REYNOLDS: EAST ANGLIAN EARTHQUAKE. 
the Leeds tracing were not due to atmospheric disturbances appears 
ahnost certain, both from the character of the indentations as well as 
from the fact that no other barograph has recorded them. On the 
other hand it is not at all improbable, that the Leeds instrument may, 
by its construction, be particularly sensitive to earth-shakes. It is 
of interest to consider in connection with the present report, that the 
disturbance originating beneath our county, was sufficiently intense to 
cause the ground 170 miles away to be tilted slowly to and fro for 
a period of four hours after the event." 
Note. — Although the following notice cannot be classified 
amongst barometrical disturbances due to abnormal causes, it is so 
exceptional in character that it appears to be desirable to place it 
upon record. 
On Wednesday, Dec. 8th, 1886, a terrible storm swept over 
England, unhappily attended by the loss of more than twenty men of 
the crews of two life-boats on the Lancashire coast. On Dec. 7th, at 
8 p.m., the recording aneroid barometer stood, in Leeds, at 29*43 in., 
and a depression commenced which at 4 a.m., on December 8th, made 
the reading 29 "20; at 10 a.m. it was 28 "So, the fall han-'g been very 
rapid and nearly uniform in speed for ten hours, during which 1 inch 
was lost. The fall continued until 9-30 p.m., when 27*68 was regis- 
tered, being the lowest point reached. The readings of the aneroid 
were controlled at intervals by those of a standard mercurial baro- 
meter. As the charts are not ruled for lower readings than 28 in., 
Mr. Branson provided for the exceptional position by " gearing up " 
the instrument ^ in. The reading now reported appears to be 
lower than any previous one noticed in local records. The force 
of the wind in Leeds was not so gTeat as to prove destructive.
