Seite 106 - Society of London, a present of a glass tube with some account of the use of it in making such experiments. I eagerly seized the opportunity of repeating what I had seen at Boston; and, by much practice...
Seite 112 - Make a small cross of two light strips of cedar, the arms so long as to reach to the four corners of a large thin silk handkerchief when extended ; tie the corners of the handkerchief to the extremities of the cross, so you have the body of a kite ; which, being properly accommodated with a tail, loop, and string, will rise in the air, like those made of paper; but this being of silk is fitter to bear the wet and wind of a thundergust without tearing.
Seite 110 - Chagrined a little that we have been hitherto able to produce nothing in this way of use to mankind ; and the hot weather coming on, when electrical experiments are not so agreeable, it is proposed to put an end to them for this season somewhat humorously in a party of pleasure on the banks of Skuylkil.

Seite 115 - The king's changing his pointed conductors for blunt ones is, therefore, a matter of small importance to me.

For it is only since he thought himself and family safe from the thunder of heaven that he dared to use his own thunder in destroying his innocent subjects...
Seite 130 - ... a current from a trough, if not increased, is but slightly diminished in passing through a long wire is certain. . . .
