Page 139 - Upon inquiring what kind of animal it was, to our astonishment, the person who brought me the manuscript described exactly the unicorn of the ancients : saying, that it was a native of the interior of Thibet, about the size of a tattoo, (a horse from twelve to thirteen hands high,) fierce and extremely wild ; seldom, if ever, caught alive, but frequently shot; and that the flesh was used for food.
Page 98 - I am further inclined to think, that when our views *' ' are sufficiently extended, to enable us to reason with precision concerning the proportions of elementary atoms, we shall find the arithmetical relation alone will not be sufficient to explain their mutual action, and that we shall be obliged to acquire a geometrical conception of their relative arrangement : in all the three dimensions of solid extension.
Page 203 - I gave it the name of the drawing-room ; for it is covered with figures, which, though only outlined, are so fine and perfect, that you would think they had been drawn only the day before.
Page 296 - A Practical Treatise on the Inflammatory, Organic, and Sympathetic Diseases of the Heart ; also on Malformations of the Heart, Aneurism of the Aorta, Pulsation in Epigastrio, &c.
Page 205 - I cannot give an adequate idea of this beautiful and invaluable piece of antiquity, and can only say, that nothing has been brought into Europe from Egypt that can be compared with it. The cover was not there : it had been taken out, and broken into several pieces, which we found in digging before the first entrance. The sarcophagus was over a staircase in the centre of the saloon, which communicated with a subterraneous passage, leading downwards, three hundred feet in length. At the end of this...
Page 206 - Where a figure or any thing else was required to be formed, after the wall was prepared, the sculptor appears to have made his first sketches of what was intended to be cut out. When the sketches were finished in red lines by the first artist, another more skilful corrected the errors, if any, and his lines were made in black, to be distinguished from those which were imperfect. When the figures were thus prepared, the sculptor proceeded to cut out the stone all round the figure, which remained in...
Page 376 - Since the time we first entered Sir James Lancaster's Sound, the sluggishness of the compasses, as well as the amount of their irregularity produced by the attraction of the ship's iron, had been found very rapidly, though uniformly, to increase as we proceeded to the westward ; so much, indeed, that for the last two days...
Page 382 - ... the landscape of a cultivated country ; it was the death-like stillness of the most dreary desolation, and the total absence of animated existence. Such, indeed, was the want of objects to afford relief to the eye or amusement to the mind, that a stone of more than usual size appearing above the snow in the direction in which we were going, immediately became a mark, on which our eyes were unconsciously fixed, and towards which we mechanically advanced.
Page 376 - It is more easy to imagine than describe the almost breathless anxiety which was now visible in every countenance, while, as the breeze increased to a fresh gale, we ran quickly up the sound. The mast-heads were crowded by the officers and men during the whole afternoon ; and an unconcerned observer, if any could have been unconcerned on such an occasion, would have been amused by the eagerness with which the various reports from the crow's nest were received ; all, however, hitherto favourable to...

The staircase of the entrance-hall had been walled up also at the bottom, and the space filled with rubbish, and the floor covered with large blocks of stone, so as to deceive any one who should force the fallen wall near the pit, and make him suppose, that the tomb ended with the entrance-hall and the drawing-room.
