The Committee was appointed, as in foi-mer years, for the purpose of 

 co-operating -with the Scottish Meteorological Society in making Meteoro- 

 logical Observations on Ben jSTevis. 



The hourly eye observations by night as well as by day have been made 

 uninterruptedly by Mr. Oraond and his assistants during the year at the 

 Ben Nevis Observatory ; and the continuous registrations and other 

 observations have been carried on at the Low Level Observatory at Fort 

 William with the same fulness of detail as during the previous four years. 



The Directors of the Observatories tender their cordial thanks to 

 Messrs. C. M. Stewart, B.Sc, A. D. Russell, and C. T. R. Wilson for 

 valuable assistance rendered as volunteer observers during the summer 

 months for about six weeks each, thus giving gi-eater relief to the members 

 of the regular observing staft". 



For tJie year 1S94, Table I. shows the monthly mean and extreme 

 pressures and temperatures, hours of sunshine, amounts of rainfall, number 

 of fair days and of days when the amount exceeded one inch, the number 

 of hours of bright sunshine ; and this year for tlie first time the mean 

 rainband (scale 0-8) at both Observatories, and the mean hourly velocity 

 of the wind in miles at tlie top of the mountain. The mean barometric 

 pressures at the Low Level Observatory are reduced to 32° and sea level, 

 while those at the top of the Ben are reduced to 32" only.
