz and felspar. Riebeckite was also found by Dr. Teall in the granophyre of Meall Dearg and the neighbouring area of Druim an Eidhne, Skye. Harker described the riebeckite in these rocks as occurring in two forms, one having the usual ragged, sponge-like appearance, and the other being idiomorphic, the faces in the prism zone being well-defined, but with irregular terminations. The fourth occurrence differs somewhat from the others. This rock occurs as an intrusion into the Upper Old Red Sandstone, or Calciferous Sandstone of Easter Eildon Hill, Melrose, and was described by Barron as riebeckite-trachyte or phonolite. It consists principally of sanidine, occurring both as microphenocrysts and in the groundmass, with interstitial patches of riebeckite, and a little nepheline. Harker describes the rock as an orthophyre.

The following pages are based on the last six months of 1948 which the writer spent in England, France and Italy. During this period Marshall aid had begun to bear certain fruit. On the other hand the international situation, already bad at the opening of the period, had deteriorated cumulatively as time passed. The Berlin deadlock, a symbol of the will of East and West, continued as before; and not even the beginning of a solution was reached at the United Nations assembly in Paris in die autumn. All over Europe people were preoccupied widi the economic crisis; but also by the direat of a new war. A military committee composed of Great Britain, France and Benelux was formed in the autumn under the chairmanship of Marshal Montgomery. There remained problems about this committee's effectiveness as well as about the extent to which other proposals for Western union were practicable at present. While in each country in Western Europe common people and politicians are talking more about union than ever before, in practice separatist tendencies in each shrunken western nation are still at work and travel to, or independent contact with, neighboring countries is a far more difficult business today than it was in 1939.

The previously ignored model of Greek colonisation attracted numerous actors from the 19th century British empire: historians, politicians, administrators, military personnel, journalists or anonymous commentators used the ancient paradigm to advocate a global federation exclusively encompassing Great Britain and the settler colonies in Canada, Australia, New Zealand and South Africa. Unlike other historical templates, Greek colonisation could be viewed as innovative and unspent: innovative because of the possibility of combining empire and liberty and unspent due to its very novelty, which did not contain the ‘imperial vice’ the other models had so often shown and which had always led to their political and cultural decline.

This article investigates patterns of personal pronoun usage in four texts written by women about women's rights during the 1790s: Mary Wollstonecraft's A Vindication of the Rights of Woman (1792), Mary Hays' An Appeal to the Men of Great Britain (1798), Mary Robinson's Letter to the Women of England (1799) and Mary Anne Radcliffe's The Female Advocate (1799). I begin by showing that at the time these texts were written there was a widespread assumption that both writers and readers of political pamphlets were, by default, male. As such, I argue, writing to women as a woman was distinctly problematic, not least because these default assumptions meant that even apparently gender-neutral pronouns such as I, we and you were in fact covertly gendered. I use the textual analysis programme WordSmith to identify the personal pronouns in my four texts, and discuss my results both quantitatively and qualitatively. I find that while one of my texts does little to disturb gender expectations through its deployment of personal pronouns, the other three all use personal pronouns that disrupt eighteenth century expectations about default male authorship and readership.

I beg leave to offer to your Lordship and the Society a Description of a Roman Altar lately dug up in the neighbourhood of Aldston Moor, in Cumberland, near a military road, and not far from a great Roman station. The altar is three feet high, sixteen inches wide, and eight thick. It is divided into three compartments, the capital, the square or plane, and the base. On the top is an oval cavity one inch and a half deep, and about nine over by six, in which the wine, the frankincense, and the fire were placed, and was called Thuribulum, the censer, or the focus; but this hole is not on all the Roman altars found in Great Britain. On the sides however of the one I am describing are two bass-reliefs, representing on one part the infant Hercules strangling two serpents (as he is seen on a silver coin of Croton in Italy), and on the other the god in all his strength about to combat the serpent in the garden of the Hesperides (as he appears on a coin of Geta struck at Pergamus).

The nomenclature of the fishes of the Old Red Sandstone of Great Britain, with the exception of the Cephalaspidæ, revised some years ago by Professor Lankester, is at present in a very unsatisfactory state. A vary large number of the species named by Agassiz, as well as by McCoy, were undoubtedly founded upon deceptive characters, due partly to different modes of preservation in different rocks, partly also to those apparent variations in external form, which are inevitable in such ancient fossil fishes devoid of a fully ossified internal framework, without which the original outline cannot be expected to be constantly preserved. In specimens from one locality the external ganoid surface of the scales may be well shown, in those from another it may be constantly hidden or obscured, while the proportional measurements in the very same species may vary infinitely, by the fish being lengthened out, or shortened up by changes, which have occurred after death or during the consolidation of the enclosing rock. These and kindred sources of fallacy can only be guarded against by long experience in deciphering such remains, coupled with the examination of an immense number of specimens.

This chapter examines whether status concerns lead decision makers to value status more highly by looking at three separate sets of decisions: Russia's decision to aggressively back Serbia in the 1914 July Crisis, Britain's decision to collude with Israel and France in launching the 1956 Suez Crisis, and Gamal Abdel Nasser's 1962 decision to intervene in the Yemen Civil War (and continue to escalate through the rest of the decade). These cases broadly substantiate the patterns found in the Weltpolitik case—decision makers tend to value status more highly due to status concerns—while highlighting the plausibility of several new mechanisms. They also show that status concerns are not confined to European countries, great powers or states in the pre-World War I era. Finally, they reveal the other side of status concerns: state behavior designed to salvage or defend status rather than increase it.

This article deals with the background for the November treaty of 1855 between Great Britain and France on the one hand, and the United kingdoms of Sweden and Norway on the other. The November treaty explicitly pointed to Russia as a potential aggressor against Norway and Sweden and offered these states protection by the two Western Powers. The author elucidates the prerequisites for the conclusion of the treaty, and its role as a first step in Norway’s orientation between East and West — and a foreboding of independent Norway’s foreign policy (from 1905).

That silica appears as a constituent mineral of igneous rocks in two distinct phases, viz. quartz and tridymite, has been known for some time. The writer is not aware that any explanation has been offered which would indicate the conditions determining the appearance of one or the other in a cooling fused rock-mass. He now proposes to describe certain experiments made with a view to explain why it is that though the free silica generally appears as quartz, yet occasionally, as in certain trachytes, it crystallizes out as tridymite.
