Meteorological Observations on Ben Nevis. — Report of the Committee, 

 consistinc/ of Lord McLaren (Chairman), Professor A. Crum 

 Brown (Secretary), Dr. John Murray, Dr. Alexander Buchan, 

 Hon. Ralph Abercrombie, ajid Professor Copeland. (Brawn up 

 by Dr. Buchan.) 



The Committee were appointed as in former years for the purpose of co- 

 operating with the Scottish Meteorological Society in making observations 

 on Ben Nevis at the two observatories situated respectively at the top and 

 bottom of the mountain. 



During the year the hourly eye observations by night and by day 

 have been uninterruptedly made by Mr. Omond and his assistants ; and 

 the continuous registrations and other observations have been carried on 

 at the Low Level Observatory at fort William with a like fulness of 

 detail as in previous years. 



Owing to frequent storms and heavy snowfalls, which lay long and 

 deep, the climatic conditions at the top of the mountain were very severe ; 

 hut the Directors have the greatest satisfaction in reporting that the 

 health of the observers has notwithstanding been good. The Directors 

 tender their best thanks to Messrs. Charles Stewart, B.Sc, Craig, Shand, 

 Herbertson, and Rankin.
