June. — After the 28th of May the pressure of the atmosphere 

 increased slightly, decreasing again to 29-395 ins. at 9 a.m. on the 

 1st of June, the lowest pressure during the month. The mercury 

 then rose rapidly, standing at 29'764 ins. at 9 p.m. on the same

 the 22nd (29-577 ins. at 9 p.m.). The highest reading was 30-265 

 ins. at 9 a.m. on the 28th. The unusually high temperature of

 are the readings of the maximum and minimum thermometers for 

 three days at each of these warm periods. 



The maximum was above 70° on seventeen days and above 74° on 

 ten. The direction of the wind was very variable, not being the 

 same for any three days together throughout the month ; and, as 

 shown in the table, it was pretty evenly divided over the different 

 points of the compass. Rain fell on four days at the beginning of 

 the month and on four days towards the end. There was none 

 for the fourteen days from the 7th to the 20th inclusive — an 

 unusually long dry period. There was a thunderstorm on the 

 night of the 4th.

 greater part of the month, the only warm periods (with a maximum 

 exceeding 70°) being from the 10th to the 13th, mean of the 

 maximum 71°-9, and from the 29th to the 31st, mean of the 

 maximum 79°-4, the meati temperature of these periods being 

 respectively 63°-8 and 65°-6. The maximum only exceeded 80° 

 on the last day of the month. It exceeded 70° on eight days. 

 Atmospheric pressure continued high (from June) for the first 

 twelve days, the mercury, after a slight fall, reaching its highest 

 point, 30-322 ins., at 9 am on the 9th, after which it fell to 

 29-218 ins. at 9 a.m. on the 15th, rising again towards the end of 

 the month and nearly again reaching its highest point on the 30th. 

 The wind maintained a westerly or south-westerly direction almost 

 throughout the month, inclining a little towards I^.W. for the first 

 few days, and towards S. between the 14th and 23rd. The rainfall 

 was pretty evenly distributed over the month. Tlie maximum of 

 the 14th was nearly equalled on the 16th, when 0-64 in. of rain 

 fell. There were thunderstorms on the 3rd, 5th, 6th, and 7th, 

 and hail fell on the evening of the 3rd.
