Страница 114 - ... further how large a quantity of heat might be produced by proper mechanical contrivance, merely by the strength of a horse, without either fire, light, combustion, or chemical decomposition; and, in a case of necessity, the heat thus produced might be used in cooking victuals.
Страница 417 - At first they could not be persuaded of the reality of the appearance ; but they soon became so thoroughly convinced, by the cliffs gradually appearing more elevated, and approaching nearer, as it were, that they pointed out, and named to me, the different places they had been accustomed to visit ; such as the Bay, the Old Head or Man, the Windmill, &c. at Boulogne ; St. Vallery, and other places on the coast of Picardy ; which they afterwards confirmed, when they viewed them through their telescopes.
Страница 138 - Paulus ./Egineta fpeaks of fugar, as growing, in his time, in Europe, and alfo as brought from Arabia Felix ; the latter of which he feems to think lefs fweet than the fugar produced in Europe, and neither injurious to the Ûomach nor caufing thirft, as the European fugar was apt to do.
