1. Magnetical Ohjeryations and Experiments 5 by 
Servingcon Savery, o/Shilfton. 
PRECOGNir^. 
I. HAT which I call the Magnetical Line, is 
■ the Pofition of a Dipping-Needle when it 
ceafeth from ofcillating, and is at Reft in the magneti- 
cal Meridian of the Place. 
II. By the Word Magnet (unlefs diflinguifhed) I 
would be underflood to mean not a Loadflone only, 
but either that, or Iron or Steel, when they have per- 
manent Polarity, or any thing elfe (if to be found) 
which has a fenfible magnetical or polar Attradion. 
III. Of the magnetical Needle, I always call that 
the North End which (if hung horizontally) natu- 
rally turns to the North, and that the South End 
which turns to the South : But when I ufe the Words 
Pole of a Needle, I call that the North Pole thereof 
which turns to the South, and that the South Pole 
of it which turns to the North. 
iV. Of Touched Iron or Steel (or of Untouched, 
fo long as it remains in a Poflure which gives it Pola- 
rity) as well as of the Loadflone itfelf, I call that the 
North Pole which attrads the North End {i.e.) the 
South Pole of the Needle, and that the South Pole 
which attrads the South End, or North Pole of the 
Needle : Or in other Words, I call that the North 
Pole, in all Sorts of Magnets, which is endued with 
the fame kind of Vertue which the North Pole of 
the Earth hath, and confequently is repelled thereby :
