maxima, or high-day temperature records, was 64 -50 degrees, being — 6 

 degrees "below that in November 1865. The minimum temperature 

 recorded was 38 degrees, which is one degree less than I860 had, and from 

 3 to 8 less than any year since 1854. The mean of all the minima or low- 

 night temperature records, was 46-13 degrees, being — 2-64 less than 1865 

 had. 



The -niQPin Daily-range of Temperature, 18*97 degrees, is +-13 above the 

 20 years' mean, though — 374 degrees less than 1865 had. The greatest 

 range on any day was 36 degrees on the 4th and 6th ; and the smallest 

 range on any day was 8 degrees on the 10th. Only 1865, 1864, 1846, 1843 

 had a greater range on any day in the month, than that of the present 

 month. 



Solar -intensity mean, 101-23 is, — "58 less than the average of the pre- 

 vious ten years, and — 6-50 below last year's mean, the present month 

 having been much more cloudy. The maximum was 121 on the 4th, the 

 minimum 61 on the 10th. Last year the extremes were 129 and 71 

 degrees. 



Terrestrial-radiationhsidL the mean of,44- 58 degrees, being — 1-91 degrees 

 less than the average of the previous ten years, and — 1*90 below the 

 mean of November 1865. The extremes were : — Maximum, 50-5, on the 

 7th ; minimum 35-5 on the 8th. Last year the corresponding records 

 were respectively, 51 and 39 degrees. 



Rain-fall in. the aggregate amounted to 3-54 inches, being +-78 of an 

 inch above the 20 years average for November, and +1*51 more than 1865 

 had. On the average of the last 25 years November is much the wettest 

 month of the twelve. Eight out of the 25 years, however, had heavier 

 rain-falls than the present month. Four of them were consecutive : — 1848, 

 1849, 1850, 1851. In 1849 the maximum of the 25 years, 8-94 inches, was 

 recorded. Eain fell on one half of the days of the month, being +2-18 

 more than the average of the previous eleven years, and +3-00 more than 

 1865 had. On the ten days, 9th to 18th, rain fell every day, and very 

 heavily on the 10th, 11th, 12th, 13th, their total being 2-73 inches and 

 causing a partial flood. This thorough cleanings of the rivulet and the 

 other sewer channels of the city, was an admirable preparatory preser- 

 vative for the health of the community during the warm months of summer. 

 Snow was seen on Mount Wellington every day of the month, except 

 from 3rd to 12th, on the latter day the mountain was copiously mantled 

 with a fresh deposit and a patch of it remained unmelted on the last day 

 of the month. 



Spontaneous Evaporation only slightly exceeded precipitation, being 3-71 

 inches. 1865 had 5-46 inches. 



Sumidity mean, 71, was +5 more than last year, but exactly the same 

 as the mean of the 20 years' standard. 



Elastic-force of Vapor had the mean of 321, which is — 6 less than the 

 20 years' average, and — 11 less than 1865 had. 



Clo^ldmQ^i^l, 6*68, was + '59 more than the 20 years' mean and + 1-09 

 above the 1865 mean. 



Ozone mean, 7 '92, was + '36 above the mean of the previous 9 years, 

 though — -54 less than 1865 had. No doubt the greater aerial movement in 

 1865 accoTonts for the preponderance. The point of saturation (10) was 

 recorded three times in the present month, and the minimum noted was 

 6*5. So much ozone, low and variable temperature, and keen southerly 

 winds, caused inflammatory afi'ections of the respiratory organs — and the 

 deaths in this class of diseases were above the average. On the other 

 hand, the same weather was quite antagonistic to the diseases of the 

 miasmatic order in the Zjmi otic class. 



EUctricity records were: — 25 positive with tension ranging from 7 to 

 2-5; Negative 34, with 7*5 to 1*0 tension. Only one Nil. Thunder and 

 lightning accompanied a rain storm on the afternoon of the 16th.
