Improvements in the arts and sciences (väriä koskevat kohdat)

Scientific American 1, 2.1.1864

There exists in England a Society for the encouragement of the Arts and Sciences, which numbers among he members many of the best and most talented persons in the United Kingdom. Prince Albert, when living, took an active part in the proceedings of this institution and aided its objects by every means in his power. Whether it was the comfort of the working-classes which engrossed his mind, or whether the perfection of some rare and beautiful work of art, in tended to give pleasure to more cultivated intellects, his energies, time and money, were equally interested and devoted to the fullest accomplishment of the duty in hand.

In pursuance of its object to encourage the arts and render Great Britain first in all that pertains to civilization, the Society offered premiums varying in ammount from $500 to $100 for the best inventions or discoveries to the arts and sciences. They also publish lists of certain substances, articles, fabrics, instruments, machines, colors, processes, &c., &c., in daily use, which are to be the subjects of special premiums. For some improvements medals are offered, which it is supposed bear a high value; not so much, perhaps, for their intrinsic worth as for the honor conferred by them upon the recipient. We transfer to our columns a number of the subjects for which prices are offered, not with the idea of inducing competition among our countrymen for the possession of the premiums, as that is not permitted, we believe, by the Society; but mainly with the object of placing before our readers, in pursuance of the design of the Scientific American, the latest and most pressing wants of the age we live in:
