AN ODORIFEROUS ACCUMULATOR.

Mr W. 11. Preoee thus speaks of a new accumulator that he saw at a recent Munich Electrical Exhibition : It was the invention of Mr Shulzc, of Slrnssburg. The noveltyis th.it Mr Shulze takes his lead plates and coats them with a thin superficial layer of plumbic sulphide. (I,'bS). Tho lead plates, very finely grooved, are heated in sulphur, in what form 1. do not know, but they como out coated with a superficial layer of what wo used to know as the black sulphuret of lead, this is put into a bath of sulphuric acid, and the result is that there is sulphide of lead opposed to sulphide of load, through which the current goes, with the result that on the one plate the hydrogen and the water combine with the sulphur, forming that sweet and delightful perfume called sulphurated hydrogen ; indeed, the effect of the current on this plato in producing sulphurcted hydrogen was only too evident in tiie neighborhood of this secondary battery, for the .smell of rotten eggs is sweet to the odor of Mr Shulze , s secondary battery. When the operation is conq:>lcte, and when everybody is driven away, then it is said that the battery is ready for action. Each cell when complete weighs 'JO pounds, and it takes a current of 4 amperes for 80 hours to form it. The efficiency is small.
