Page 2 - K respectively corresponding to a temperature of 0° C. and a pressure of 760 mm. of mercury. The...
Page 115 - ... slightly exceeding a mile. Taking the value given by Drude for the energy in the visible part of the spectrum of a standard candle, the amount of energy falling on 1 square centimetre of the plate is 5 x 10"6 ergs per sec.
Page 315 - The author wishes to acknowledge his indebtedness to the Government Grant Committee of the Royal Society for the means of purchasing some of the apparatus used in these experiments, and also to Prof.
Page 3 - K which is independent of v, and we obtain Maxwell's law : The coefficient of viscosity of a gas is independent of its density. In spite of its apparent improbability, this law was predicted by Maxwell on purely theoretical grounds, and its subsequent experimental confirmation has constituted one of the most striking triumphs of the Kinetic Theory. Some of the physical consequences of this law are interesting, and occasionally...
Page 115 - In order to get some idea of the energy of the light falling on the platen in these experiments a plate of the same kind was exposed at a distance of two metres from a standard candle till complete development brought it up to the standard of blackness. Ten seconds sufficed for this, A simple calculation will shew that the amount of energy falling on the plate during the longest exposure was the same as that due to a standard candle burning at a distance slightly exceeding a mile.
Page 115 - The remaining times of the exposure were taken from the first in the inverse ratio of the intensities. The longest time was 2000 hours or about 3 months. In no case was there any diminution in the sharpness of the pattern although the plates did not all reach the standard blackness of the first photograph. In order to get some idea of the energy of the light falling on the plates in these experiments, a plate of the same kind was exposed at a distance of two metres from a standard candle till complete...
Page 316 - ... to her story. HISTORY OF ENGLAND BOOK I THE MINGLING OF THE RACES. FROM THE EARLIEST TIMES TO THE NORMAN CONQUEST INTRODUCTION IT is a commonplace to say that the British are a people of mixed blood. I hope, in this First Book, to indicate a little how, when and why this mingling of races occurred. It may be as well to say, at the outset, that the entrance into our island of the races who people it to-day was completed in main outline at the time of the Norman Conquest. With that event, which...
