Seite 180 - O'er bog or steep, through strait, rough, dense, or rare, With head, hands, wings, or feet, pursues his way, And swims, or sinks, or wades, or creeps, or flies.
Seite 245 - Anatomy as a compendious, reliable, and, notwithstanding its small dimensions, most comprehensive guide on the subject of which it treats. To praise or to criticise the work of so accomplished a master of his favorite science would be equally out of place. It is enough to say that It realizes, in a remarkable degree, the anticipations which have been formed of it; and that it presents an extraordinary combination of wide, general views, with the clear, accurate, and succinct statement of a prodigious...

Seite 182 - The sun's rays are the ultimate source of almost every motion which takes place on the surface of the earth. By its heat are produced all winds, and those disturbances in the electric equilibrium of the atmosphere which give rise to the phenomena of lightning, and probably also to those of terrestrial magnetism and the aurora.
Seite 137 - In that paper it was demonstrated experimentally, that the mechanical power exerted in turning a magneto-electric machine is converted into the heat evolved by the passage of the currents of induction through its coils; and, on the other hand, that the motive power of the electro-magnetic engine is obtained at the expense of the heat, due to the chemical reaction of the battery by which it is worked.
Seite 137 - On the Calorific Effects of Magneto-Electricity, and on the Mechanical Value of Heat.

Seite 107 - Andrews' curved lines are to be placed with their planes parallel to one another, and separated by intervals proportional to the differences of the temperatures to which the curves severally belong, and with the origins of coordinates of the curves situated in a straight line perpendicular to their planes, and with th<!
