Mr. Thomas Heath, who is in charge of the instrument, states that 
only one of the above coincidences is of an oscillatory character. A 
number of tilts and slight bends were recorded, but only one of these, on 
April 23, from 0h. 18m. to Oh. 36m., was oscillatory. The bends and tilts 
were most numerous in March, April, and May. From May 30 to 
November 11 there is practically not a trace of any kind of disturbance. 
From the latter date to the end of the year the number of tilts is small. 
A second pendulum was placed in position on May 14, and a couple of 
thermometers were installed in the pendulum chamber on May 31. They 
are covered by an earthenware dish. Between May 31 and March 20 the 
maximum temperature was, on September 21, 63°-2 ; the minimum was 
51°-0 on February 26.
