Página 169 - ... them; and that these primitive particles being solids, are incomparably harder than any porous bodies compounded of them; even so very hard, as never to wear or break in pieces: no ordinary power being ' able to divide what God himself made One, in the first creation.
Página 27 - This rule is based upon the fact, that a solid when weighed in water loses weight equal to the water it displaces ; and the bulk of the water displaced is exactly equal to its own. Suppose a piece of gold weighs in...
Página 149 - ... the electricity which decomposes, and that which is evolved by the decomposition of, a certain quantity of matter, are alike.
Página 95 - ... atmosphere. The tendency of this pressure is to prevent and retard the particles of water from expanding to a sufficient extent to form steam. Hence, if the pressure of the atmosphere varies, as it does at different times and places, or if it be increased or diminished by artificial means, the boihng point of a liquid will undergo a corresponding change.
Página 119 - ... it is exceeded by a few deeply-colored, almost Opaque minerals. It is in part from this property that the diamond owes its brilliancy as a jewel. Many years before the combustibility of the diamond was proved by experiment, Sir Isaac Newton predicted, from the circumstance of its high refractive power, that it would ultimately be found to be inflammable. The determination of the refracting power of a body is often a valuable guide in estimating its chemical purity. The adulteration of essential...

Página 79 - From its extreme softness, its particles slide over each other in the act of expansion, and do not return to their original position. " A leaden pipe, used for conveying steam, permanently lengthens some inches in a short time, and the leaden flooring of a sink, which often receives hot water, becomes, in the course of use, thrown up into ridges and puckers.
Página 26 - The specific gravity, or specific weight of a body, is its weight as compared with the weight of an equal bulk of some other substance, assumed as the standard of comparison.
Página 406 - Creosote diluted with alcohol is often employed for relieving toothache arising from putrefactive decay in the substance of the tooth, and as a styptic for checking hemorrhage. When taken internally in any quantity it is a corrosive poison, but a very dilute solution is sometimes given in medicine. It is also extensively employed by liquor manufacturers for imparting the peculiar smoky flavor to what is called
Página 151 - No elementary substance can be an electrolyte : for from the nature of the process, compounds alone are susceptible of electrolysis. 2. Electrolysis occurs only whilst the body is in the liquid state. The free mobility of the particles which form the body undergoing decomposition is a necessary condition of electrolysis, since the operation is always attended by a transfer of the component particles of the electrolyte in opposite directions. Electrolysis is necessarily a process of electrical conduction,...
