Mild Steel Dustbins Sub-committee. —The need for a New Zealand Standard Specification for Mild Steel Dustbins —particularly for the purpose of having a uniform specification which can be written into by-laws of those local authorities controlling the collection of refuse —was made apparent to the Institute. Such questions as reasonable sizes to facilitate handling, and effective shape, were involved. The draft New Zealand Standard Specification is in the course of circulation to the parties. 4. Electrical Engineering Divisional Committee. New Zealand Standards issued are as follows :— N.Z.S.S. 51 Electricity Meters ; being B.S.S. 37-1937 (revision). 58 Parallel-sided Carbon Brushes for D.C.
