April 16. The needle at intervals was attracted to the eastward or 
repelled to the westward, and remaining there stationary for a 
minute or two, returned to its former place: the wind was unsteady 
from the NW, accompanied with showers.—26. The needle was 
similarly affected, and the wind was in the same point: the subse- 
quent day apparently thunder showers were seen in different parts; 
but no thunder was heard, neither did any rain fall at Bushey Heath: 
the wind was unsteady from the NE, and during the night of the 
26th it blew hard.—April 30, in the evening, the variation was 
24° 44’ 15”, it decreased to 24° 16’ 45”, and again, increased to 
24° 47’ 50°: for this unusual variation there appears no cause: 
several black dense clouds were visible, and the weather squally, 
with showers; and during the day there were several violent hail- 
storms.
