The thermograph is on its north side, facing due N.W. 
1-N., and on the first story. The buibs of the instru- 
ments are at a height of twelve feet above the ground, 
and about twenty feet above the sea level. The exposure 
is very good, as there are no buildings or trees in the 
vicinity to affect the readings. 
ARMAGH.—The observatory is on a rising ground close 
to the town; it is situated in the centre of an ordinary 
garden and pleasureground, containing trees and shrubs 
ef moderate size. 
The anemograph is erected on the roof of the house, 
and raised seventeen feet above it, and is thoroughly well 
exposed to all points, excepting that the country about is 
undulating and fairly well wooded, which has the effect of 
retarding the motion of the air. 
The thermograph screen is erected on the north side of 
the meteorological observatory; the bulbs are at the 
distance of four feet from the ground, and about 206 feet 
above the sea level. The exposure of the screen is good, 
though there are trees and shrubs about it. However,

Dr. Robinson has satisfied himself by an independent 
series of observations that the record taken in the screen 
gives the true temperature of the place. 
GLasGow.—The instruments are at the astronomical 
observatory, which is placed on a slight rising ground at 
the west side of the town, and commands a clear view of 
the horizon in all directions. It cccupies a central posi- 
tion in the valley of the Clyde, which is about 16 miles 
in breadth at that place. The bounding hills to the 
north are about 800 feet in height, those towards the 
south are about 4oo ft. high. 
The prevailing south-westerly winds sweep along the 
estuary of the Clyde and reach the observatory without 
much interruption, 
The exposure both of the anemograph and of the 
thermograph screen is very satisfactory. The former is 
on the roof of the building, the latter is attached to the 
north wall of the tower in which the equatoreal is placed. 
The bulbs are 7ft. above the ground, and about rgoft.
