of the Royal Society. A committee was therefore 
appointed, in confequence of their application : 
and proper conductors were put up, in the leveral 
places where they were thought necefiary, from 
the top of the lanthorn to the /ewers underground. 
And notwithstanding particular care was taken, 
to have the additional metal either of a confide r- 
able diameter, or an equal quantity of it formed 
into other fhapes, for the conveniency of the feve- 
ral places ; yet part of thole condudtors, confid- 
ing of iron, in the Jlone gallery , fhewed marks of 
their having been made conjiderably hot , if not ab-

the vergers of that church, Mr, Richard Gould) 
who had examined the conductors the morning

the foutb , which was the firit he attended to. That he ex- 
amined next the conductor to the Weft, and obferved a thick 
ruft lying upon the pavement in the ftone gallery, as if it had 
been cleaned off, from the conductor, with a tool: that fe-

or nuts : fomething like the effects left by gun-powder upon 
iron or fteel, or a fmoaky fire. 
That the conductor to the North , fhewed no marks, no 
more than that to the South. 
But that upon examining the condu&or to the Eaft, he 
found ftronger marks abundantly , than on the IVtJt conductor,
