And yet further to show you, that White Bodies Reflect the Beams From them, and not Towards themselves, Let me add, that Ordinary Burning-glasses, such as are wont to be employ'd to light Tobacco, will not in a great while Burn, or so much as Discolour a Sheet of White Paper.
He explained the nature of burning-glasses, and of glasses which magnify and diminish, the microscope and the telescope. He discovered the composition of gunpowder. He ascertained the true length of the solar year; and his theory was afterwards brought into general use, but upon a narrow scale, by Pope Gregory XIII, nearly three hundred years after his death.
"Ladies," said he, turning to his family, "Miss Temple, teachers, and children, you all see this girl?" Of course they did; for I felt their eyes directed like burning-glasses against my scorched skin.
"'Bless me! what's all this? cried Lady Margaret, dropping my palsied arm, and gazing on me as if she expected me to talk like a hero. "'Oh, said I, 'eh-e-m, eh-e-m, I will exp lain to-morrow, ehem, e-h-e-m. I made to the door; all the eyes in the room seemed turned into burning-glasses, and blistered the very skin on my face.
I must here inform my reader that the frontiers of the enchanted region, which I have before described, were inhabited by the species of Mixed Wit, who made a very odd appearance when they were mustered together in an army. There were men whose bodies were stuck full of darts, and women whose eyes were burning-glasses; men that had hearts of fire, and women that had breasts of snow.
A tradition has prevailed, that the Roman fleet was reduced to ashes in the port of Syracuse, by the burning-glasses of Archimedes; and it is asserted, that a similar expedient was employed by Proclus to destroy the Gothic vessels in the harbor of Constantinople, and to protect his benefactor Anastasius against the bold enterprise of Vitalian.
"I've had a hunch it would come to that," the near-sighted one replied. "Every time I look at him I see a bleedin' bullet-hole in his abominable regions, about here." He laid a finger upon his stomach, and Glass felt a darting pain at precisely the same spot. It was as agonizing as if Willie's spectacles were huge burning-glasses focussing the rays of a tropic sun upon his bare flesh.
When a warm rain in the middle of the winter melts off the snow-ice from Walden, and leaves a hard dark or transparent ice on the middle, there will be a strip of rotten though thicker white ice, a rod or more wide, about the shores, created by this reflected heat. Also, as I have said, the bubbles themselves within the ice operate as burning-glasses to melt the ice beneath.
It should be observed that neither Polybius nor Plutarch mentions the use of burning-glasses in connection with the siege of Syracuse, nor indeed are these referred to by any other ancient writer of authority. Nevertheless, a story gained credence down to a late day to the effect that Archimedes had set fire to the fleet of the enemy with the aid of concave mirrors.
They might have been burning-glasses, she felt so hot and frightened. "Come, did this young gentleman ever give you a kiss?" "Yes, Sir," murmured poor Harry, almost under her breath. "Did you say 'Yes' or 'No?" inquired the judge, dipping his pen in the ink. "I said 'Yes, my lord," said the unhappy Harry. "There were more kisses than one, now, I dare say," said Mr.
