Page 26 - And it came to pass on the third day in the morning, that there were thunders and lightnings, and a thick cloud upon the mount, and the voice of the trumpet exceeding loud ; so that all the people that was in the camp trembled.
Page 330 - ... Give thy thoughts no tongue, Nor any unproportion'd thought his act. Be thou familiar, but by no means vulgar. Those friends thou hast, and their adoption tried, Grapple them to thy soul with hoops of steel; But do not dull thy palm with entertainment Of each new-hatch'd, unfledged comrade.
Page 134 - 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 Thunder Gust without tearing.

Page 130 - If any one should undertake to prove, as a clear consequence of the phenomenon, that thunder is, in the hands of nature, what electricity is in ours — that those wonders which we dispose at our pleasure are only imitations on a small scale of those grand effects which terrify us, and that both depend on the same mechanical agents — if it were made manifest that a cloud prepared by th...

Page 134 - At this key the phial may be charged; and from electric fire thus obtained, spirits may be kindled, and all the other electric experiments be performed, which are usually done by the help of a rubbed glass globe or tube, and thereby the sameness of the electric matter with that of lightning completely demonstrated.
