| -2- continuously positively pumped again to the engine cylinder heads, the whole system being closed. The provision of a safety valve can be of relieving pressure at perhaps 4 or 5 lbs per square inch. I understand that employing the steam system would mean altogether more easy dissipation of the heat; the radiator itself certainly would be no larger, probably smaller. I do not know whether you have, or to what extent, carried out experiments on these lines. If you would be good enough to give me this information, we shall then know what course to pursue, either in awaiting further results from you or making a point of urging the wisdom of initiating experiments with this modified system of cooling.
