being from the 13th to the 19th. Snow fell on the 19th and 
20th. An aurora was observed on the 7th, the beams being 
of a whitish colour. 
June.—The first three weeks of June were characterised 
by a temperature under the average, with dull weather; but 
the last week was sunny and warm, the maximum tempera- 
ture recorded on the 26th being 74°-1. Winds were rather 
variable, being chiefly from the east during the first half, but 
from the westward during the second half of the month. 
The rainfall was about half an inch above the average, 
nearly all falling on four wet days. Thus on the 4th and 
5th there fell 1:21 inch in 16 hours, while on the 10th and 
11th 1 inch was registered. Thunderstorms occurred on the 
1st and 10th. A fine display of illuminated night clouds 
was seen on the evening of the 24th. 
July.—The month opened with warm weather, the maxi- 
mum temperature on the 1st being 73°°6, and on the 6th 77°'5. 
Exceedingly unsettled weather prevailed, thunderstorms being 
frequent. No: warm weather occurred after the first week, 
although there were many days that felt exceedingly close, 
owing to the abundance of water-vapour. Jainfall was 
slightly below the average, in spite of torrential showers on 
the 2nd, 6th, 15th, 20th, and 21st, when thunderstorms were 
experienced. The weather during the last week was very 
foggy, especially in the mornings, the afternoons being on 
the whole sunny. This is well shown from the records of 
sunshine from the 25th to the 51st, during which period the 
sun shone in the aggregate on only 3} hours before noon, 
but on 22 hours during the afternoon. 
August.—Cool and wet weather were the leading features 
of the meteorology of this month. Not a single warm day 
was recorded, the absolute maximum of 68° registered on 
the 8th being the lowest since 1865, when the same low 
maximum was observed. Westerly winds blew during the 
first three weeks, and were sometimes rather strong in force. 
Dull weather predominated. Thunderstorms occurred on 
the 9th and 17th. 
September.—Very dry weather was experienced throughout, 
no rain whatever falling from the 6th to the 20th inclusive,
