Not illustrated. 1802 Excerpt: ...it is said, that gold is 19 times heavier than water, we mean, that having two equal masses, the one of gold, the other of water, that which is of gold will have 19 times the weight of that which is of water. When we thus express ourselves, we fay nothing of the absolute weight of bodies, we only speak by way of comparison, and with a reference always to masses of an equal size. Neither is it of importance, whether the size be great or small, provided they be equal. 35/A Aug, 1760. LETTER XLVII. Terms relative to Gravity, and their true Import. f? RAVITY, or weight, seems, so essential to the-nature of bodies, that it is almost impossible to form the idea of a body divested of this quality. And it's influence is so universal, in all our operations upon body, that we must, in every instance, pay attention to it's gravity, or weight. As to our own persons, whether we stand, sit, or lie, we continually feel the effect of the gravity of our own body; we could never fall, if the body were not, as well as all it's parts, endowed with this force. Language itself is regulated according to this property of bodies. The place toward which a body tends ia it's descent, we term low; and the opposite direction from the body, we term high. It must be remarked, that when a body, in falling, is at perfect liberty, it always descends in a straight line, pursuing which, it's direction is said to be downward. This line is likewise called vertical, by which term we always mean a straight line, drawn from high to low; and if we conceive this line produced upward, till it reaches heaven, we call that point in the heavens our zenith, an Arabian word, denoting that point in the heavens which is directly over our head. You comprehend, then, that a vertical line, is that straight lin...

Not illustrated. 1833 edition. Excerpt: ... in order to grant an uninterrupted transmission to the magnetic matter. Iron and steel, Ihen, apparently contain such particles in great abundance; these are not, however, originally disposed in the manner I have been describing, but are scattered over the whole mass, and this disposition is all they want to become real magnets. In that case, they still retain all their other qualities, and are not distinguishable from other masses of iron and steel, except that now they have besides the properties of the loadstone; a knife and a needle answer the same purposes, whether thejr have or want the magnetic virtue. The change which lakes place in the interior, from the arrangement of the particles in the order which magnetism requires, is not externally perceptible; and the iron or steel which has acquired the magnetic force is denominated an artificial magnet, to distinguish it from the natural, which resembles a stone, though the magnetic properties are the same in both. Yon will have a curiosity, no doubt, to be informed in what manner iron and steel may be brought to receive the magnetic force, and so become artificial magnets. Nothing can be more simple; and the vicinity of a loadstone is capable of rendering iron somewhat magnetic: it is the magnetic vortex which produces this effect, even though the iron and loadstone should not come into contact. However hard iron may appear, the particles which contain the magnetic pores formerly represented are very pliant in substance, and the smallest force is sufficient to change their situation. The magnetic matter of the vortex, entering into the iron, will then easily dispose the first magnetic pores which it meets following its own directions--those at least whose situation is not very...
