I have been asked to make a written contribution to the discussion, but have nothing new to say. My views will be found in the 1961 version of The Earth and in my lecture to the Royal Astronomical Society last October, which will be published in their Quarterly Journal. My main points are that the only type of imperfection of elasticity considered in convection and drift theories is the elastico-viscous law, which has been found to lead to numerous contradictions when confronted with actual evidence. Different phenomena led to values of the effective viscosity differing by factors of millions. On the other hand, a modified law, chosen to fit two quantitative data and applied far beyond the range of periods related to those data, has steered its way nicely among the other evidence for some sort of imperfection of elasticity, without giving any contradiction. But it does forbid convection and continental drift. I should be disposed to agree that inability to explain an alleged phenomenon is not necessarily a disproof of that phenomenon; but it does require a higher standard of scrutiny of the evidence for that phenomenon. The standard actually applied to evidence for continental drift seems to be considerably lower than is usual for a new phenomenon, and is not associated with any alternative explanations of things that can be explained.

In the Fourteenth Volume of the Transactions of the Royal Astronomical Society will be found a full account of the Cavendish apparatus, and of the mode of experimenting followed by Mr. Baily. It will therefore not be necessary for me, in this place, to enter into any detail as to the different parts of the instrument, and the various precautions adopted in order to avoid that singular source of error 'currents of air in the torsion box arising from unequal temperature,’ which had been discovered by Cavendish. It will be sufficient for me to state that all the arrangements are of a highly satisfactory kind, and that I am of opinion that no aerial currents could have existed in the torsion box. The deduction of the mean density of the earth from the observed vibrations of the balls influenced by the torsion force and the attraction of the masses, is founded on a mathematical theory of the motion of the balls given by the Astronomer Royal, Mr. Airy ; and as this theory is certainly insufficient to account for the discrepancies, it will here be necessary to give a brief sketch of it.

Goals And Objectives

This study aims to evaluate the role of Maahad Tahfiz ADDIN to produce huffaz in the State of Perak Darul Ridzuan based on the implementation of the Tahfiz Al-Quran curriculum with important instruments of collecting quantitative data (questionnaires). A survey method which was used involved 366 students from the Maahad Tahfiz Al-Quran ADDIN in the state of Perak who are randomly selected. The subjects of the study were students aged 13 years to 17 years old. A questionnaire was developed to collect the required data. The findings were analyzed descriptively by Statistical Package for Social Sciences (SPSS) Version 22.0. The results show that the implementation of the goals and objectives of the Quranic Tahfiz curriculum at Maahad Tahfiz ADDIN was the highest mean of 3.60. The conclusions from this study show that the goal and objectives of tahfiz are at a good level and can be further enhanced. On the other hand, the content of the curriculum and time allocation for the Quranic memorization should be given due attention and improvements so that Maahad Tahfiz ADDIN can actually filling the gap in producing more quality huffaz in the state of Perak Darul Ridzuan.

The One

In this paper we will describe the historical development of the Spanish doublet ante-antes (‘before’) and explore the question whether a process of exaptation is involved (cf. Lass 1990). We will argue that the final –s of antes, that originally marked the adverbial status of the word, in the course of time had become a kind of morphological ‘junk’ (cf. Lass 1990) and, subsequently, could be exploited in order to encode the semantic opposition between temporal meaning on the one hand, and adversative meaning on the other hand. However, based on quantitative data we will show that the incipient semantic redistribution over the course of the 16th century rather suddenly collapsed, leading to a differentiation between the prepositional ante and adverbial antes.

