recorded, whilst for the front are substantially the same. This suggests vapour pocketing at the front of the water pipe.

Inclination tests on hangar test stands with standard cylinder construction have shewn that the position of the vapour pockets change with the attitude of the engine. This tends to show that with our present schemes of single inlet and multi outlets, the problem of eliminating vapour pockets is almost insuperable.

The success which has attended the latest two-piece cylinder construction operating at high powers evaporatively cooled, supports the theory that in the light of our present knowledge of water distribution for evaporative cooling, the correct procedure is to lead the water in at numerous points with the object of preventing the formation of vapour pockets rather than attempt to release the vapour after a pocket has been formed.
