the 5th, and 71°'3 on the 6th, this being the first time on 

 which each of three consecutive days had a mean tempera- 

 ture in excess of 70°. This very nearly happened in June 

 1826, when the average for the 28th was 74°-0, for the 29th 

 73°-5, and for the 30th 69°'0. The maximum readings on 

 the 4th and 5th were in excess of anything recorded in 

 September since 1838, when a value of 84°'0 was registered 

 on the 9th of the month. The nocturnal warmth from the 

 3rd to the 8th was very unusual, the mean of all the minima 

 being 60°-2. The temperature never fell below 62°'0 on the 

 3rd, 62°-6 on the 6th, and 60°-6 on the 7th. The minimum 

 value on the 6th was the fourth highest recorded in any 

 month during the last fifty-seven years, the warmest of 

 all being the night of August 4th-oth, 1890, when the lowest 

 reading was 63°'3. The unusual warmth was aggravated by 

 the great humidity, the air for several days being nearly 

 saturated, more especially at night. Taking the heat wave 

 in its various aspects, it seems to have been the most note- 

 worthy experienced since the very warm June of 1826. 



October. — This was a very mild month, the mean of the day 

 temperatures being 2°-5 above, and of the night temperatures 

 5°*1 above the average. The mean temperature of 51°'0 is 

 the highest in October since 1857. The month opened with 

 fine dry warm weather, the maximum shade temperature of 

 70°-2, recorded on the 4th, being the highest in October 

 since 1845. The long spell of dry weather broke up on the 

 15th of the month, the rainfall for the second half being 

 three and a half inches. Sunshine was below the average, 

 and rainfall 54 per cent, above the mean. Dense fogs were 

 recorded on the 5th and 29th. 



November. — November opened with warm and wet weather, 

 an inch and a half of rain being recorded on the first 

 three days of the month. Temperature was very high on the 

 2nd, a maximum of 6r-0 being registered, this being the 

 highest in November since 1881, and only exceeded in three 

 of the last fifty- eight Novembers. Mean temperature was 

 1°'6 above, and rainfall 56 per cent, in excess of the average. 

 Sunshine was only half the mean, and there was a dense fog 

 daily from 9th to 12th. Towards the close of the month a
