Page 4 - Ibs. of carbon ; a quantity which amounts to more than the weight of all the plants, and of all the strata of mineral and brown coal, which exist upon the earth. This carbon is, therefore, more than adequate to all the purposes for which it is required.
Page 241 - ... 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...
Page 266 - ... 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.
Page 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.

There is one feature in the Proclamation to which I desire to call your attention, and that is the declaration of the...
Page 241 - 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.
Page 194 - 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...
Page 254 - 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...
Page 254 - 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...
