Not illustrated. 1903 Excerpt: ... from them, but if he then brings the coins a little forward so that their edges touch beyond the tip of his tongue, and thus he connects the two plates of the battery of coins, he will feel and taste his battery in action; if he separates the edges of the coins, he will notice that the battery ceases to act. He will also discover that the battery has left a disagreeable taste in his mouth, which has been caused by the metals being dissolved, with the assistance of electricity, when the battery was acting. This experiment will give him a practical idea of the action of a galvanic battery, and the effect of connecting and disconnecting the plates for the passage of a current of electricity. It may be said that so soon as the plates are joined, electricity is formed, and the plates begin to be acted upon and dissolved by the acid; the electricity passes through the point of contact from the first plate to the second, then from the second to the first through the tongue, and the circuit is complete. But so soon as the contact of the first and second plate is broken, so that the current of electricity cannot pass, the acid ceases to act upon the plates, and electricity ceases to be formed; for this reason, the plates of a battery used for electric bells can remain in the acid solution for a great length of time, when not being used, without materially wasting; electricity is only formed, and the plates dissolved, when the bell is actually ringing. When the amateur wishes to fit electric bells to his house, he will, of course, first decide as to the number of rooms to which he will fit his bells, and the position of his bell-pulls, or connections, in each room. Having settled this, he will buy an indicator; this is a shallow box with glass front, under which the...
