Page 486 - All the world's bravery, that delights our eyes, Is but thy several liveries ; Thou the rich dye on them bestow'st, Thy nimble pencil paints this landscape as thou go'st. A crimson garment in the rose thou wear'st ; A crown of studded gold thou bear'st ; The virgin-lilies, in their white, Are clad but with the lawn of almost naked light.
Page 372 - We believe that it is the duty of every scientific student to investigate nature simply for the purpose of elucidating truth, and that if he finds that some of his results appear to be in contradiction to the Written Word, or rather to his own...
Page 318 - ... marvellous variety of attainments and extent of knowledge ; but during his life he hardly held that elevated place among great discoverers which posterity will probably assign him. In 1802, he was constituted foreign secretary of the Royal Society, an office which he held during life ; in 1827 he was elected one of the eight foreign members of the Institute of France; perhaps the greatest honour which men of science usually receive.
Page 73 - At table I had very good discourse with Mr. Ashmole, wherein he did assure me that frogs and many insects do often fall from the sky, ready formed.
Page 346 - The ether is not a fantastic creation of the speculative philosopher; it is as essential to us as the air we breathe.... The study of this all-pervading substance is perhaps the most fascinating and important duty of the physicist.
Page 317 - Then it was found that seventy-five years were added, at a single step, to the period during which the history of the moon's motion could be written. Previously this history was supposed to commence with the observations of Bradley, at Greenwich, about 1750 ; now it was extended back to 1675, and with a less degree of accuracy thirty years farther still.
Page 182 - The Bruce Gold Medal of the Astronomical Society of the Pacific has been awarded to Professor Ernest W.
Page 468 - A feeling as of inspiration seized me: I felt as if I had it now in my power to lift a veil which had never before been lifted; as If a key had been put into my hands which would unlock a door which had been regarded as forever closed to man — the veil and door behind which lay the unknown mystery of the true nature of the heavenly bodies.
Page 346 - When that comes about, our centres of industrial activity may perhaps be transferred to the burning deserts of the Sahara, and the value of land determined by its suitability for the reception of traps to catch sunbeams. " This energy, in the interval between its departure from the sun and its arrival at the earth, must be in the space between them. Thus this space must contain something which, like ordinary matter, can store up energy...
Page 346 - ... mathematical investigation that the mass of a body must be increased by a charge of electricity. This increase, however, is greater for small bodies than for large ones, and even bodies as small as atoms are hopelessly too large to show any appreciable effect ; thus the result seemed entirely academic. After a time corpuscles were discovered, and these are so much smaller than the atom that the increase in mass due to the charge becomes not merely appreciable, but so great that, as the experiments...
