Pàgina 226 - Committee of the House of Commons, appointed to inquire into the Bankrupt Laws ; and i This and the two preceding motions were lost by large majorities.
Pàgina 245 - ... its free delivery ; 15° below zero is easily produced by this apparatus. The bottle, when not in use, should be kept tightly corked, a precaution by no means superfluous, as the liquid readily loses its more volatile parts by evaporation, leaving a denser and consequently less efficient residue. In this, and in several more expensive forms of apparatus in metal, both with...
Pàgina 270 - ... shake the bottle at intervals for half an hour, when the amount of oily residue will show the impurity. Or, dissolve one part of caustic soda in ten parts of warm water, and snake it up with five parts of the carbolic acid. As before, the residue will indicate the amount of impurity.
Pàgina 69 - Oleander." The author confirms the observations of Orfila as to the effects of an alcoholic-aqueous extract of the leaves of the common oleander. He finds that it paralyses the heart, and suggests that the leaves might be employed in medicine in the same cases and with the same precautions as digitalis. NOTICES OP BOOKS. Report on Water for Locomotives and Boiler Incrustations, made to the President and Directors e>f the fi'ew York Central Railroad.
Pàgina 54 - ... indorsements, like merchants who have lent their name to paper enough to sweep their whole property ; and now we are like those same merchants when at last their paper is all gathered up, and their name is cancelled, and there is not the scratch of a pen against them. There is one feature in the Proclamation to which I desire to call your attention, and that is the declaration of the...
Pàgina 245 - Richardson not being absolutely necessary to congeal the tissues with the rhigolene, as in his experiments with common ether. I have for convenience used a glass phial, through the cork of which passes a metal tube for the fluid, the air-tube being outside, and bent at its extremity so as to meet the fluid-tube at right angles, at some distance from the neck of the bottle. Air is not admitted to the bottle as in Dr.
Pàgina 198 - The acid extracts were mixed and filtered after cooling, neutralised with caustic soda, and repeatedly shaken up with their own bulk of ether. The residue left after evaporation of the ether was taken up by dilute sulphuric acid, filtered and tested for fluorescence. The pig that had taken no quinine had each organ treated in a precisely similar way. To our great disappointment, at first we found that not only had the pig that had taken quinine...
Pàgina 258 - As frequent mention is made of the different sized machines employed in these investigations, they are distinguished by the calibre or bore of the magnet-cylinders. Each cylinder was fitted with an armature, round which was coiled an insulated strand of copper wire 67 feet in length, and 0*15 of an inch in diameter. Upon one of the magnet-cylinders...
Pàgina 258 - The armatures of the 2^-inch magnetoelectric and electro-magnetic machines were driven simultaneously at an equal velocity of 2500 revolutions per minute. When the electricity from the magneto-electric machine was transmitted through a piece of No. 20 iron wire 0-04 of an inch in diameter, a length of 3 inches of this wire was made red-hot. When the direct current from the magneto-electric machine was transmitted through the coils of the electro-magnet of the electromagnetic machine, the electricity...
