C'trculm Nauticmy ( the Mariners Bpx or Compafs.^) but. not till 
Then, And he who .firft contrived this Application, did' cmpkat 
this Invention of Qr cuius Nauticm, But all thoft antecedeni: Dif 
eoveries were fteps towards it, and Parts of the Invention.. 
Now itis not likely, that all thefe Di^co^^erles were made at 
once (by the lame Man, atthe lame.T'iiieJ 'but Succefi^x^- • I7 
thejoint Advice^of divers Ihquiliti",!^e;Alen,, :and in a co^. . 
traa of Time yet all perhaps of the fame Nation, and (proiMbiy) 
the EngHjh. ■' 
But, whoever gave the firft Hint of this Invention-, certain itis, 
th.dit the grmt lmproveme/its of tlie Magnetick Do&rlne are due 
to xhQ Englifor-i and chiefly to thofe about Ldndon^ and Grefnam- 
College.- And it is fit the Meitiory of it flioiild be prefervedr 
/ The^' Cafe is much the 'fame with that of P/v/;///?^, which we 
cannot teafonably fuppofe to be invented all a| once ^ nor perhaps 
all by the fame Man ^ But rather, by the conciiiieat advice of di- 
vers, and iti a Gonfiderable tract of time, before it come to that de- 
gree .of Per fefti'on, wliich we now C3llPrimr/ig, . 
It might he firft obfeived, that -the fhape of a Letter, Figure or 
Piaure, graved, -on Wood or Metal, ipight (with help of a conve- 
nient prepar|tioii of Oil, Ink, .or coloured Liquor) be ftampej on 
Paper. And, if once, then as oft as you- pleafe; 
And, if by ftamping the Print on Paper, tlien (as well j by. dae 
application of the Paper to the Print, thus prepared. . 
Andj if one, ' then Cby the fame, reafon) ro two or more (if fidy 
conjoined) and even to a whole Page; at once :, and, of that., as ma- 
ny Copies as v\/e pleafe. ' , . . ' ' , 
But ( this being admitted ) it remains further, to be conrrived.,^ 
how all thefe Prints or Stamps ffor a v\/holePage) iha ll be focom- 
pofed into one Frame, that the Paper may be applied to all at 
once. 
It is then to be confidered further, what kind of ( or fome- 
mlrdt inftead of Ink) is to be applyed to the Face of the Letters 
thus compofed. For common Wrl ting-Ink will not ferve the turn. 
Then, How the Paper (hall be applyed C with an Equal pref- 
fure, and fufficient) fo as to take oft^ juft fo much of that Ink, as 
reprefents the Face of thofe Letters, and no more. - 
And, after all -this, it muft be further contrived, How re 
fucji a Structure, as what we now call a Frijitirig-Frefs : , 
How to manage it^ fo as to anfwer all thefe Exigences. For^ tiil
