Electeical Appliances.

Two of the most popular exhibits in this hall are the displays of electrical appliances, shown by Mr. O. Hull and Mr A. Smith. The former gentleman exhibits and explains a collection of electrical apparatus, most of which was made by Mr. Cunnington. His object is to demonstrate that the most elaborato electric appliances can bo success-fully produced in local workshops. The exhibit comprises models of various kinds of phybiological and other coils, a storage battery with incandescent lamps attached, and a page 17 miner's electric safety-lamp of four standard candle power, shown by Mr. Cederholm, and placed side by side with an old fashoned safety (?) lamp found on the scene of the disastrous Kaitangata explosion in 1879. Mr. Smith's exhibit illustrates electricity as applied to the purposes of commercial and social intercourse. He has electric bells, hotel, and office indicators, telephones, switches and an elaborate battery for medical purposes. The gem of his collection is, perhaps, an exquisitely made coil of the Rhumkorff type, by means of which an electrical illumination is displayed. Mr. Smith also exhibits a motor, patented by himself, and capable of driving a sewing machino or other small mechanical contrivance. Mr. W. Partes also exhibits electric coils used for medical galvanism.
