making an examination of this. When this has been done and we have found how to make the way through bigger it will be re-erected and tested at high speeds on the dynamometer. I will report the results of the tests as soon as they have been made.

X.93 - Explosions in the Silencer.

This matter is so very old that we are sending to Mr Royce a copy of his original notes on the subject as it is very likely he will cancel some of the instructions or revise them.

X.457 - Steering Wobbles.

I have made several tests and obtained some particulars of various makes of cars as follows.

Daimler.

Dia. of steering wheel 16"
Wire wheels 920 X 120.
Steering reversible one way only, i.e. to off side.
I have not yet investigated as to why this should be. Possibly a different kind of thrust bearing one way or may be something wrong in fitting up.

To move the road wheels through 60° the steering wheel moves through 552°. Full lock of front wheels is 62°.

This car wobbles quite as badly as R.R. when out of balance but is not so pronounced on the steering wheel
