Moreover, a tube having its mouthturned toward the front and placed a short distance from the forward corner, ap-proximately in the po-sition represented byIV, did not show thefull pressure as re-. the. car. To determine how far the compressed air cone ex-tended in front of the moving car, the ends of the tubes werebent backwards, and were also extended up to a point in front of the surface of the front end of the car, meters on either side of the center line of the car. Inrunning in the opposite direc-tion, these tubes were used toascertain the state of the air 1 , j \ \ .!> 1 I \ \ 1 I i ! / \ 1 drawn along- at the rear end I 1 1 / \ i of the car. | 1 I / / / \ \ 1 hs
