Battery: a Home-Made Leclanché Cell with a Canvas Bag (Hasluck, 1908)
A wet cell for bell work: a carbon plate packed in a canvas bag with crushed coke and manganese dioxide, an amalgamated zinc strip beside it, in a quart jam jar of sal-ammoniac solution. It gives a strong current in short bursts and recovers between them.
Two such cells ring a 2 1/2 or 3 in bell.
