and with which he did no w a&ually lift before ns 3 1 
pounds 9 ounces and three fourths. 
The temper’d needle fpoken of above, and which 
had nearly loft all its virtue, had the fame again re- 
ftored in great meafure, upon being touched in the 
common way, on the armed poles of this artificial 
magnet 5 after which it difcovered a ftrong verticity, 
and was able to lift at one of its ends, the heavier 
of the 2 abovementioned weights, that is to fay 
fomewhat more than three quarters of an ounce. 
The hard needle which ftill retained, as has been 
obferved, a confiderable part of the virtue it had 
acquired by the touch of the large fteel bars, was 
laftiy touched alfo in a contrary fenfe, upon the 
armed poles of this artificial magnet 5 whereby it not 
only loft the polarity yet remaining, but acquired a 
new one the other way, it would not however after 
this laft touch lift more than nine pennyweight. 
This is the true fubftance of the minutes, 1 took, 
when thefe experiments were made, and which I 
prefume will now be verified by thofe Mr. Knight 
is here prepared to fhew. 
AFTER the reading of this repott, Mr, Knight 
did accordingly produce before the Society the two 
large bars ^nd all the other particulars therein men-

vantagious circumftances of the place, fucceeded 
perfe&ly in every particular, and to the entire fatif- 
faction of all the company.
