9. Remarkable Cold in Inverness-shire on the 5th and 6th 
bf February . — A very extraordinary degree of cold was ob- 
served on Wednesday the 5th of February 1828, at the Doune, 
the seat of J. P. Grant, Esq. M. P. of Rothiemurchus. 
The following are the observations which were made with 
Fahrenheit’s thermometer j

This sudden rise of the thermometer was succeeded by a shower 
of snow. The thermometer stood at -{- 20° all the day and even- 
ing. T his depression of the thermometer is the most remark- 
able that has ever been recorded in Scotland, being a degree 
lower than the great cold of January 14. 1780, when Dr Wil- 
son of Glasgow observed the thermometer at — 14° below zero. 
On Wednesday, February 5., the thermometer was lower in 
Edinburgh than at any other time this season. On the even- 
ing of that day we observed it at -f- 28°, and in a very short time 
we saw it sink to -f- 12 1°. 
10. Temperature of Springs and Deep Wells . — The Royal 
Society of Edinburgh has received various interesting obser- 
vations on the temperature of springs and deep wells, from dif- 
ferent parts of Scotland. These observations are of very great 
interest, and ought to be made in every part of the kingdom. 
Those who are not able to keep a regular register of the ther- 
mometer, might, without any difficulty, take the temperature of 
a spring twice or thrice every month of the year, which would 
give results of great value. 
11. Mean Temperature of Cape Town. — Mr Colebrook, in 
a paper on the Climate of South Africa, published in the 
Journal of Science, No. 28. p. 241., has stated the mean tem- 
perature of Cape Town at 67°.88 Fahrenheit, and the extreme
