proTailing catarrh, notwithstanding the popular idea of taking cold from such a 

 cause, for this disease did not exist l;\st year, and tlie deatlis from diseases of 

 the respiratory organs were loss than usual. The greatest range on any day of 

 the present montli was 30 degrees on the 14th, and the smallest range was 8 on 

 the ,SOth ; last year the extremes were only 28 and 15. 



The Solar-thcrmomdcr had a mean of 75-87 degrees, which is + .3-9 above 

 the average of the previous ten years, but — 3*11 degrees less than June 

 18G5 had. The maximum was 93 on the 7th, the minimum 56 on the IGth. 

 In 1865 the extreines were 94 and 59. 



Tcrrcatial-RadiationmeaM, was .36 '52 degrees being — 'll of a degree less 

 than tlie average of the previous ten years, but + "87 of a degree more than 

 1865 had. The extremes were 51-5 on the 5th and 28.5 on the 13th and 22ud. 

 The maximum being 4 degrees more than in 1865, but the minimum the same. 



Rain-fall, in the aggregate, amounted to 1 *86 inches, being - '03 only below 

 the 20 years' mean, and just the same more than the mean of the last 25 

 years. 1865 had not so much by .m of an inch. It fell on 12 days, being+ -36 

 above the average of the previous 11 years. It was pretty equally distributed 

 through the mouth. The largest deposit '75 of an inch, took place on the Hh, 

 and thoroughly scoured the drainage channels ; '24 of an inch fell on the 17th, 

 and made the channels run briskly ; on the 3rd there was guaged "22 of an inch 

 which cleansed the surface drains. Snow appeared on Mount Wellington every 

 day during the month except the 7th. On the 9fh all the low hills about the 

 city were mantled with snow, and again on the 27th. 



Spontaneous evaporation was considerably more than rainfall as might be 

 expected from the unusually windy character of tl.e month. The amount was 

 2 '22 inches, being neai-ly an inch more than in 1865. 



Elastic- force of vapor had a mean of 266, which is —8 less than the 20 years' 

 average ; the range was from 160 minimum on the 22nd, to 403 maximum on 

 the 15th and 18th. 



Humidity mean 77, was the same as in 1865, but— 6^ less than the 20 years' 

 average. 



_ C/oM(/ mean was 5 "52, or almost identical with the 20 years' average, differ- 

 ing only by an excess above it of + -0.3. 



Ozone mean 7"05 was + "51 above the average of the previous nine years, 

 though~1.181ess than 1865 had. The maximum was 10 (saturation) on the 

 9th. The minimum was 5 several times between the 12th and 19th, which 

 had altogether an average of one degree less than that of the whole month. 

 This was the least fatal period of the month. 



Electricity, positive had not a single record, which I think is without 

 pai-allel. June, 1865, had 1 8. There were 53 negatives, with maximum 

 tension of 4-5, and minimum of-«-05. " Nil" was registered 7 times, 5 of 

 them recorded on the 15th, 16th, and 17th. On the first day calm was registered 

 at every observation, on the second, twice out of the three, but the last day 

 had strong winds. 



48 deaths for the present month is + 2 5-9 above the June average of the 

 previous nine years. Three of the nine had a gi-eater number, two exactly 

 the same, and four less. 



Under 1 year old " the deaths were little more than half of the June
