The admirable and known Properties of this Stone, are, 
in general, thefe, That it attracleth Iron 3 or any Body, if 
fmall, which hath Iron in it. That it hath no perception of 
any other Body, though never fo light. That it maketh 
the AttracLion according to its Poles. And that it Commu- 
nicateth to Iron both the fame attractive power 3 and a 
Verticity to the North-Pole. In which lan 1 , lieth its Great 
ufe, as applied to Navigation. Although by Obfervations 
made from the Variation of the Needle, Time may pro- 
duce further Difcoveries in Aftronomy. Thofe that travail 
through the vaft Deferts of Arabia, have alfo a Needle and 
Compafs, whereby they direct themfelves in their way, as (0 Majoli 
Mariners at Sea. (c) The Col,0( * uia '
