Page 12 - The PRESIDENT then delivered his Address, (p. 65.) It was proposed by Mr. LATHAM, seconded by Mr. FIELD, and resolved:— " That the thanks of the Society be given to the President for his Address, and that he be requested to allow it to be printed in the Quarterly Journal of the Society.
Page 284 - But Linden saw another sight, When the drum beat at dead of night, Commanding fires of death to light The darkness of her scenery. By torch and trumpet fast arrayed, Each horseman drew his battle blade, And furious every charger neighed, To join the dreadful revelry.
Page 148 - I look at the geological record as a history of the world imperfectly kept, and written in a changing dialect ; of this history we possess the last volume alone, relating only to two or three countries. Of this volume, only here and there a short chapter has been preserved ; and of each page, only here and there a few lines.
Page 540 - On returning to our anchored boat, we learned that when the flag was hoisted the horn-sounds were heard, that they were succeeded after a little time by the whistle-sounds, and that both increased in intensity as the evening advanced. On our arrival of course we heard the sounds ourselves.
Page 38 - With the gauge 3 millims. below the barometer, the ascension of the pith when a hot body was placed beneath it was equal to what it had been in air of ordinary density ; whilst with the gauge and barometer...
Page 297 - Williams finds that menstruation appears essentially to consist, not in a congestion or a species of erection, but in growth and rapid decay of the mucous membrane. The menstrual discharge consists chiefly of blood and of the debris of the mucous membrane of the body of the uterus.

That enemy has been proved to be not rain, nor hail, nor haze, nor fog, nor snow — not water in fact in either a liquid or a solid form, but water in a vaporous form, mingled with air so as to render it acoustically turbid and floeculent.
Page 66 - The gun failed to be heard at a distance of 2-8 miles, and it yielded only a faint crack at 2^ miles. Meanwhile this investigation has given us a knowledge of the atmosphere in its relation to sound, of which no notion had been previously entertained. While the velocity of sound has been the subject of refined and repeated experiments, I am not aware that since the publication of a celebrated paper by Dr. Derham in the ' Philosophical Transactions...
Page 67 - I say, expresses the opinion generally entertained, " clear, still air" being regarded as the best vehicle for sound. We have not, as stated above, experimented in really dense fogs; but the experiments actually made entirely destroy the notion that clear weather is necessarily better for the transmission of sound than thick weather. Some of our days of densest acoustic opacity have been marvellously clear optically, while some of our days of thick haze have shown themselves highly favourable to...
Page 40 - The action of the incandescent spiral was now found to be energetically repellent, whether it was placed above or below the brass ball. The fingers exerted a repellent action, as did also a warm glass rod, a spirit-flame, and a piece of hot copper." In order to decide once for all whether these actions really were due to air-currents, a form of apparatus was fitted up which, whilst it would settle the question indisputably, would at the same time be likely to afford information of much interest....
