Automobiles figure in '25 per cent of the accidents occurring nowadays, according to an analysis of style changes in accidents made public yesterday by W. McK. Hillas, vice president in charge of the accident bureau of the Fidelity and Casualty Company of New York. Injuries due to operation of motor cars average 700 a day. Things were different two decades ago. In 1911 only one in every forty accident cases involved the automobile, whereas the major cause of street accidents was the horse-drawn vehicle, with the bicycle as runner-up.

"Airplanes have not yet become sufficiently common to figure prominently in our statistics," said Mr. Hillas, “but travel by air is on the increase, so that the hazards of aviation are certain to have a definite effect upon the accident records of the future."
