spring tides. So far as position is concerned, this is one of the 
most important stations on the west coast. The time at noon is 
found from a brass vertical gnomon, erected in the garden of the 
chief boatman’s house. 
No meteorological observations are taken at this station. 
Kitrvusu (Co. Clare).—The importance of having as many tidal 
stations as possible on the west coast, induced the Committee of Sci- 
ence to undertake the erection of a tide-gauge at Kilrush, although, 
from its being so far up the Shannon, the station was not as valuable as 
could be wished. The only place in which the gauge could be erected 
was at the extremity of the stone pier, facing the river, and conse- 
quently exposed to violent gales from the south-west. During the 
first few weeks of its existence it was twice washed away by the 
violence of the waves. The zero of the tide-gauge is 20°59 feet 
below the bench-mark at the pier-head. The time at noon is found 
by a gnomon attached to the flag-staff near the guard-house. 
The meteorological instruments are erected in the guard-house 
of the station, and arein charge of the chief boatman. The cistern 
of the barometer is 6:4 feet above the bench-mark. The diameter 
of the tube is 0°32 of an inch. 
CauircivEen (Co. Kerry).—The tide-gauge at this station is 
' placed in an angle above the bridge, in a very sheltered situation, 
and having the advantage of deep water at the lowest tides. The 
only objection to its position is that it is not situated on the open 
sea, and the tide at Cahirciveen must be considered as a river tide. 
There is no Ordnance bench-mark at this station. A provisional 
mark was therefore placed on the corner coping-stone of the bridge; 
and the zero of the tide-gauge was found to be 23°51 feet below it. 
The barometer is erected in the house of the officer of the station, 
in the town of Cahirciveen, and the thermometers and rain-gauge in 
the garden attached to it. Their site is not very favourable. The 
cistern of the barometer is 37:0 feet above the mark on the bridge. 
The diameter of tube is 0:38 of an inch. The brass vertical gnomon, 
for finding the time at noon, is placed on the sill of a window of the 
officer’s house. 
CasTieTownsznn (Co. Cork).—The tide-gauge at “ee station is 
_ in an excellent position, although rather exposed. It is erected in 
the open sea, and is held in its place by guys and chains which are
