SUPPLEMENT TO THE HONGKONG GOVT GAZETTE OF 17TH JAN., 1885. 57
. Be the 1st January the main building was so far finished, that I could take up my residence and start tri-diurnal meteorological observations. It is a rectangular block, 83 feet long and 45 (not including the transit room). The upper floor is devoted to my quarters. The ground comprises 1 rooms, each 20 feet long, 16 feet wide and 14 feet high, and 2 small rooms behind In the entrance hall are placed the telegraphic apparatus, through which the Observatory is with the Police Stations in Kaulung, and through them with the Central Police Station in To the right is my office, where the library is placed, contained in glazed teak-wood clock room, behind which is the galvanic battery room, is to the right of this. From the door lends into the transit room. To the left of the entrance hall is the computing room, h is the instrument room, where the barometers, the barograph and the thermograph are in which is the photographic laboratory.-Every part of the two last rooms, including or and furniture, is painted dark red, and there are only a few panes of double red glass in

hetic hut is 17 feet long, 13 feet broad, and the roof rises 11 feet high. It is made white outside and inside. Bamboo chips instead of nails were used in its construction the furniture. It has double doors, respectively louvered and glazed, to the north and windows on cach side as well as two frosted glass windows in the roof, which throw verniers. On top of massive teak-wood blocks sunk 3 feet in the ground and rising 4 the floor are placed the unifilar magnetometer and the dip-circle. The former is placed the latter, and it is therefore convenient to observe the pole-star reflected from the speculum ing the door. The sun and stars near the prime vertical can be observed through the windows Bir side. The hut is very comfortable but is placed at an inconvenient distance from the main A broad road connects the two buildings and includes a bridge across the gap between the The magnetic observations are printed in my report of the 15th December (Appendix I to the ming * Observations and Researches in 1884") and it is therefore unnecessary to make further
nce to these observations.
12. As the time-service has not yet been started and as no astronomical observations have been hol, it would appear most proper to defer the description of the astronomical instruments, some hich have not yet been erected.
1. The tri-diurnal meteorological observations, that were started at 10 a. on the 1st January, tinued up to the end of the year. In January and February observations were made at 10 a. 110 p. as printed in the Weather Reports for those months. In March and April they were 10a. 1 p. 4p. 7.45 p. and 10 p. From the 1st May till the end of the year they were made 1p. p. and 10p. From the 1st April till the 1st October the standard barometer was wl also at 1a. Phenomena occurring at other hours including clouds of the cirrus type nofully noted.
T.
The observations made at 7 45" p. (7 0 a. Washington Mean Time) the epoch adopted rational Simultaneous Meteorological Observations were transmitted to the Chief Signal . S. A.. Washington, D. C. They embrace the height of the barometer reduced to 32° ted to sea level, dry and damp bulb thermometers, relative humidity, direction and vélo- wind, and also observations on rain, clouds and state of the weather. Since the 1st May latter observations were actually made at the time, it being preferred to read off the other from the curves described by the self recording instruments below described. 15. From the 1st January a new series of meteorological observations made according to my for making Meteorological Observations" were commenced at different points in the A: Victoria Peak observations of the barometer, dry and damp bulb thermometers, direction
f the wind, clouds, sea and state of the weather are made et a. 10 a. 1p. 4p.
and 10 p. Fr 10a, 4p. and 10 p. are published in the monthly reports. At the latter hour the self- theria meters including black bulb and grass minimum are read. The rainfall is collected One of them is an old roof-gauge. The other is placed one foot above the ground. -alts from the latter are published."
P.
servations being made at so high a level are of considerable importance, and it is to that the authorities have not yet made arrangements for having observations made also at sure of self-recording instruments the observations are not complete without the 4a. It would moreover be desirable at some future time to erect a self-recording anemometer Smilar to the one on top of the Observatory. The comparison of the two records ly reveal certain most important features connected with the wind prevalent at different ive sea level, which would deepen our insight into the law of storms in the China Sea. At Cape d'Aguilar observations of thermometers, wind, clouds, sea-surface and weather are 10a. 4p. and 10 p. as published in the monthly reports, but as these observations are accuracy, their publication with the exception of the state of the sea-surface, will be dis- 1 next year.
