for June. Since 1864 only one milder week has occurred in- 
October, viz., that ending the 12th October 1878, when the 
mean temperature was 56°. The wind rose to the force of 
a gale on the 24th, and was succeeded on the following day 
by a heavy rainfall. 
November.—Pressure was low at the beginning of the 
month, but an anti-cyclone advanced on the 6th, readings 
exceeding 30°5 inches being registered from the 8th to the 
12th. Very sunless weather prevailed from the 7th to the 20th, 
only 5 hours’ sunshine being recorded. Light airs prevailed 
till the 16th, when a sharp northerly gale blew, accompanied 
by the lowest barometric reading of the year, pressure falling 
to 28°51 inches. In the 24 hours ending 9 a.m. of the 17th 
pressure fell 1:24 inch, a rise of 0°97 inch taking place in 
the 12 hours ending 9 A.M. of the 18th. The second half 
of the month was stormy, with occasional snow showers, 
interspersed with brief outbursts of spring-like warmth. 
These rapid alternations of heat and cold exerted a pre- 
judicial influence on the health of the community, as evinced 
by a marked rise in the death-rate taking place con- 
currently with the above protean conditions. 
December.—The month opened with cold weather, the 
maximum on the Ist being 33°'5.. After the 3rd very mild 
weather prevailed, with one slight interruption, till the end 
of the year. Storms were frequent, that of the 8th being 
the most severe—the anemometer recording a mean velocity 
of 43°5 miles per hour for the 10 hours ending 6 P.M. Sun- 
shine was about the average, there being no spell either 
of sunny or sunless conditions. ain or snow fell every day 
from the 4th to the 14th. <A well-marked anti-cyclonic 
period set in on the 26th, the barometer rising on the 29th 
to 30°64 inches. This was the mildest December since 1865, 
ON THE WARM SPRING AND SUMMER OF 1893. 
A few remarks summarising the more salient features 
of the unprecedented warmth of the spring and summer 
may not be out of place. We have, for the purpose of com- 
parison, tables of mean monthly temperatures taken at 
Edinburgh since 1764 to the present time, 130 years in all.
