Strona 22 - Beneath a shady tree the hero spread His table on the turf, with cakes of bread, And with his chiefs on forest fruits he fed.
Strona 247 - ... them steady. The habit of using the stilts is acquired early, and it appeared that the smaller the boy was, the longer it was necessary to have his stilts. By means of these odd additions to the natural leg, the feet are kept out of the water, which lies deep during winter on the sands, and from the heated sand during the summer: in addition to which, the sphere of vision over so perfect a flat is materially increased by the elevation, and the shepherd can see his sheep much farther on stilts...
Strona 282 - that the ancient game of goff is still much practised in Scotland." " It is," replied the vicar. " In the reign of Edward III. the Latin name cambuca, a crooked club, or staff, was applied to this pastime, because it was played with such an instrument.
Strona 99 - Your ancient acquaintances," observed Mr Seymour, " entertained some very strange notions touching this said subject of motion. If I remember right, Diodorus denied its very existence ; but we are told that he did not himself remain unmoved when he dislocated his shoulder, and the surgeon kept him in torture while he endeavoured to convince him, by his own mode of reasoning, that the bone could not have moved out of its place. We have, however, at present, nothing to do with the ancients ; the philosophers...
Strona 207 - Your are not quite correct," said Mr Seymour ; " the water does not fly off in a right line from the centre, but in a right line in the direction in which it was moving at the instant of its release...
Strona 279 - Anciently they played with the naked hand, then with a glove, which, in some instances, was lined; afterwards they bound cords and tendons round their hands, to make the ball rebound more forcibly; and hence, says St. Foix, the racket derived its origin.
Strona 206 - Caroline. This is a little more difficult to comprehend than compound motion in straight lines. Mrs. B. You have seen a mop trundled, and have observed, that the threads which compose the head of the mop fly from the centre ; but being confined to it at one end, they cannot part from it; whilst the water they contain, being unconfined, is thrown off in straight lines. Emily.
Strona 70 - ... than if the wind blew towards us. This uniform velocity of sound, enables us to determine the distance of the object, from which it proceeds; as that of a vessel at sea, firing a cannon, or that of a thunder cloud. If we do not hear the thunder, till half a minute after we see the lightning, we conclude the cloud to be at the distance of six miles and a half.
Strona 138 - An ARC is any part of a circumference. 5. A CHORD is a straight line joining the extremities of an arc. Any chord belongs to two arcs : the smaller one is meant, unless the contrary is expressed.
Strona 176 - Well said, my boy ; the ablest mathematician could not have given a more correct answer. The block was actuated by two forces at the same time ; and, since it could not move in two directions at once, it moved under the compound force, in a mean or diagonal direction, proportioned to the influence of the joint forces acting upon it. You will, therefore, be pleased to remember, it is a general law, that where a body is actuated by two forces at the same time, whose directions are inclined to each...
