EXPERIMENT STATION RECORD. 



of the time of year, as well as of the altitude of the station, it is found that in the 

 majority of causes snowj- thunderstorms occurred when snowy weather was the nor- 

 mal condition of affairs. There are ]>ut few records of snow falling out of season as 

 a result of the sudden cold produced by thunderstorms. These statistics, so far as 

 they go, are interesting as affecting the theory that liy bomliarding a thunderstorm 

 the hail is transformed into snow. If snow' frequently falls after a storm-cloud has 

 been bombarded, and rarely under other circumstances, the theory in question 

 obtains support. But, as Professor Monti points out, we have not at present suffi- 

 ciently complete statistics to enable anj- very definite conclusions to be drawn."

 219-231). — This summary includes notes on the weather and tabulated daily and 

 monthly records of observations at the station at AVooster, Ohio, on temperature, 

 precipitation, cloudiness, direction of the wind, etc., and for comparison, similar 

 data for previous yeai-s and for other parts of the State. The following is a sunniiary

 derstorms about the different quarters of the moon as shown by data recorded at 

 Greenwich. The results are compared with those reported by Hann. "All agree 

 in showing a larger percentage [of thunderstorms] about new moon than about full 

 moon anil in the two earlier ])hases thau in the two later."
