The only preliminary remark 1 have to make before submit- 

 ting this annual report of meteorological observations at Dumfries 

 for the past year is that the instruments used were inspected by 

 Dr Buchan, the secretary of the Scottish Meteorological Society, 

 on the 27th August last, and, on being compared with his standard 

 instruments, wei'e found to retain their former accuracy, the varia- 

 tions in the case of the thermometer not being more than two- 

 tenths of a degree, and in the case of the barometer of rather less 

 than two-hundredths of an inch, which practically may be 

 regarded as negligible quantities. 



Baeometer. — Beginning with the barometrical pressure, 

 the following are the leading facts : — Barometer — Highest on 

 23rd May, 30-660 in. ; lowest on 25th December, 28-600 in. ; 

 annual range, 2-060 in. Mean pressure for the year (reduced to 

 32 deg. and sea level), 29-925 in. This is slightly above the 

 average of the last fifteen years, which was 29-904 in. There 

 were six months in which the mean pressure exceeded 30 in., viz., 

 February, May, June, July, August, and November. The lowest 

 monthly mean occurred in December, amounting to no more than 

 29-515 in., and this was the month in which the most changeable 

 and unsettled weather was recorded. It had the absolute mini- 

 mum of barometrical pressure for the year, viz., 28*600 in. on the 

 25th, and the readings of the 23rd, 24th, and 26th were almost
