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...
