To the Prefident and Council of the Royal Society. 
Gentlemen, 
PURSUANT to your refolution, appointing us a committee 
to examine the Houfe of Induftry at Heckingham' in Norfolk, 
which had been ftruck by lightning although it was armed 
with conductors, we arrived there on the 21ft of January. 
Seven months had then elapfed fince the accident, yet we had 
the fatis faCtion to learn, that no material changes had been 
made in the conductors or the building in that period ; lome 
laths that had been burnt, fome bricks and pantiles which had 
been damaged or thrown down, were replaced ; but we found

workmen who had been employed to execute them. In order 
to communicate a clear idea of the accident, it will be neceffary 
to premife a general account of the building ; then to repre- 
fent the manner in which the conductors were applied ; and, 
laftly, to defcribe the ftroke of lightning, with its effeCts.

ter H (fee the general plan, fig. 1.), confiding of a center 
range (Z) and two flanks (Y and X). It Hands on a gentle 
riling, which can by no means be termed a hill, with its front 
facing S. 9 0 W. To the weftern fide of the weft flank, and 
eaftern fide of the eaft flank, fome lower buildings are annexed, 
ferving as offices of different kinds ; and there are two courts, 
one before and the other behind the houfe, together with fome 
fmall gardens and yards on each of the flanks, in all of which 
Hand various detached offices, as will be eafily conceived from 
the general plan (fig. 1.). The
