Electric Bells, and All About Them. By S. R. Bottone.

(Whittaker and Co.)-We had occasion to notice Mr. Bottone's " Electrical Instruments for Amateurs " not long ago, and now we must class Electric Bells in the same category of useful handbooks. This volume is doubtless intended more for the bell-fitter than the amateur ; the former certainly requires it as much, and often more, than the latter, who is generally more open to hints. Both will find here all that they want to know.
