| contd :- -2- For instance, the modifications which have been carried out on the S.S. exhaust, we should like to apply to the 20 HP. As regards the performance and smoothness, this can be judged perfectly well with the car as it is. We should be glad to hear from Sales when it will be convenient to make this test.
