Seite 230 - Some cause there must be, which would explain how the practice has become a necessary of life to whole nations. But it is surely still more remarkable, that the beneficial effects of both plants on the health must be ascribed to one and the same substance, the presence of which in two vegetables, belonging to different natural families, and the produce of different quarters of the globe, could hardly have presented itself to the boldest imagination.
Seite 669 - We believe that the importation of one hundredweight of guano is equivalent to the importation of eight hundred-weight of wheat — the hundred-weight of guano assumes in a time which can be accurately estimated the form of a quantity of food corresponding to eight hundred- weight of wheat. The same estimate is applicable in the valuation of bones.

Seite 667 - ... excellent remuneration. The origin and formation of sulphuric acid was studied most carefully ; and from year to year, better, simpler, and cheaper methods for making it were discovered. With every improvement in the mode of manufacture, its price fell ; and its sale increased in an equal ratio. Sulphuric acid is now manufactured in leaden chambers, of such magnitude that they would contain the whole of an ordinary-sized house. As regards the process and the apparatus, this manufacture has reached...
Seite 254 - The mixture was placed in a watch-glass, and spread out so as to expose a large surface to the air; the watch-glass was placed on a support in a copper vessel (the air contained in this vessel could be brought to any required temperature). The experiment being thus disposed, the vessel was heated, and by the time that the air in the interior arrived at 248° Fah. a change began to take place in the mixture, and at 266° Fah.
Seite 669 - MY recent researches into the constituent ingredients of our cultivated fields have led me to the conclusion that, of all the elements furnished to plants by the soil and ministering to their nourishment, the phosphate of lime — or, rather, the phosphates generally — must be regarded as the most important.
Seite 669 - ... plants which contain the least amount of the phosphates, and therefore require the smallest quantity for their development. These roots contain 80° to 92° per cent, of water. Their great bulk makes the amount of produce fallacious, as respects their adaptation to the food of animals, inasmuch as their contents of the ingredients of the blood...
Seite 230 - We shall never certainly be able to discover how men were led to the use of the hot infusion of the leaves of a certain shrub (tea), or of a decoction of certain roasted seeds (coffee). Some cause there must be which would explain how the practice has become a necessary of life to whole nations.
