Report respecting the tivo series of Hourly Meteorological Ob- 

 servations kept in Scotland, at the expense of the British 

 Association. By Sir David Brewster, K.H. LL.D. 

 F.R.S. L. & E. 



Having fixed upon Inverness and Kingussie as two suitable 

 stations for carrying on the two series of hourly observa- 

 tions, which I undertook to establish and superintend for the 

 British Association, I was fortunate in being able to prevail 

 upon the Rev. Mr. Rutherford of Kingussie, and Mr. Thomas 

 Mackenzie, teacher of Raining's school, Inverness, to undertake 

 these observations. The instruments which were necessary for 

 this purpose were made by Mr. Adie of Edinburgh, under the su- 

 perintendence of Prof. Forbes, and the observations commenced 

 on the 1st of November, 1838, the beginning of the Meteorolo- 

 gical year, or the first of the group of winter months. I directed 

 the two observers to pay particular attention to the aurorce 

 boreales, and to record every phaenomenon of this nature ; and 

 I have no doubt, from the lists already sent me, that this class 

 of observations will be the most complete and valuable that 

 has ever been made in Scotland. 



I annex a specimen of the observations made at Kingussie 

 at the time of the great depression of the barometer on the 

 29th November, 1838, which will exhibit the nature and value 

 of the register. 



As it is of the greatest importance to obtain the true curve 

 of the daily variation of temperature and pressure at the two 

 stations of Inverness and Kingussie, the last of which places 

 is between 700 and 800 feet above the level of the sea, I 

 earnestly hope that the Association will permit these observa- 

 tions to be carried on for at least another year.
