the side of the pier, close to the Ordnance bench-mark, and near 
the guard-house; it is well sheltered, and in deep water. The 
zero of the tide-gauge is 19°80 feet below the Ordnance bench-mark. 
Themeteorological instruments are likewise favourably placed: the 
barometer in the guard-house, and the thermometers and rain-gauge 
in an inclosed yard connected with it. The meridian line is traced 
on the sill of a window in the guard-house. The height of the 
cistern of the barometer was not measured; it is between 3 and 4 
feet above the bench-mark. The diameter of the tube is 0°30 of an 
inch. 
KitLouca (Co. Down).—Lighthouse, St. John’s Point.—This 
is a meteorological station only, and is well circumstanced for 
such observations. The barometer is put up in the hall of the 
light-keeper’s dwelling; the other meteorological instruments are 
well placed in a garden attached to it. The meridian-line is traced 
on the flagging, at the south side of the house, the shadow being 
given by a vertical iron rail. The cistern of the barometer is 7°8 
feet above the base of the light-house tower; the diameter of the 
tube is 0°28 inch. 
Krnestown Harzour (Co. Dublin).—This is a station for tidal 
observations only. The tide-gauge is erected in the angle at the 
inner side of the new harbour. This locality is very favourable, as 
the water is deep, and the case is protected by the pier from the 
waves which enter the outer harbour from the north-east. The time 
at this station is taken from the clock of the Dublin and Kingstown 
Railway. 
Courtown Hargour (Co. Wexford).—The tide-gauge at Cour- 
town Harbour is erected beside the wooden pier, which is now used 
for the unlading of vessels, in consequence of the filling up of the 
harbour originally built. The situation of the gauge is very 
much exposed ; but as the station was considered by the Committee 
to be important, it was determined to attempt making the observa- 
tions with the gauge lashed to the pier. - Hitherto the observa- 
tions have been but seldom interrupted by the violence of the sea. 
The barometer is erected in the guard-house belonging to the sta- 
tion ; the thermometers and rain-gauge in the garden attached to it, 
and are in charge of the chief boatman. The diameter of the baro-
