The best solution for crankchamber fumes getting into THE body of a car with enclosed front seats, is the scheme of connecting the crankchamber breather to the intake of the car-buretter. This has not yet been made standard.

We have adopted this on Goshawk ll., and unless we find some objection, or that it is inefficient, we are arranging this to be standard on present 40/50, and on all other chassis.

SPRINGS X.2628.

Flexible and frictionless springs with ample bump clearance will always give a sense of sea-sickness to a nervous person. You will remember my constant and persistent advice is to us shock-dampers, but when these have been fitted in several, in most cases they were removed as most people object to the friction, and the slight harshness it creates, preferring the unsteady riding which leads to sea-sickness. The most perfect course is to use shock-dampers of the progressive order which I have on 6.EX at W.W.

If you take away the road springs you will not get sea-sickness, but a good healty shaking - probably one gets a little of this in a Rover.

Remember, in nearly all these cases, it is "one cannot have everything".

Kindly do your best to avoid using MY time, repeatedly going over the same ground.
