In the further comparison of the two radiators, it would be as well to only fill them to the desired level. That is to say, after filling the radiator it would be as well to take one gallon of water out. This is what I intended should be done, as I think we carry too great a weight of water and the tank is really too large, and ought not to be filled up so much. With reference to the one gallon lost directly the water boils, we may be able to reduce this by altering the water piping round the engine, especially the delivery pipes. We should like to push forward the Northcliffe engine with all possible speed, although it may not be completed in every detail (with reference to points such as electro dynamo self starter) it would be useful to get to know something of such points as the above.
