The change, however, did not take place until the 16th, and the 
temperature rose each day for the next four days, the mean being 
on 16th 44°-3, 17th 49°*1, 18th 51°-4, 19th 55°‘4, and 20th 56°*9. 
During this period the maximum rose more than 20°, hut the mini¬ 
mum varied very little, giving a range on 16th of 11°*6 and on 
20 th of 33°*8. Min. below 42° on 25 days, below 32° on 3 ; 
max. above 52° on 16, above 62° on 8. Northerly winds chiefly 
prevailed during the colder period and southerly during the warmer 
period. Thunder was heard and hail fell on several days. 
May. —Very cold, rather dull, with a rather dry atmosphere of 
rather low pressure, and with a considerable amount of rain falling 
on a great number of days. Snow fell on 8th after an interval of 
46 days without. Eain fell every day to 8th, except on 3rd; and 
again, after an interval of five days without, every day from 14th 
to 25th, except on 24th. The last 6 days were warmer than the 
rest of the month, having a mean of 57°*2, being 7°*8 above the 
mean of the month. Min. below 42° on 18 days, below 32° on 1 
(8th, when snow fell); max. above 62° on 6 (26th to 31st). It is 
unusual to have frost and snow so late in the year as the 8th of 
May. The prevailing direction of the wind was from W. through 
N.W. to N. On the day of maximum rain, 21st, with a fall of 
0-73 in., there was a thunderstorm at about 3 p.m. with heavy hail. 
Thunder was heard and hail fell on several other days. 
June. —Eather warm, very bright, with a dry atmosphere of 
average pressure, and with a small amount of rain. The rainfall 
was very unequally distributed, the five days from 5th to 9th having 
an inch and a half, leaving only 0 , 42 in. for the rest of the month. 
No rain fell from 10th to 15th nor from 25th to July 7th. The 
range of temperature was very great, the mean daily range being 
20°*0, and there having been six days with a range exceeding 30° 
(2nd, 3rd, 4th, 12th, 14th, and 18th). There were two very low 
minima (for June), on 11th, 37°*9, and 18th, 39°'7. On the 
former date a ground frost occurred. Min. temp, below 52° on 
21 days, below 42° on 2 (2nd and 11th); max. above 62° on 28, 
above 72° on 9, above 82° on 1 (4th). N.E. and S.W. winds pre¬ 
vailed, but not to any great extent. 
July. —"Warm, bright, with a very dry atmosphere of consider¬ 
able pressure, and with an exceedingly small fall of rain on a very 
small number of days. The total amount of rain recorded for the 
month (less than one-third of an inch) is all that fell from the 
25th of June to the 3rd of August, inclusive, a period of 40 days; 
from the 17th of June to the 5th of August, 50 days, only 0-60 in. 
fell; and from the 9th of June to the 1st of September, 85 days, 
only 1-85 in., considerably less than half the fall of September. 
Three days (25th to 27th) were very hot and dry.
