ls in parallel,and they must be large and of energetic action, andmust therefore contain strong excitants, so that the zincsmust be withdrawn after each application, or they wouldcontinue to be dissolved. For a house installation, a switch-board such as MilneMurrays attached to the electric light mains is much tobe preferred, but failing this 20 to 40 large-size Leclanches,combined with an induction coil to be worked either by acouple of the Leclanches or by a separate bottle bichromate,and kept in a cupboard or placed within an electricalcabinet (Fig. 86), would probably be the most suitableand reliable battery for galvanism, faradism, electro-diagnosis, and electrolysis. For cautery and light, a special bichromate or accumu-lator battery may be used. 140 A Manual of Practical Medical Electricity For portable purposes, a combined or separate galvanicand faradic battery composed of small Hellesens orLeclanches (Fig. 87) is best.
