Many ways of measuring geological time have been attempted by various geologists of eminence; but however diverse their methods, so far as I know, all finally hinge upon either the rates of denudation or accumulation. It is urged as an objection to this that in past ages such actions have gone on more rapidly, and therefore the calculations based upon present rates are valueless. Physicists on the other hand have sought to put a limit to the age of the earth much below what geologists generally demand. Reasoning from certain data which are necessarily more or less hypothetical, they say, that from the thermal condition of the globe at present, it cannot be more than from ten to twenty million years since it was at a temperature in which life on it would have been impossible. Geologists can hardly be blamed if they attach greater weight to their own observations and data and to reasoning that is more familiar and appears more certain and satisfactory to their minds.

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.

In the doxographical tradition the concept of a ‘crystalline’ outer-heaven is ascribed to two Presocratic thinkers. Aëtius tells us that Anaximenes held that the stars were fastened like nails in the ‘crystalline’: (2. 14–3 DK. 13 A14) and, again, that Empedocles believed that the fixed stars were attached to the ‘crystalline’, while the planets were unattached: (2. 13. II DK 31 A54.) The ascription of this concept to both these Presocratic philosophers is decidedly odd; for, whereas, in the case of Empedocles’ thought, fire acts as a solidifying agent, Anaximenes, on the other hand, connected solidity with cold and rarity with heat and in his cosmology the heavenly bodies are created by the rarefaction into fire of vapour from the earth. For this reason the concept of a solid outer-heaven is quite incompatible with the little else that is known of his cosmogony and cosmology.

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 Report on the Geology of the Henry Mountains, Rocky Mountain Region, Mr. G. K. Gilbert, of the U.S. Geographical and Geological Survey, points out that many of the intrusions of eruptive rocks now exposed had a deep-seated origin; the molten rock having filled vacancies in the rocks, and never coming to the surface until they were exposed by denudation or by faults. To quote our author, “The lava … instead of rising through all the beds of the earth's crust, stopped at a lower horizon, insinuated itself between two strata, and opened for itself a chamber by lifting all the superior beds. For these masses of eruptive rocks, Gilbert proposes the name laccolite (Gr. lakkos cistern, and lithos stone). In the Cos. Wexford and Wioklow some of the protrusions of eruptive rocks are entitled to this name, the rocks having congealed in cisterns below the surface of the earth; there are, however, some marked differences between them and the laccolites of the Henry Mountains. The latter were intruded into nearly horizontal strata, the laccolites only consist of one kind of rock, while the adjoining rocks seem to have been very little altered. But the Wexford and Wicklow laccolites, on the other hand, were intruded into highly disturbed strata, they are made up of a variety of rocks, and always the aquo-igneous action due to their intrusion—‘ baked ’ or altered, a greater or less thickness of rocks about them.
