Pagina 450 - And ever against eating cares Lap me in soft Lydian airs Married to immortal verse, Such as the meeting soul may pierce In notes, with many a winding bout Of linked sweetness long drawn out, With wanton heed and giddy cunning, The melting voice through mazes running, Untwisting all the chains that tie The hidden soul of harmony; That Orpheus...
Pagina 452 - For there is a music wherever there is a harmony, order, or proportion; and thus far we may maintain the music of the spheres ; for those well-ordered motions, and regular paces, though they give no sound unto the ear, yet to the understanding they strike a note most full of harmony.
Pagina 15 - I have lately been prosecuting this inquiry with remarkable success. The principle cannot be entered upon in this paper, but I shall just subjoin the results, as far as they appear to be ascertained by my experiments." TABLE OF THE RELATIVE WEIGHTS OF THE ULTIMATE PARTICLES OF GASEOUS AND OTHER BODIES.
Pagina 2 - I have succeeded better than many who surround me, in the different walks of life, it has been chiefly, nay, I may say almost solely, from unwearied assiduity. It is not so much from any superior genius that one man possesses over another, but more from attention to study and perseverance in the objects before them, that some men rise to greater eminence than others.
Pagina 14 - I am nearly persuaded that the circumstance depends upon the weight and number of the ultimate particles of the several gases : those whose particles are lightest and single being least absorbable, and the others more according as they increase in weight and complexity...
Pagina 15 - An enquiry into the relative weights of the ultimate particles of bodies is a subject, as far as I know, entirely new : I have lately been prosecuting this enquiry with remarkable success. The principle cannot be entered upon in this paper ; but I shall just subjoin the results, as far as they appear to be ascertained by my experiments.
Pagina 376 - It was, however, an obstruction of such a character as to leave no doubt upon my mind as to our future proceedings, for we might with equal chance of success try to sail through the cliffs of Dover, as penetrate such a mass.
Pagina 457 - ... elastic, its effects must strongly resemble those of sound, since every sounding body is in a state of vibration, and the air, or any other medium, which transmits sound, conveys its undulation to distant parts by means of its elasticity. And we shall find that the principal phenomena of heat may actually be illustrated by a comparison with those of sound. The excitation of heat and sound are not only similar, but often identical ; as in the operations of friction and percussion : they are both...
Pagina 168 - ... that the natural knowledge which has been given to the world in such abundance during the last fifty years should remain, I may say, untouched, and that no sufficient attempt should be made' to convey it to the young mind, growing up and obtaining its first views of these things, is to me a matter so strange that I find it difficult to understand it.
Pagina 12 - There can scarcely be a doubt entertained respecting the reducibility of all elastic fluids of whatever kind into liquids; and -we ought not to despair of effecting it in low temperatures, and by strong pressure exerted upon the unmixed gases.
