**deformation**by various theories of magnetic stress,' notably that elaborated by G. - Thomson, who, from the results of Bidwell's observations on the magnetic
**deformation**of cobalt, was led to expect that that metal would exhibit a reversal opposite in character to the effect observed in iron. - In this category may be placed head-
**deformation**, which reached its extreme development among the Indians of North-West America and the ancient Peruvians; foot-constriction as practised by the Chinese; tooth-chipping among many African tribes; and waist-compression common in Europe at the present day. - Many forms of
**deformation**, it may be remarked in passing, emphasize some natural physical characteristic of the people who practise them. - Strains exceeding the "limit of elasticity" result in permanent
**deformation**or (if sufficiently great) in rupture. - " It has long been known that proglottides of the same species often exhibit sporadic malformation from the normal shape, and the evidence goes to show that the variation was due to arrested growth or some unusual stress or pressure which, acting upon the young strobila, produced a
**deformation**, and that the proglottides so affected could not regain their normal form. - The essential part of many transmission dynamometers is a spring whose
**deformation**indirectly measures the magnitude of the force transmitted through it. - The accidental use of a single name, America, for the pair of continents that has a greater extension from north to south than any other continuous land area of the globe, has had some recent justification, since the small body of geological opinion has turned in favour of the theory of the tetrahedral
**deformation**of the earth's crust as affording explanation of the grouping of continents and oceans. - The chains of each pair were connected by bracing so that they formed a stiff inverted arch resisting
**deformation**in its place. - Impact.-If a vertical load is imposed suddenly, but without velocity, work is done during deflection, and the
**deformation**and stress are momentarily double those due to the same load at rest on the structure. - The action of pressure is shown also by the fossils which sometimes occur in slates; they have been drawn out and distorted in such a way as to prove that the rock has undergone
**deformation**and has behaved like a plastic mass. - Trend to crustal
which in very early geological time gave a beginning to what later came to be the Appalachian mountain system; but this system had Its climax of**deformations****deformation**so long ago (probably in Permian time) that it has since then been very generally reduced to moderate or low relief, and owes its present altitude either to renewed elevations along the earlier lines or to the survival of the most resistant rocks as residual mountains. - The
**deformation**of the Appalachianswas accomplished in two chief periods of compressive**deformation**, one in early Palaeozoic, the other about the close of Palaeozoic time, and both undoubtedly of long duration; the second one extended its effects farther northwest than the first. - Evi-Jently, therefore, the Appalachians as we now see them are not the still surviving remnants of the mountains of late Palaeozoic
**deformation**; they owe their present height chiefly to the Tertiary upwaroing and uoliftinr. - The extent of the submergence and the area over which the Palaeozoic strata were deposited are unknown; for in consequence of renewed elevation without
**deformation**, erosion in later periods has stripped off an undetermined amount of the covering strata. - The structure of the region previous to faulting was dependent on long antecedent processes of accumulation and
**deformation**and the surface of the region then was dependent on the amount of erosion suffered in the prefaulting cycle. - Triassic SystemThis system has but limited representation in the eastern part of the United States, being known only east of the Appalachian Mountains in an area which was land throughout most of the Palaeozoic era, hut which was deformed when the eastern mountains were developed at the close of the Palaeozoic. In the troughs formed in its surface during this time of
**deformation**, sediments of great thickness accumulated during the Triassic period. - Its deposition seems to have followed a time of
**deformation**which resulted in an increase of altitude in the Appalachian Mountains, and in an accentuation of the contrast between the highlands and the adjacent plains. - This epoch of great
**deformation**and warping marks the transition from the Tertiary to the Quaternary. - It must be incapable of
**deformation**without alteration of length in at least one of its bars. - In any infinitely small
**deformation**of the frame as thus modified, the virtual work of the forces 5, together with that of the original extraneous forces, must ~ranish this determines S. - Imagine the bar CF to be removed, and consider a
**deformation**in which AB is fixed. - 52, if an infinitesimal
**deformation**is possible without removing the bar CF, the instantaneous centre of CF (when AB is fixed) will be at the intersection of AF and BC, and since CC, FF represent the virtual velocities of the points C, F, turned each through a right angle, CF must be parallel to CF. - Conversely, if this condition be satisfied, an infinitesimal
**deformation**is possible. - Under this head fall the following: - Fasting, or abstention from certain meats and drinks; denial of sexual instinct; subjection of the body to physical discomforts, such as nakedness, vigils, sleeping on the bare ground, tattooing,
**deformation**of skull, teeth, feet, &c., vows of silence to be observed throughout life or during pilgrimages, avoidance of baths, of hair-cutting and of clean raiment, living in a cave; actual self-infliction of pain, by scourging, branding, cutting with knives, wearing of hair shirts, fire-walking, burial alive, hanging up of oneself by hooks plunged into the skin, suspension of weights by such hooks to the tenderer parts of the body, self-mutilation and numerous other, often ingenious, modes of torture. - The heights of peaks determined by exact processes of trigonometrical observation are bound to be more or less in error for three reasons: (1) the extraordinary geoidal
**deformation**of the level surface at the observing stations in submontane regions; (2) ignorance of the laws of refraction when rays traverse rarefied air in snow-covered regions; (3) ignorance of the variations in the actual height of peaks due to the increase, or decrease, of snow. - Whatever the
**deformation**of the originally straight boundary of the axial section may be, it can be resolved by Fourier's theorem intoof the harmonic type.**deformations** - It must not only be strong enough to sustain all possible vertical loads, but it must be sufficiently rigid to resist without
**deformation**or weakening all lateral disturbing forces, the principal of which are the pressure of wind, the possible sway of moving crowds or moving machinery, and the vibration of the earth from the passage of loaded vans and trolleys, and slight earthquakes which at times visit almost all localities.
