September 3-17. The mean temperature of these fifteen days was 

 63° - 6 or 8° - 5 in excess of the normal. From the 4th to the 6th the 

 maximum temperatures were over 80°, being 82°, 82° - 8, and 80°, while 

 the minima were 59°, 57°'6, and 62° - 6. The mean temperature was 

 70°-5 on the 4th, 70°"2 on the 5th, and 71°*3 on the 6th, this being the 

 only occasion in eighty years on which each of three consecutive days had 

 a mean temperature in excess of 70°. The nocturnal warmth from the 

 3rd to the 8th was very unusual, the mean of all the minima being 60° '2 ; 

 the air was unusually damp, which made the heat very oppressive. 



February 12 and 23. 



February 26. Rain fell, with the temperature below the freezing point, 

 covering trees, telegraph wires, etc. with a transparent sheet of hard ice. 



March 19-25. The mean temperature for the week was 32° - 6, or 8°'6 

 below the normal. 



March 21. 



May 24 to June 17. During these twenty-five days no rain fell, the 

 drought being the most severe since the summer of 1869. 



January 19. Thunderstorm, with heavy rain and hail, at 5.45 p.m. ; a 

 bright aurora was seen at 615 p.m. 



February 15. South-east gale, with heavy snowdrift. 



February 20. Heavy snow during night ; eight inches fell. 



May 28. Partial solar eclipse, observed under fair conditions.

 N.E. wind. 



August 23. Severe thunderstorm, with very heavy rain and hail, from 

 5.30 to 6.20 p.m., 0'62 inch falling in eighteen minutes. A well-defined 

 waterspout was seen at Duddingston about 6 p.m., remaining visible for 

 full}' ten minutes, when the lower portion slowly melted away, the upper part 

 being absorbed into the clouds. It presented much the same appearance 

 as the one seen at Edinburgh on May 14, 1826, described in the Edin. 

 Jour, of Science, vol. ix. p. 131, a graphic representation of which is 

 shown in plate ii. appended to that volume. 



September 2. Brilliant meteor seen at 6.55 p.m. in south, of a blue 

 colour. Travelled straight down. 



December 20-21. Severe S.W. gale. Anemometer at Blackford Hill 

 recorded a mean velocity of 60 miles per hour, rising to 93 miles in the 

 hour ending midnight of 20th. Many trees blown down in Edinburgh 

 and vicinity. 



Autumn very wet, the rainfall in the Newington district in October 

 being 4"87 inches, in November 5 - 42 inches, and in December 4*43 inches, 

 a total of 1472 inches for the three months, or 96 per cent, above the 

 average. October was the wettest since 1864, and November the wettest 

 since 1772.
