unsettled, although there were only two days without 

 bright sunshine. Pressure throughout the month continued 

 low, there being an almost complete absence of anti-cyclonic 

 conditions. During the first eleven days there was a con- 

 tinuance of the abnormal warmth of August; thereafter, 

 until the 20th, conditions were about normal, but the last 

 ten days of the month were decidedly cold for the season. 

 A sharp thunderstorm was experienced on the 29th with 

 heavy rain and hail, and the last day of the month proved 

 the wettest of the whole year, with a rainfall of 1*38 inch 

 in the 24 hours. 



October. — October was characterised by high temperature 

 and pressure, accompanied by a rainfall only half the 

 average. Sunshine was normal, and mean relative humidity 

 decidedly below the average. A dry, warm, and sunny 

 period prevailed from the 13th to the 24th, during which 

 temperature rose to the unusual height of 67°'4 on the 19th, 

 this value being 15° in excess of the normal for the season. 

 There was a south-west gale with strong squalls on the 29th, 

 and a thunderstorm with heavy rain and hail at 7.35 p.m. 

 on the 30th. Showers of hail also fell on the 13th. 



Novemler. — The outstanding feature of the weather of 

 November was the extraordinary mildness of the air, the 

 mean temperature being 47°'4, or 6°-5 above the average. 

 This is absolutely the highest mean temperature on record 

 for November during the last 135 years, the next highest 

 occurring in 1818, when the mean was 46°-7. An examina- 

 tion of the daily temperature observations shows that the 

 maximum exceeded 50° on twenty-three days, while on no 

 occasion was frost registered in the screen four feet above 

 grass. The month opened with very stormy weather, the 

 rainfall on the 2nd slightly exceeding an inch. Unsettled 

 conditions continued till the middle of the month, the second 

 half of which was on the whole fair and dry, with a high 

 barometer. No fogs were experienced, but bright sunshine 

 was below the normal. As regards the other elements, 

 pressure and rainfall were above the average. Relative 

 humidity was 5 per cent, below the mean. The winds of 

 the month blew almost wholly from the west and south-west.
