meter tube is 0°28 of an inch. The time, at noon, is taken from a 
brass vertical gnomon, erected on the sill of the guard-house win- 
dow, facing the south. 
Dunmore East (Co. Waterford).—The tide-gauge at this station 
is erected in an angle of the pier, by which it is sheltered from the 
large waves which enter the mouth of Waterford Harbour from the 
south and south-west; it is also protected by a strong chain from 
the injuries which might be caused by the accidental rubbing of 
the large fishing-boats which frequent Dunmore Harbour. Al- 
though the water is not very deep, there is sufficient depth at 
spring tides to secure the accuracy of the observations recorded by 
the instrument. The zero of the tide-gauge is 17-34 feet below the 
bench-mark on the pier. 
The meteorological instruments are erected at the guard-house 
of the station, which is at a higher elevation than the tide-gauge ; 
the cistern of the barometer being 55:4 feet above the bench-mark. 
The diameter of the tube is 0°32 of an inch. The time at noon 
is found by means of a brass vertical gnomon erected in the window 
of the guard-house. 
West Coast Stations. 
Boncrana (Co. Donegal).—The tide-gauge was at first erected 
at Bunerana, attached to a rock near the mouth of the river, by 
means of iron stanchions; but, on inspection, the site was found 
to be wholly unsuitable. The instrument was, therefore, with the 
consent of the inspecting commander of the station, removed to 
Rathmullan, at the opposite side of Lough Swilly, where it is 
erected in a good situation, at the head of the pier. A hurricane 
house has been fixed on the pier, for the shelter of the observer. 
The meridian line is laid down to the north of the coast-guard flag- 
staff. 
The meteorological instruments are put up at the guard-house 
at Buncrana, in charge of the chief boatman ; the site is not as fa- 
vourable as could be wished. The height of the cistern of the 
barometer above high water (spring tides) is forty feet. The diame- 
ter of the tube is 0°34 of an inch. 
Kintyzecs (Co. Donegal).—Much difficulty was experienced
