annual range of 74 8 deg. A maximum temperature of 81 deg. 

 was also recorded on the loth August, but these were the only 

 instances in which a maximum of 80 deg. and above was reached. 

 In July the highest was 76 deg., and in June 77-5 deg. There 

 was thus a smaller number than usual of very warm days. There 

 were 9 days in June and 14 in July with temperatures of 70 deg. 

 and above in the shade, but only 5 in August in addition to the 

 2 at 81 deg. The warmest month was July, which had a mean 

 temperature of 61-6 deg., June was next with 58'9 deg., and then 

 August with 57 '6 deg. July was a degree and a half above ave- 

 rage, June about average, and August nearly one degree below. 

 The coldest month of the year was February, which had a mean 

 temperature of only 34 deg., being fully four deg. below the 

 mean for that month. February was in fact a month of unusual 

 wintry severity. Not only was the lowest temperature of the 

 year recorded in it, but there were 18 nights of more or less 

 severe frost, with an aggregate of no less than 149 deg. below 

 the freezing point, and a severe snow storm, as previously noted, 

 with a strong easterly and south-easterly gale, which did much 

 damage. The other winter months were comparatively mild. 

 January, with a mean temperature of 39-6 deg.,had several nights 

 of frost, but none of them severe. March was cold, with some 

 sharp frosts after the middle of the month, and a mean temperature 

 of 39 deg., nearly 2 deg. below the mean. But November and 

 December were both exceedingly mild, the former having a tem- 

 perature of 4 deg. and the latter of G deg. above the average. 

 There were six months in which the temperature was above the 

 mean, viz., January, July, September, October, November, and 

 December, the excesses in these months amounting to 14-5 deg. 

 The deficiencies in the other months amounted to 8-9 deg. The 

 mean annual temperature comes out at 48 deg., which is about 

 half a degree above the average of 13 years. I may mention that 

 48 deg, is given as the mean annual tempei-ature of Dumfries in 

 the isothermal maps which give the lines of equal temperature. 

 If any one has a good atlas, such as Bartholomew's Pocket Atlas 

 of Scotland, and will look at the isothermal map which it contains. 

 he will sei5 that the line of 48 deg. starts from somewhere about 

 Newcastle, then passes in a north-westerly direction to Dumfries, 

 then west from Dumfries through Wigtown, then in a northerly 

 direction towards Arran and the Isle of Bute, then easterly
