Strana xxii - Hudson's Bay Company, and his attempt to establish a Colony on the Red River; with a Detailed Account of his Lordship's Military Expedition to, and Subsequent Proceedings at Fort William, in Upper Canada.
Strana 324 - B. placed the fluids in a trough formed by two plates of glass cemented together at an angle. The eye being necessarily placed at one end, some of the cement which had been pressed through between the plates appeared to be arranged into a regular figure. The symmetry of this figure being very remarkable, Dr B.
Strana 332 - ... instrument is directed, if it only be in its proper place the effect just described is sure to take place, and with an endless variety. In this respect, the kaleidoscope appears to be quite singular among optical instruments. Neither the instrument of Bradley, nor the experiment or theorem in Wood's book, have any resemblance to this ; they go no further than the multiplication of the figure.
Strana 9 - ... withhold their protection from the fine arts, and debar themselves of the pleasures derived from works of literature and taste. Strange and novel as the assertion may appear,, it is no less true, that .the advantages and enjoyments which these studies and pursuits afford, are not only obtained without any expense to the country in which they are encouraged, but, that they actually repay, in wealth and emolument, much more than they require for their support.

It is quite true, that the quiet way in which they visit us is against such an origin ; it seems, however, that any power which would move a body 6000 feet in a second, that is, about three times the velocity of a cannon ball, would throw it from the sphere of the moon's attraction into that of our earth.

Strana 294 - While we are considering the possibility of these considerations it may be remembered, that in the great laboratory of the atmosphere, chemical changes may happen, attended by the production of iron and other metals ; that at all events such a circumstance is within the range of possible occurrences ; and that the meteoric bodies which thus salute the...
Strana 182 - It is generally admitted that, for the last four hundred years, an extensive portion of the eastern coast of Old Greenland has been shut up by an impenetrable barrier of ice, and, with it, the ill-fated Norwegian or Danish colonies, which had been established there for more than an equal length of...
Strana 168 - The length of the pendulum vibrating seconds in the latitude of London forms the standard of the British measure of extension.
