Stran 14 - Save base authority from others' books. These earthly godfathers of heaven's lights That give a name to every fixed star Have no more profit of their shining nights Than those that walk and wot not what they are.
Stran 178 - If seven maids with seven mops Swept it for half a year, Do you suppose," the Walrus said, "That they could get it clear?
Stran 163 - Others apart sat on a hill retired, In thoughts more elevate, and reasoned high Of Providence, Foreknowledge, Will, and Fate— Fixed fate, free will, foreknowledge absolute — And found no end, in wandering mazes lost.
Stran 247 - Edinburgh, a Member of the Institution of Civil Engineers, and of the Institution of Mechanical Engineers, and in 1883 he received the honorary degree of LL.D. from the University of Glasgow. He died on the 12th of June, 1885, after a few days' illness, due to a slight surgical operation.
Stran 107 - The book is primarily written to meet the needs of students preparing for the examinations of the Conjoint Board of the Royal Colleges of Physicians and Surgeons of England.
Stran 19 - I will not dwell on this beautiful proof of this, as you will no doubt be able to hear it from himself. Now mass cannot be annihilated, and the deficit can only represent the mass of the electrical energy set free in the transmutation.
Stran 139 - He contemplates the law and lawyers of to-day with a temperamental lack of appreciation. This may have made him negligent of Justinian and unjust to Rome as a whole.
Stran 19 - ... life. The radio-active elements must have been formed at no very distant date; and their synthesis, unlike the generation of helium from hydrogen, is endothermic. If combinations requiring the addition of energy can occur in the stars, combinations which liberate energy ought not to be impossible. We need not bind ourselves to the formation of helium from hydrogen as the sole reaction which supplies the energy, although it would seem that the further stages in building up the elements involve...

Stran 18 - Now, on the contraction hypothesis the change of density must amount to at least 1 per cent, in 40 years. (I give the figures for 8 Cephei, the bestknown variable of this class.) The corresponding change of period should be very easily detectable. For 8 Cephei the period ought to decrease 40 seconds annually. Now 8 Cephei has been under careful observation since 1785, and it is known that the change of period, if any, must be very small. S. Chandler found a decrease of period of %0 second per annum,...
