Pagina 72 - Though I look old, yet I am strong and lusty: For in my youth I never did apply Hot and rebellious liquors in my blood; Nor did not with unbashful forehead woo The means of weakness and debility; Therefore my age is as a lusty winter, Frosty, but kindly: let me go with you; I'll do the service of a younger man In all your business and necessities.
Pagina 220 - I sought a resting-place, found one, and contrived to sit ; but when my weight bore on the body of an Egyptian, it crushed it like a band-box. I naturally had recourse to my hands to sustain my weight, but they found no better support ; so that I sunk altogether among the broken mummies, with a crash of bones, rags, and wooden cases, which raised such a dust as kept me motionless for a quarter of an hour, waiting till it subsided again.
Pagina 163 - The suddenness of the transition/ writes Wollaston, ' from perfect hearing to total want of perception, occasions a degree of surprise which renders an experiment of this kind with a series of small pipes, among several persons, rather amusing. It is curious to observe the change of feeling manifested by various individuals of the party in succession, as the sounds approach and pass the limits of their hearing. Those who enjoy a temporary triumph are often compelled...
Pagina 220 - ... me with horror. The blackness of the wall, the faint light given by the candles or torches for want of air, the different objects that surrounded me, seeming to converse with each other, and the Arabs with the candles or torches in their hands, naked and covered with dust, themselves resembling living mummies, absolutely formed a scene that cannot be described.

Pagina 362 - Iron is rendered magnetical if scoured or filed, bent or twisted, when in the position of the magnetic axis, or near this position ; the upper end becoming a south pole, and the lower end a north pole...
Pagina 221 - It was* choked with mummies, and I could not pass without putting my face in contact with that of some decayed Egyptian ; but as the passage inclined downwards, my own weight helped me on: however, I could not avoid being covered with bones, legs, arms, and heads, rolling from above.
Pagina 129 - To explain the unusual refraction of island crystal by pression or motion propagated has not hitherto been attempted (to my knowledge) except by Huygens, who for that end supposed two several vibrating mediums within that crystal. But when he tried the refractions in two successive pieces of that crystal and found them such as is mentioned above, he confessed himself at a loss for explaining them.
Pagina 128 - Every ray of light has therefore two opposite sides originally endued with a property on which the unusual refraction depends, and the other two opposite sides not endued with that property.