Post Hole

The rabbit shares one characteristic with the archaeologist—both dig into the earth. Hence the latter, contemplating some object or evidence revealed by his spade, may sometimes be viewing merely the result of the activities of a humbler but much more numerous type of excavator. Is he not warned to ‘always make sure that an apparent post-hole is not a rabbit- or rat-hole’? And does not Professor James Ritchie describe the rabbit as ‘a burrower and a vandal which makes short cuts through the neat layers and classifications of the excavator’? On the other hand, the rabbit's activity or lack of it may on occasion be of service; it was a long patch of virgin turf on Easton Down, untouched by rabbits or moles, which led Dr Stone in 1932 to remove the turf, thus revealing a layer of tightly packed flint nodules covering a Bronze Age urn-field. Hence no apology, we feel, is needed for an article on the rabbit in a journal primarily concerned with archaeological research; particularly as much of the article deals with the status of the rabbit in medieval times, a topic which has already figured briefly in ANTIQUITY.

Early Results

High-resolution simulations of the atmospheric and oceanic general circulations on the Earth Simulator are briefly introduced to a wider research and educational community. Some early results have been published and are reviewed in this article. The high-resolution simulations may have more information in certain aspects than observations while the simulations need to be validated. On the other hand, high-resolution observations in which uncertainties are unavoidable are now available. Possible close collaboration between observational and simulation research is proposed.

In the course of an investigation into the trajectories, or actual paths of air, by means of synoptic charts, which is still in progress,* it became apparent that the paths of air taking part in cyclonic dis­turbances near the British Isles when traced backward did not always originate in anti-cylonic areas, but followed a track skirting the neighbouring high-pressure areas and traversing sometimes a very large part of a belt of the earth in a direction more or less parallel to a line of latitude, and, on the other hand, air moving in the neighbour­hood of a cyclonic depression did not invariably seek the nearest baro­metric minimum, but sometimes passed on, leaving the circulation of the depression on the left hand.

1. In a previous communication submitted to the Royal Society on June 28th, 1861, and since published in their Transactions, I ventured to make a suggestion regarding the nature of that connexion which subsists between magnetic disturbances, earth-currents, and auroras. In this hypothesis the earth was viewed as similar to the soft iron core of a Ruhmkorff’s machine, in which a primary disturbing current was supposed to induce mag­netism. Earth-currents and auroras, on the other hand, were viewed as induced or secondary currents, caused by the small but abrupt changes which are constantly taking place in the strength of the primary disturbing current, these changes being very much heightened in effect by the action of the iron core, that is to say, of the earth.

AbstractThe trend toward the concept of humanity in political theory has arisen largely as a reaction against the mistreatment of vulnerable people such as immigrants. The issue of immigrants’ vulnerability has led political thinkers to ponder on how to apply the principle of humanity to the question of the treatment of immigrants. I would like to address this matter by examining two questions: what is humanity, is it a value property, or a virtue? Does it really matter if the means by which an immigrant immigrates is demeaning to his own humanity as a person? The most common or intuitive reply to these questions would probably be: ‘humanity’ is simply a value-bestowing property, so regardless of immigrants’ actions they are owed respectful treatment. The aim of this paper is to emphasise instead that ‘humanity’ should be conceived as a virtue of actual commitment to act on moral principles. I explore three different meanings of humanity. First, I discuss ‘humanity’ as the common ownership of the earth. Second, I discuss ‘humanity’ as a value property. Third, I discuss humanity as a virtue of acting, on the one hand, with humanity, and on the other hand, on moral principles.

In order to obtain the best possible seismic field record, it is indispensible on the one hand to know the response of the earth to the explosion, and on the other hand to operate the seismograph equipment with suitable settings.

The Difference

Our equations (3) and (4) are correct. They represent the difference between the attraction of the shell viewed from [Formula: see text], the outer radius of the shell, and [Formula: see text], its inner radius. (The attraction of the shell viewed from [Formula: see text] is zero.) On the other hand, equations (5) and (6) of Fahlquist and Carlson represent the difference in attraction of the entire earth from the same viewpoints and thus, as they say, include a free‐air gradient term. However, their equation (5) would be correct only if the mean density of the earth were equal to that of the shell, and the free‐air gradient obtained by their equation (10) is correct only under these circumstances.
