With reference to the above and Mr Royce's sheets dated June 14th in which he asks whether the noise is due to the side shaft, or to the reverse pinion, I shall be glad if you will refer him to experiments which I Demonstrated to you the other day, and which I have already reported, to show that the noise is due to the side shaft and how such is effected by the question of oil level.
