similarity is also striking in regard to the lowest reading, On 
the 18th January it was at 16°, or 16° of frost, whilst 18°, or 14° 
of frost, was the lowest for 1896, occurring on 23rd January and 
23rd December. There were eight days on which the thermo- 
meter did not rise above the freezing point. In the previous 
year this only happened five times. January was the coldest 
month of the year, there being twenty days on which frost 
was registered, the amount (143°) being about double that of any 
other month. The warmest month was August, with a mean 
temperature of 59°, although July closely approached it with 58°. 
In 1896 June was the warmest month, with a mean temperature 
of 57°. The hottest day was the 16th July, when the thermometer 
rose to 78° in shade. A similar temperature was recorded for 
1896. In that year the 16th June was the hottest day. The 
maximum thermometer was at or above 70° on five days in June, 
twelve days in July, and ten days in August, or twenty-seven 
times in all; whereas in 1896 it was only sixteen times, these 
occurring in May, June, and July.
