Sivu 177 - It was a beautifully clear evening, and we had a most enchanting view of the two magnificent ranges of mountains, whose lofty peaks, perfectly covered with eternal snow, rose to elevations varying from seven to ten thousand feet above the level of the ocean.
Sivu 210 - As we approached the land under all studding sails, we perceived a low white line extending from its eastern extreme point as far as the eye could discern to the eastward. It presented an extraordinary appearance, gradually increasing in height as we got nearer to it, and proving at length to be a perpendicular cliff of ice between 150 and 200 feet above the level of the sea, perfectly flat and level at the top, and without any fissures or promontories on its even seaward face...
Sivu xi - With reference to the second branch, viz. the secular and periodical variations, it is observed that — "The progressive and periodical being mixed up with the transitory changes, it is impossible to separate them so as to obtain a correct knowledge and analysis of the former, without taking express account of and eliminating the latter...
Sivu xxii - ... Majesty's pleasure that an attempt should be made to find out a northern passage by sea from the Pacific to the Atlantic Ocean ; and whereas, we have in pursuance thereof, caused His Majesty's sloops Resolution and Discovery to be fitted, in all respects, proper to proceed upon a voyage for the purpose above mentioned; and from the experience we have had of your abilities and good conduct in your late voyages, have thought fit to entrust you with the conduct of the present intended voyage, and...
Sivu 212 - Mount Erebus was observed to emit smoke and flame in unusual quantities, producing a most grand spectacle ; a volume of dense smoke was projected at each successive jet with great force, in a vertical column, to the height of between...
Sivu 272 - We were now within half a mile of the range of bergs. The roar of the surf, which extended each way as far as we could see, and the crashing of the ice, fell upon the ear with fearful distinctness, whilst the frequently averted...
Sivu 210 - ... feet above the level of the sea, perfectly flat and level at the top, and without any fissures or promontories on its even seaward face. What was beyond it we could not imagine ; for, being much higher than our mast-head, we could not see anything except the summit of a lofty range of mountains extending to the southward as far as the seventy-ninth degree of latitude.
Sivu 273 - A gentle air of wind filled our sails ; hope again revived ; and the greatest activity prevailed to make the best use of the feeble breeze. As it gradually freshened, our heavy ships began to feel its influence, slowly at first, but more rapidly afierwards ; and before dark we found ourselves far removed from every danger.
Sivu 263 - On the 7th we had much better weather, and continued all day running along the perpendicular icy barrier, about one hundred and fifty feet in height. Beyond it the outline of the high land could be well distinguished. At 6 PM we suddenly found the barrier trending to the southward, and the sea studded with icebergs. I now hauled off until daylight, in order to ascertain the trending of the land more exactly. I place this point, which I have named Cape Carr, after the first lieutenant of the Vincennes,...
Sivu xi - ... itself one of the most interesting and important points to which the attention of magnetic inquirers can be turned, as they are no doubt intimately connected with the general causes of terrestrial magnetism, and will probably lead us to a much more perfect knowledge of those causes than we now possess.
