Page 386 - Nature never did betray The heart that loved her ; 'tis her privilege Through all the years of this our life, to lead From joy to joy : for she can so inform The mind that is within us, so impress With quietness and beauty, and so feed With lofty thoughts, that neither evil tongues, Rash judgments, nor the sneers of selfish men, Nor greetings where no kindness is, nor...
Page 329 - ... and in what direction, and how far, improvement is possible; and since the increase in our knowledge of the properties of matter enables us to form an opinion beforehand as to the substances we have available for obtaining a desired result, we can now foresee, in most cases, in what direction progress in technology will move, and in consequence the inventor is now frequently in advance of the wants of his time. He may even create new wants, to my mind a distinct step in the development of human...
Page 366 - To change is always seeming fickleness. But not to change with the advance of science is worse; it is persistence in error.
Page 293 - England will, beyond question, at no distant day become herself the greatest colourproducing country in the world ; nay, by the strangest of revolutions, she may ere long send her coal-derived blues to indigo-growing India, her tar-distilled crimson to cochineal-producing Mexico, and her fossil substitutes for quercitron and safflower to China, Japan, and the other countries whence these articles are now derived.

Page 350 - Athenseum, in conformity with the principles on which it was originally founded, that the annual introduction of a certain number of persons of distinguished eminence in science, literature or the arts or for public services should be secured, a limited number of persons of such qualifications shall be elected by the Committee.

To our surprise we found that, while the apparatus was cooling down, the flame of the escaping gas became luminous and increased in luminosity as the temperature got below 100° C. On a cold plate of porcelain...
