The mean temperature was below the average from the 14th to the 24th. The coldest day (air 35°.2, damp bulb 32°.8) was the 16th. The lowest mean temperature of the damp-bulb thermometer occurred on the 17th (air 36°.2, damp bulb 30.9). Circumstances were anti-cyclonic with probably abnormally slight decrease of temperature with height. Snow-storms were reported from China to the north and east of the Colony. From Macao snow was reported, but that appears to have really con- sisted of small-sized hail, which fell for 4 hours. Neither snow nor hail were seen in Hongkong, but the tops of the hills appeared to be covered by snow or hoar-frost. Water exposed in buckets or in pools was several mornings found covered with ice about inch thick, and a few hundred feet above sea-level both the grass and branches of trees, being cooled below the temperature of the air (which did not fall below freezing point) owing to evaporation and radiation, were encased in unusually clear and transparent ice without any appearance of crystallisation. As far south as the Straits Settlements the cold was felt but in a less degree. The temperature appears not to have fallen below 70° in Singapore. At sea strong N breezes were observed during the greatest cold. The Colony was sheltered by the mainland and only light N breezes were registered till the 20th, when the wind backed to W. It veered to E on the 21st. During the coldest days the pressure was from one to two tenths of an inch of mercury above the mean. The sky was overcast but cleared on the evening of the 17th. Owing to radiation the extreme temperatures occurred after this epoch: the lowest air-temperature 32°.0 about 7 a. on the 18th, and the lowest damp-bulb temperature 27°.7 about 2.30 a. on the same day.
