direction that it might be attributed to the removal of a larger load from 
the hill side of the instrument than from the valley side. 
Between June 6 and 7 the maximum temperature fell to 65°, from 
which it rose to 68° on the 11th. During this time, however, the pendu- - 
lum crept eastwards, or in the opposite direction to that in which, under 
similar conditions, it had been previously moving. From June 11 to 13 
the temperature rose from 65° to 72°, whilst the pendulum remained 
stationary. 
What these observations show for a period of only twenty-one days is 
true for longer periods, as observed in Japan, and generally agrees with 
the observations made at Strassburg, described by the late Dr. E. von 
Rebeur-Paschwitz. At this latter place, for a period of nineteen months, 
the character of the curve of wandering is similar to that for a curve of 
temperature ; but when we observe, as this author points out, that the 
minimum of temperature is reached from 14 to 2 months before a mini- 
mum in the curve, showing the displacement in the pendulum, whilst its 
maximum is reached about four months later, the relationship between 
the two becomes obscured. This and other results obtained at, Strass- 
burg are shown in fig. 10, reduced from the observations of von Rebeur.

Tn this diagram the temperature curve taken in the cellar where the pen- 
dulum was installed is shown in dots. H P is the horizontal pendulum 
curve, La curve from level observations, and N a Nadir curve. An in- 
crease in reading indicates a movement towards the north. Although, 
these three sets of observations were made with instruments near to each 
other, the difference of the Nadir curve from the other two is very strik- 
ing. The amounts of change are also noticeable, the horizontal pendulum 
having been tilted towards the south through 87", and if we take it from 
the commencement of the observations in April, 1892, this is increased 
to. 143”,
