Report respecting the Two Series of Hourly Meteorological 
. Observations kept at Inverness and Kingussie, at the Ex- 
pense of the British Association, from Nov. 1st, 1838, to 
Nov. 1st,1839. By Sir Davip Brewster, K.H.,F.R.S., &c. 
Havine selected Inverness and Kingussie as two suitable sta- 
tions for carrying on the two series of hourly observations with 
the thermometer and barometer, I prevailed upon the Rey. 
Mr. Rutherford, of Kingussie, and Mr. Thos. Mackenzie, 
Teacher of Raining’s School, Inverness, to undertake these 
observations. ‘The necessary instruments were made by Mr. 
Adie, of Edinburgh, under the superintendence of Prof. 
Forbes, and the observations begun on the Ist of November, 
1838, that month being the commencement of the meteorolo- 
gical year, or the first of the group of winter months. 
While these observations were in progress, I communicated 
to the Association at Birmingham a specimen of those made 
at Kingussie, with a brief notice, which is published in the 
Report of last year. I have now the satisfaction of laying be- 
fore the Association the observations themselves, forming two 
quarto volumes, a work of stupendous labour, executed, for 
the first time, by educated individuals, with the aid of properly 
instructed assistants. 
The observations made at Kingussie, and, to a certain ex- 
tent, those made at Inverness, contain ampler details of me- 
teorological phenomena than any series of hourly observations 
with which 1 am acquainted. In addition to the thermome- 
trical observations, the height of the barometer and the tem- 
perature of the mercurial column were observed every hour. 
The general character of the weather was carefully noted. 
The character and direction of the wind at every hour was 
recorded. ‘The number of hours of wind, of breeze, of calm, 
of rain, of snow, and of cloudy and clear weather were regu- 
larly marked ; and the number and nature of the Aurore Bo- 
reales were recorded and described. 
When these observations are compared with those made at 
Leith, under my superintendence, for four years, from 1824 to 
1827 inclusive, at the expense of the Royal Society of Edin- 
burgh,—with those made at Plymouth, from 1832 to 1840, at 
_ the expense of the Association, and under the able superin- 
_ tendence of Mr. Snow Harris,—and with those made at Padua, 
4 Philadelphia, and in Ceylon, we perceive very distinct traces 
of meteorological laws, of which no idea had been previously
