Page 206 - Glasgow, mechanic, for an invention of " a machine for preparing wood for joiners, carpenters, and others."— 2d Oct. 1838. 7. To EDMOND HENZE of Fenton's Hotel, James' Street, in the county of Middlesex, merchant, in consequence of a communication made to him by a certain foreigner residing abroad, for an invention of " improvements in the manufacture of dextrine.
Page 422 - London, stationer, in consequence of a communication made to him by. a certain foreigner residing abroad, for an invention of improvements in the manufacture of paper and paper-boards.
Page 352 - Pyrenees, 1815, p. 435, 459. thermal springs nearer the principal granitic mass are warmer, while those more remote are colder. Professor Forbes has likewise pointed out, in an interesting memoir on the temperatures and geological relations of certain hot springs, particularly those of the Pyrenees...
Page 54 - ... appear at the surface till they have heated the water to their own temperature. When so much vapor has escaped that the expansive force of that which remains has become less than the pressure of the confining column of water, tranquillity is restored, and this lasts until such a quantity of vapor is again collected as to produce a fresh eruption. The spouting of the spring is, therefore, repeated at intervals, depending upon the capacity of the cavern, the height of the column of water, and the...
Page 393 - They may be made tighter than the ordinary kind, yet no unequal pressure is felt : indeed, support is given to the foot, and this is particularly beneficial when there is any weakness of the parts. They are rendered light by the absence of that weight of rigid leather placed in the sole immediately under the arch of the foot. short, the natural exercise of the parts, whether they be active or passive, is the stimulus to the circulation through them, exercise being as necessary to the perfect constitution...
Page 374 - ... in the first sketch; but there was also an oscillating motion of the great chains across the work, though the one seemed to destroy the other, as they did not both (at least as far as could be seen) take place in a marked manner at the same time. At last the railing on the east side was seen to be breaking away, falling into the sea; and immediately the undulations increased; and when the railing on this side was nearly all gone, the undulations were quite as great as represented in the drawing.
Page 373 - I, is a sketch shewing th,e appearance of the third span after it gave way. " The same span of the Brighton chain-pier (the third from the shore), has now twice given way in a storm. The first time it happened in a. dark night, and the storm was accompanied by much thunder and lightning : the general opinion of those who do not inquire into the causes of such matters was, that it was destroyed by lightning ; but the persons employed about the pier, and whose business it was to repair it, were satisfied...
Page 53 - ... light as intermittent springs, with this difference only, that instead of water, they throw out melted matters. " He takes it for granted that these hot springs derive their temperature from aqueous vapors rising from below. When these vapors are able to rise freely in a continual column, the water at the different depths must have a constant temperature, equal to that at which water would boil under the pressure existing at the respective depths ; hence the constant ebullition of the permanent...
Page 338 - Cumana 1797, presented an instance of the same factThe predominant direction of the frequent earthquakes on the coasts of Chili and Peru, is also that of the large chain of the Andes, which is parallel to the coast. § All the older reports likewise state, that in these countries their direction is from S. to N., or vice versa ; and Mrs Graham remarked, that she felt, during the violent earthquake in Chili 1822, as if the whole ground from north to south were suddenly raised, and then sunk again....
Page 404 - November 1836, when the velocity of the wind was estimated at about 100 feet per second, the sea at Plymouth was raised three feet six and a half inches above the mean level, the greatest height above the equilibrium level he has seen. The hurricane began at SW, and the barometer was very low ; therefore this great increase in height is due both to the wind and diminished atmospheric pressure. A gale of wind from the southward, a low barometer, and a high spring-tide concurring, cause damage and...
