The Rainfall at the Ben Nevis Observatory was measured by a gauge 5 inches in 

 diameter, read hourly to 0"00 1. inch, and the amount is recorded in the tables, the entry 

 under each hour being the amount for the 60 minutes ending at that hour. 



The Rainfall at the Fort- William Observatory is taken from the trace of the 

 Beckley self-recording rain-gauge there. Up to 31st December 1903 the amount was 

 measured to 0*001 inch for the same hourly periods as at the Ben Nevis Observatory, 

 and is so entered in the Tables. During 1904, however, the amount was measured from 

 the half hour before to the half hour after each hour and the value put down only to 

 0*01 inch. The Fort- William Rainfall tables for 1904, therefore, are not strictly 

 comparable hour to hour with those of the Ben Nevis Observatory for the same year, 

 as these latter have the rainfall entered in the old way.
