الصفحة 312 - Bind up those tresses : O, what love I note In the fair multitude of those her hairs ! Where but by chance a silver drop hath fallen, Even to that drop ten thousand wiry friends Do glue themselves in sociable grief, Like true, inseparable, faithful loves, Sticking together in calamity.
الصفحة 76 - Turner, of Edinburgh, has been collecting and investigating a number of rare prints of sperm whales stranded on European coasts at the end of the sixteenth and beginning of the seventeenth centuries. One of
الصفحة 268 - When daisies pied and violets blue, And lady-smocks all silver white, And cuckoo-buds of yellow hue Do paint the meadows with delight.
الصفحة 197 - Oh, he's a lovely gentleman ; Romeo's a dish-clout to him ; an eagle, madam, Hath not so green, so quick, so fair an eye As Paris hath.
الصفحة 330 - by which currents passing through a circuit, or branch circuit, are measured, and graphically recorded. It is well known that when an electric current passes through a conductor heat is generated, which, according to Joule, is proportionate in amount to the resistance of the conductor, and to the square of the current which passes through it in a unit of time,
الصفحة 169 - to place before the reader a fairly complete, and yet a clear and succinct statement of the facts of modern chemistry, whilst at the same time entering so far into a discussion of chemical theory as the size of the work and the present transition state of the science permit, special attention
الصفحة 138 - molecules which are advancing towards that pole. The conflict occurs at the boundary of the dark space, where the luminous margin bears witness to the energy of the collisions. When the exhaustion is sufficiently high for the mean length of path between successive collisions to be greater than the distance between the fly and the glass, the
الصفحة 313 - time is greatest. Sir W. Thomson (see Thomson and Tait, "Nat. Phil.," App. D) considers the cooling of "a solid extending to infinity in all directions, on the supposition that at an initial epoch the temperature has had two different constant values on the two sides of a certain infinite plane.

الصفحة 138 - actually illuminates the lines of molecular pressure caused by the electrical excitement of the negative pole. The thickness of the dark space is the measure of the mean length of the path between successive collisions of the molecules. The extra velocity with which the molecules rebound from the excited negative pole keep back the more
