الصفحة 67 - Now Know Ye, that in compliance with the said proviso, I, the said Adolphe Nicole, do hereby declare that the nature of my said Invention, and the manner in which the same is to be performed, are...
الصفحة 61 - Servants, labourers, and workmen of different kinds, make up the far greater part of every great political society. But what improves the circumstances of the greater part can never be regarded as an inconveniency to the whole. No society can surely be flourishing and happy, of which the far greater part of the members are poor and miserable.
الصفحة 273 - ... as if it were sugar. This, however, I have frequently seen ; although, in the inland parts, the poorer class of inhabitants are so very rarely indulged with this precious article, that to say a man eats salt with his victuals is the same as saying he is a rich man. I have myself suffered great inconvenience from the scarcity of this article. The long use of vegetable food creates so painful a longing for salt, that no words can sufficiently describe it.

الصفحة 170 - At the equator we find the natives of the Spice Islands, the clove and nutmeg trees, pepper and mace. Cinnamon bushes clothe the surface of Ceylon; the odoriferous sandal wood, the ebony tree, the teak tree, the banyan, grow in the East Indies.
الصفحة 83 - My invention relates to a mode of manufacturing alum, by which the same may be produced free of iron and alkali, (or nearly so.) And in order to give the best information in my power, I will proceed to describe the process pursued by me. I take potters...
الصفحة 148 - ... it were better for a man to be subject to any vice than to it ; for all other vanities and sins are recovered, but a drunkard will never shake off the delight of beastliness ; for the longer it possesseth a man the more he will delight in it ; and the older he groweth the more he shall be subject to it ; for it dulleth the spirits, and destroyeth the body, as ivy doth the old tree, or as the worm that engendereth in the kernel of the nut.
الصفحة 148 - TAKE especial care that thou delight not in wine ; for there never was any man that came to honour or preferment that loved it; for it transformeth a man into a beast, decayeth health, poisoneth the breath, destroyeth natural heat, brings a man's stomach to an artificial heat, deformeth • the face, rotteth the teeth, and, to conclude, maketh a man contemptible, soon old, and despised of all wise and worthy men; hated in thy servants, in thyself, and companions; for it is a bewitching and infectious...
الصفحة 149 - Whosoever loveth wine, shall not be trusted of any man, for he cannot keep a secret.
