/ Forming and Placiug of the Style. 155from C to 7 is 15, and from 7 to 8 js 15, Cc.) and ſince chat CGis 6gr. 17 min. If C G be taken out of C7 which is 15 gr. therewill remain G 7, 8 gr. 43 min. To which, if you add from 7 to 9,which is two hours or 30 degrees, the Sum will be 38 gr. 43 mn. whoſeComplement is 51 gr. 17 min. If now you make the Angles G MR,and K N 8, each 51 gr. 17 min. they will cut the Deflection Line G K,in R and S. And if further, to the Radius G R you deſcribe the ArkRT; and to the Radius K S you deſcribe the Ark RT; and to theRadius K S you deſcribe the Ark S V; and draw the Line T V, aTangent to both theſe Arks, the Trapexium GTK V ſhall be the par-tern of your Stile. In placing which, you muſt be careful that theſeperpendicular Lengths G T and K V perpendicular I ſay to T V thefiducial Edge) be juſtly placed upon the two aſſumed points at G and.K.—Or having found& 7 to be 8 gr. 43 Min. you may add to it from7 to 10, which is(three hours or) 45 degrees, The Sum will be 53 fr.43 min. whoſe Complement is 36 gr. 17 min. If now from the pointsO and P(Where the ſaid hour of 10 cuts the two fore- mentioned Per-pendiculars G O and K P) you make the Angles G O Rand KP S, eachequal to 36 gr. 17 min. they will cut the Deflection Line G K in the

ſame two points Rand 8. After which yeu may proceed to make chepattern of your Stile, as before.

G 1. Note, That in performing the fifth Section of this Pro-poſition, inſtead of taking thoſe Hour points from the Cen-ter of your Quadrant upon A C the ſide for your Quadrant(it thoſe Diſtances ſhould be too great of your Plane) youmay lay the Thred any where upon the Quadrant, and in-ſtead of taking from the Center to the fore. named Points,you may take the leaſt Diſtances from the ſaid Points tothe Thred, ſeverally, and ſet them down from C to 7 and5, and from C to 8 and 4, and ſo to 9, 103 and for 11,you muſt take from the Point 7 to the Thred, and ſet it

twice from C; by which means they will be all of leſs Di-

ſtance from C. And then all the work is to be continued,as is before preſcribed. Or if che ſaid Diſtances ſhouldbe too little, you may double, triple, or,& c. to make themgreater.

4 2. Note again, That in Decliners from the North, that Dif-ference of Longitude which you find by the ſeventh, is to bereckoned from the North, and ſo che Complement of it is
