Page 146 - They are taught to repeat a great number of verses by heart, and often spend twenty years upon this institution ; for it is deemed unlawful to commit their statutes to writing; though in other matters, whether public or private, they make use of Greek characters. They seem to me to follow this method for two reasons: to hide their mysteries from the knowledge of the vulgar; and to exercise the memory of their scholars...
Page 135 - In the general intercourse of society, Dr Henry was distinguished by a polished courtesy, by an intuitive propriety, and by a considerate forethought and respect for the feelings and opinions of others ; — qualities issuing out of the same highlytoned sensibility, that guided in taste his letters, and that softened and elevated his whole moral frame and bearing.
Page 145 - Id mihi duabus de causis instituisse videntur, quod neque in vulgum disciplinam efferri velint neque eos, qui discunt, litteris confisos minus memoriae studere : quod fere plerisque accidit, ut praesidio litterarum diligentiam in perdiscendo ac memoriam remittant.
Page 477 - ... her little, fevered hands gently rest on each other, near to her head. The plain, and only drapery is a frock, the skirt flowing easily out before, and a ribbon sash, the knot twisted forward, as it were, by the restlessness of pain, and the two ends spread out in the same direction with the frock. The delicate, naked feet are carelessly folded over each other : and the whole appearance is as if she had just turned, in the tossings of her illness, to seek a cooler or an easier place of rest.
Page 173 - ... little friction. White cast iron, in a recent fracture, has a white and radiated appearance, indicating a crystalline structure. It is very brittle and hard. Gray cast iron has a granulated fracture, of a gray colour, with some metallic lustre ; it is much softer and tougher than the white cast iron. But between these kinds there are varieties of cast iron...
Page 120 - The property inherent in certain gases, of retarding the action of the platinum sponge, when they are added to an explosive mixture of oxygen and hydrogen, is most remarkable in those which possess the strongest attraction for oxygen ; and it is probably to the degree of this attraction rather than to any agency arising out of their relations to caloric, that we are to ascribe the various powers which the gases manifest in this respect.
Page 144 - It was wrote in Greek characters, that if it fell into the enemy's hands, it might not be intelligible to them. The messenger had orders, in case he found it impracticable to penetrate himself into the Roman camp, to tic the letter to a javelin, and throw it in.
Page 465 - I. The first class is that which resolves the emotion of taste directly into an original law of our nature ; which supposes a sense, or senses, by which the qualities of beauty and sublimity are perceived and felt, as their appropriate objects ; and concludes, therefore, that the genuine object of the arts of taste, is to discover, and to imitate, those qualities in every subject, which the prescription of nature has thus made essentially either beautiful or sublime. To this first class...
Page 114 - ... Henry described in the Philosophical Transactions for 1808, a form of apparatus, adapted to the combustion of larger quantities of gas than could be fired in eudiometric tubes. Resuits were thus obtained, which may be pronounced fair approximations to truth, especially when estimated with reference to the still imperfect resources of pneumatic chemistry. The apparatus cannot, however, be now recommended when extreme precision is desirable. In this year (1808) he was elected a Fellow of the Royal...
Page 114 - ... the same volume of condensed gas as of gas under ordinary pressure. 'But, as the spaces occupied by every gas are inversely as the compressing force, it follows, that water takes up, of gas condensed by one, two, or more additional atmospheres, a quantity which, ordinarily compressed, would be equal to twice, thrice, &c. the volume absorbed under the common pressure of the atmosphere.
