The Components of the Wind, and its Mean Velocity, are not perfect 

 for this month, the Anemometer having been dismounted from its old 

 position on the 8th, was repaired and mounted on the New Tower of 

 the Observatory on the 12th, consequently the results do not include 

 those quantities from the 8th to the 12th inclusive. The quantity of 

 Rain which fell during the month has been 1-028 inch above the aver- 

 age, and the number of days on which Rain fell exceeds that recorded 

 for any other June of the series. The Mean Temperature of this month 

 has been 1°.5 below the average of the last 16 years, the first three 

 weeks having been very cold, whilst the last week was excessively 

 warm. The 29th was the warmest day in any June on the records 

 of the Observatory.
