March 1895 was only 46°3. Influenza, which had begun 
to develop lethal activity during the month of February, 
prevailed this month with the virulence of a plague, the 
death-rate shooting up to more than double the average, 
with an enormous mortality from diseases of the re- 
Spiratory organs, especially among the aged. Many 
children fell victims to the prevailing epidemic of measles. 
By the end of the month the health of the city was about 
normal. 
April,—Little sunshine was recorded during the first and 
last weeks, when the barometer was low, and nearly all the 
month’s rainfall was recorded. The last frost of the season 
occurred on the 14th. A warm spell occurred from the 20th 
to the 25th, when the mean temperature was 6° above the 
average. Auroras were observed on the 13th and 14th. 
The rainfall amounted to little more than half the average, 
but with this exception the meteorological elements were 
about normal. 
May.—Remarkably fine weather prevailed throughout, 
over 200 hours bright sunshine being recorded, this being 
the sunniest May since 1884. Insolation was very strong, 
the day temperatures being 4°°4 above the average, but the 
night temperatures only 2°°0. The rainfall was deficient, 
all falling between the 17th and 25th, when several thunder- 
storms were experienced. The last 5 days were phenomen- 
ally warm, the shade maxima exceeding 70° every day. 
Vivid sheet lightning was observed on the evening of the 
30th, on which day the air was very dry, the humidity, 
even at 7 P.M., being 45 per cent. There was an excess 
of northerly winds. 
June.—Although sunshine was in excess of the average, 
the precipitation was above the normal quantity, no less 
than half the rainfall being recorded on the 18th and 19th. 
Severe thunderstorms were experienced on the latter date, 
accompanied by torrents of rain. Thus between 11.7 and 
11.40 a.m., 0°53 inch of rain fell, of which 0°40 inch fell in 
21 minutes. Another thunderstorm occurred at 1.30 P.M., 
when 0°13 inch of rain and hail fell in 10 minutes. Thunder- 
storms were also recorded on the 29th and 30th. A severe
