Page 27 - On which the comment may be that one who had studied celestial mechanics as much as the reviewer has studied the general course of transformations, might similarly have remarked that the formula — 'bodies attract one another directly as their masses and inversely as the squares of their distances,' was at best but a blank form for solar systems and sidereal clusters.
Page 248 - These screech-owls seem to be settled in an opinion that the great business of life is to complain, and that they were born for no other purpose than to disturb the happiness of others, to lessen the little comforts, and shorten the short pleasures of our condition, by painful remembrances of the past, or melancholy...
Page 144 - Historical Account of Discoveries and Travels in Africa, from the Earliest Ages to the present Time. By the late John Leyden, MD Completed and enlarged, with Views of the present State of that Continent, by Hugh Murray, FRSE Illustrated by Maps. 2 vol. 8vo. 11. 7s.

Page 219 - The occasional rapid motion of fields, with the strange effects produced on any opposing substance, exhibited by such immense bodies, is one of the most striking objects this country presents, and is certainly the most terrific. They not unfrequently acquire a rotatory movement, whereby their circumference attains a velocity of several miles per hour. A field, thus in motion, coming in contact with another at rest, or more especially with a contrary direction of movement, produces a dreadful shock....
Page 217 - I have observed the growth of ice up to a foot in thickness in such a situation, during one month's frost, the effect of many years, we might deem to be sufficient, for the formation of the most ponderous fields. There is no doubt, but a large quantity of ice is annually generated in the bays, and amidst the islands of...
Page 225 - The place of their retreat, however, is regulated by various circumstances ; it may sometimes depend on the quality and quantity of food occurring, the disposition of the ice, or exemption from enemies. At one time, their favourite haunt is amidst the huge and extended masses of the field ice ; at another, in the open seas adjacent. Sometimes the majority of the whales inhabiting those seas, seem collected within a small and single circuit ; at others, they are scattered in various hordes, and numerous...
Page 82 - That this deviation varies with the dip of the needle, the position of the compass, and the direction of the ship's head. It increases and diminishes with the dip, and vanishes at the magnetic equator. It is a maximum when the ship's course is W. or E., and it is proportional to the sines of the angles between the ship's head and the magnetic meridian.
Page 328 - You request a detailed account of my observations relative to the serpent. I saw him on the fourteenth ultimo, and when nearest I judged him to be about two hundred and fifty yards from me. .At that distance I judged him (in the largest part) about the size of a half barrel, gradually tapering towards the two extremes. Twice I saw him with a glass, only for a short time, and at other times with the naked eye,
Page 355 - Practical Inquiry into the Causes of the frequent failure of the Operations of Depression, and of the Extraction of the Cataract, as usually performed, with the Decriptiou of a Series of New and Improved Operations, by the practice of which most of these causes of failure may be avoided.
Page 220 - In one place, hummocks had been thrown up to the height of twenty feet from the surface of the field, and at least twenty-five feet from the level of the water ; they extended fifty or sixty yards in length, and fifteen in breadth'., forming a mass of about two thousand tons in weight. The majestic unvaried movement of the ice, — the singular noise with which it was accompanied, — the tremendous power exerted, — and the wonderful effects produced, were calculated to excite sensations of novelty...
