| -3- noise and the only thing a passenger feels is the reatrda-tion. The front brakes do not appear to give any tendency to skid; this is probably because the complete braking effort is not very great and only a proportion of this of course falls on the front wheels. I think it is of importance to obtain particulars of the various leverages to the front and back wheel. The body was fairly free from rattles but boomed extremely badly at speeds of 25 to 35 miles per hour; this is apparently due to the large sheets of glass used for the windows, as it practically disappeared if the two side windows were let down. The vibration however could still be felt. The bonnet developed a bad knock [handwritten correction above strikethrough: mark], apparently due to the end ways movement, after a run of about 90 to 100 miles. The springing of the car although not good could not be completely condemned. I should term it "fair".
