USE OF SODIUM PHOSPHATE Na{Mr Nadin}₂H P O₄. --------------------- Please note that it has been decided that in view of the tendency to prime which occurs when the sodium phosphate is added to the water, it has been decided for the present that we are not to recommend the use of this to customers. In the case of Mr. Short's car, priming occurred, and although a double quantity of sodium phosphate had been added it shows that we are too near the margin of safety in regard to losing water, to permit us to go ahead with this scheme.
