Meteorology records and analysis of the observatory records for May 1865 in conjunction with those of births and deaths

Meteorological records recorded at the Observatory, Hobart Town.Includes the leafing, flowering, and fruiting of a few standard plants in the Royal Society's Gardens during the month of May, 1865.
The fluctuations in atmospheric pressure, with the frequent and extreme variations in temperature, this month, had an extensively fatal influence on aged and diseased persons, and, together with the unusually numerous accidental deaths, caused a total mortality slightly beyond the average of the previous eight years, though, still, considerably fewer than May, 1864, had.
On the other hand, the pure state of the air, consequent upon its free movement the moderate rain-falls, and abundance of electricity, preserved the community from Zymotic diseases; and infantile deaths were not half the number that May, 1864, had.
