Σελίδα ii - District Clerk's Office. BE IT REMEMBERED, That on the seventh day of May, AD 1828, in the fifty-second year of the Independence of the UNITED STATES OF AMERICA, SG Goodrich, of the said District, has deposited in this office the...
Σελίδα 231 - Salts formed by the combination of any base with the acid of borax. c. Calcareous. A chemical term formerly applied to describe chalk, marble , and all other combinations of lime with carbonic acid.
Σελίδα 233 - Salts formed by the combination of any base with fluoric acid. Fluidity. A term applied to all liquid substances. Solids are converted to fluids by combining with a certain portion of caloric. Flux. A substance...
Σελίδα 232 - D. Decomposition. The separation of the constituent principles of compound bodies by chemical means. Deflagration. The vivid combustion that is produced whenever nitre, mixed with an inflammable substance, is exposed to a red heat. It may be attributed to the extrication of oxygen from the nitre, and its being transferred to the inflammable body ; as any of the nitiates or oxygenized muriates will produce the same effect.
Σελίδα 234 - The Smallest weight made use of by chemical writers. Twenty grains make a scruple ; 3 scruples a drachm ; 8 drachms, or 480 grains, make an ounce ; 12 ounces, or 5760 grains, a pound troy. The avoirdupois pound contains 7000 grains. Granulation. The operation of pouring a melted metal into water, in order to divide it into small particles for chemical purposes. Tin is thus granulated by the dyers before it is dissolved in the proper acid. Gravity, specific.
Σελίδα 99 - Hence ink stains degenerate into iron-moulds, and these last are immediately produced on an inked spot of linen when washed with soap, because the alkali of the soap abstracts the gallic acid, and leaves only an oxide of iron.
Σελίδα 30 - In air, similar currents are continually produced, and the vibratory motion observed over chimney pots, and slated roofs which have been heated by the sun, depends upon this circumstance: the warm air rises, and its refracting power being less than that of the circumambient...
Σελίδα 202 - When pieces of charcoal about an inch long and one-sixth of an inch in diameter were brought near each other (within the thirtieth or fortieth of an inch), a bright spark was produced, and more than half the volume of the charcoal became ignited to whiteness; and, by withdrawing the points from each other, a constant discharge took place through the heated air, in a space equal to at least four inches, producing a most brilliant ascending arch of light, broad and conical in form in the middle.
Σελίδα 233 - ... escape of a gaseous substance. Efflorescence. A term commonly applied to those saline crystals which become pulverulent on exposure to the air, in consequence of the loss of a part of the water of crystallization. Elasticity. A force in bodies, by which they endeavour to restore themselves to the posture from whence they were displaced by an external force. Elastic fluids. A name sometimes given to vapours and gases. Vapour is called an clastic fluid ; gas, a permanently elastic fluid.
Σελίδα 233 - Ethers. Volatile liquids formed by the distillation of some of the acids with alcohol. Evaporation. The conversion of fluids into vapor by heat. This appears to be nothing more than a gradual solution of the aqueous particles in atmospheric air, owing to the chemical attraction of The latter for water. Eudiometer. An instrument invented by Dr, Priestley for determining the purity of any given portion of atmospheric air.
