not accidental, Tasmaniaa oxperienco by no means confirms the English 

 aphorism. 



Solar-Intensity mean was, 9110 degrees, being + 2*84 more than the 

 average of the previous nine years, and even + '40 more than September 

 1864. The maximum temperature happened on the 26th and was 111 degiees, 

 which is higher than any ever before recorded in September. The maximum of 

 1864 was 60 degrees less. 



Terrcsitial-radiation \\a.di 9. -mevixv oi 40" 17 degrees, which is +1"98 degrees 

 above the average of the previous nine years, but — '56 of a degree less than 

 the mean of September last year. The extremes were 30 "5 degrees on the 17th, 

 49-5 on the 26th. 



Rain fell to the aggregate amount of 2*55 inches, which is + "68 of an inch 

 more than the 20 years' mean for September. It also exceeded September 1864 

 by more than one-half. At the same time it must be remembered that August, 

 Jvdy, and June were all below their res])ective averages. 17 days were recorded 

 on which more or less rain fell, being + 1 "90 above the average of the previous 

 ten years. The greatest quantity was precipitated on the 7th, — 80 of an 

 inch ; but on four other days, equally distributed as to intervals, enough fell to 

 scavenge the city streets, and drainage-channels. On the 7th snow and hail 

 were mixed with the rain as it fell in the city. Snow was abundant on Mount 

 Wellington during the whole month. 



Humidity mean, 71, notwithstanding the large rain-fall was — "Sg below the 

 20 years' average. 



Elastic-force of rapowr had a mean of 277, which is— 3 less than the 20 years' 

 standard. It ranged from minimum 182 on the morning of the 5th to maxi- 

 mum 369 on the evening of the 22nd, It was continuously high from the 

 20th to 27th and on 14th and 15th, Both were periods of excessive mortality. 



C/oucZ mean 6 "76 was -}-l "01 higher than the September average of the 20 

 years' standard. "With so high a mean of sunshine this is remarkable, and 

 indicates an unusual warmth of the solar rays. 



Ozone had a mean of 7 "99 which though -f- '04 above the mean of the preyious 

 eight y ears, is considerably less than any of the three preceding Septembers. 

 The maximum 10 (saturation) was recorded four times. The minimum was 6, 

 registered on the 20th and 22nd. 



Ekctricity was very abundant, "Nil" was not noted at any one of the 60 

 observations. Positive was registered 33 times, with a maximum tension of 

 75; and Negative 27 times, with maximum tension of 8 "5. September 

 1864 had not nearly so large an amount. No lightning or thunder was observed 

 in Hobarton. 



43 deaths occurred this month, being 3| less than the average for September 

 of the previous eight years. One half of the eight had considerably more, and 

 the other half somewhat less. Last year had six less, but a minute examination 

 of the details shows that the present month was not less healthy to the popu- 

 ation at large, but that the excess arose from the greater number of accidental 

 and violent deaths, and the greater number received into and dying in the 

 Hospital from the other districts. 



Under one year old" the number of deaths was slightly above the eisht years*
