Only when J come to ſet one Foot of the Compaſſes to 48 gr. 45.for the finding of a quarter paſt 3, the other Foot will fall out of theLine, and then I may either take out ſo much as is out of the Line beyond45 gr. and turn it back into the Line, and it will reach from 43 gr. to41 gr. 45 m. or L may uſe croſs work, extending the Compaffes Krennthe Sine of 90 gr. to the Tangent of 48 gr. 45 m. ſo the ſame extem willreach from the Sine of 51 gr. 30 m. to the Tangent of 41 7. 45 m. Andſueh is the diftance of the Line of 3 Hours à from the Meridian. a

This done, I come to the Plane, and there according as the Lines dofall in the Fundamental Piagram, 55 1, draw the Right Line S N, ſerving for the Meridian, the Hourof 12, and the Subſtylar. a i
