Pagina 260 - God has suspended Here on its fragile stalk, to direct the traveller's journey Over the sea-like, pathless, limitless waste of the desert.
Pagina 193 - 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.

Pagina 459 - In a very early stage of electro-magnetic experiments it had been suggested that an instantaneous telegraph might be established by means of conducting wires and compasses. The details of this contrivance are so obvious, and the principle on which it is founded so well understood, that there was only one question which could render the result doubtful ; and this was, — is there any diminution of effect by lengthening the conducting wire?
Pagina 182 - 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...
