Meteorology records and analysis of the observatory records for September 1866 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 September 1866.
No September of the previous nine years was so favorable to health and life as the present month. The deaths were less than in any former September on record by 20 per cent, and below the average of the previous nine years by more than 33 per cent. Atmospheric pressure, though constantly oscillating, had no extreme ranges; wind movement was constant, but moderate, and the quality of the air was most pure ; electricity was abundant, and rain-fall sufficient. The month's mean was warmer than the average, with extensive daily extremes, the latter being the only phenomenon that apparently had any adverse effect upon health and life.
