"An observer was called in a case where it was alleged that the plaintiff had been injured by being pitched through the open window of a car. It was claimed that she was trying to shut the window on account of the raw, cold weather and, as the car reached a curve, she was suddenly thrown headlong into the street. The weather record showed that it was a warm and sunny day. "The question as to whether a sidewalk was sufficiently slippery to make it dangerous for travel frequently comes up in court. One such case, I remember, was that of a man who asked damages from a jitney driver for starting his bus before he had alighted. The driver declared that the passenger slipped and fell on the ice in the gutter, several feet away from the bus. The plaintiff declared that it was a warm day and that there was no ice. The weather record showed rain the day before, with a severe frost during the night, precisely the conditions to support the jitney-driver's story. "Many accidents are alleged to have been due to fog. The weather expert is called upon to testify to the degree of visibility permitted by atmospheric conditions. One man who was accused of murder and who undoubtedly would have been convicted, was positively identified by the wife of the murdered man, the woman declaring that she saw him at a certain hour of the evening passing in front of the house. The Weather Records showed conclusively that, at that hour, owing to the excessive cloudiness of the atmosphere, it would have been impossible for the woman to identify the suspect, even at half the distance. "Wind records are often very important. In April, 1902, a severe storm moved over the middle western states, and, at one place in Indiana, it developed such velocity as to start in motion an empty box car standing on a railway siding. It was carried on to the main track, the derailing switch not being turned, and ran for two miles before the wind, the grade being slightly up-hill. It finally collided with a passenger train and several persons were killed. The railroad company produced the weather records to show that a storm of such violence was outside the common run of events, seeking thereby to lessen the amounts awarded for damages.
