The comparison of weather-forecasts with the weather subsequently experienced in 1899 was as follows :-
Success 61 %, partial success 33 %, partial failure 5 %, total failure 1 %.
Following the method used in meteorological offices and taking the sum of total and partial success as a measure of success, and the sum of total and partial failure as a measure of failure, we find finally that :-
94% of the weather forecasts were successful in 1899.
3. The China Coast Meteorological Register was printed every morning at the Observatory, and information regarding storms was telegraphed and exhibited on notice boards as often and as fully as such information could be justified by the weather telegrams received.
