below freezing all day : there was very slight variation in the baro- 
metric pressure, which oscillated between 29.8 and 29.9. A heavy 
fall of snow occurred early on the 14th: it was 3 in. deep at 9 a.m., 
but a rapid thaw set in soon after, and at 9 a.m. the 15th, the 
temperature was 45.0 — 12 degrees higher than the previous day. 
The last fortnight was much milder, averaging 45.7, but the sky 
was mostly overcast ; frequent slight showers of rain, and strong 
W. and S. W. winds with considerable oscillation in the barometric 
pressure. The mean barometric pressure for February averaged 
unusually low : it only rose above 30 in. on the first three days 
and on the 24th. The rainfall was 1.28 in. in excess of the 
average, and the largest amount recorded in February since I860. 
March. 
This month Avas remarkable for the unusually low barometric 
pressure and heavy S.W. and W. gales. The mean barometric 
pressure was 4-10ths of an in. below the usual average ; and in no 
month during the last six years have the readings averaged so Ioav, 
nor has the Avind averaged so high a velocity. Mr. Glaisher states 
that at GreenAvich during the last thirty-five years, the mean baro- 
metric pressure has never been so Ioav in March as in this year. 
The temperature during the first fifteen days Avas generally slightly 
above the average, but the days were very cloudy and frequent 
shoAvers of rain occurred. The barometer oscillated slightly at 
about 29.6 in. during the first Aveek Avith strong S.W. and W. 
AA r inds; then fell rapidly on the 8th from 29.629 at 9 a.m. to 28.996 
at 9 p.m., and further to 28.645 at 9 p.m. the 9th, Avhen a daily 
velocity of 331 miles Avas registered : the readings remained beloAv 
29 in. until the evening of the 11th, when they reached 29.195. 
Another quick fall to 28.730 at 3 p.m. the 12th, Avas folloAved by 
a rapid rise to 29.542 at 9 a.m. the 13th ; after which the pressure 
fell to 29.091 on the 15th, Avhen a strong W.S.W. gale of 436 
miles was recorded. A strong W.N.W. and N.W. gale of 350 
and 406 miles occurred on the 17th and 18th. From the 16th of 
March to the 27tli (except the 24th) the weather Avas very cold, 
Avith frequent snow storms, and frosts nearly every night ; on the 
1 8th the highest temperature Avas only 5 degrees above freezing, 
and Avas folloAved by a frost of 6 degrees in the night. Early on
