Includes fog-signals, fireworks, fuzes, rockets, percussion caps, detonators, cartridges, ammunition of all descriptions, and every adaptation or preparation of an explosive as above defined.
Page 346 - As a unit of resistance, the international ohm, which is based upon the ohm equal to 109 units of resistance of the CGS system of electro-magnetic units, and is represented by the resistance offered to an unvarying electric current by a column of mercury at the temperature of melting ice 14-4521 grammes in mass, of a constant cross-sectional area and of the length of 106-3 cm.
Page 674 - The two preceding sections shall not be so construed as to prevent any State, Territory, district, city, or town within the United States from regulating or from prohibiting the traffic in or transportation of those substances, between persons or places lying or being within their respective territorial limits, or from prohibiting the introduction thereof into such limits, for sale, use, or consumption therein.
Page 346 - As a unit of quantity, the international coulomb, which is the quantity of electricity transferred by a current of one international ampere in one second. As a unit of capacity, the international farad, which is the capacity of a condenser charged to a potential of one international volt by one international coulomb of electricity.
Page 346 - The unit of current shall be what is known as the international ampere, which is one-tenth of the unit of current of the centimeter gram-second system of electro-magnetic units, and is the practical equivalent of. the unvarying current, which, when passed through a solution of nitrate of silver in water in accordance with standard specifications, deposits silver at the rate of one thousand one hundred and eighteen millionths of a gram per second.
Page 678 - nitro-compound " means any chemical compound possessed of explosive properties, or capable of combining with metals to form an explosive compound, which is produced by the chemical action of nitric acid (whether mixed or not with sulphuric acid) or of a nitrate mixed with sulphuric acid upon any carbonaceous substance, whether such compound is mechanically mixed with other substances or not.
Page 91 - The work is naturally divided into three sections: — 1. The systematic investigation of the waters of the United States and the biological and physical problems which they present.
