How to find the Longitude of any starre by the Globe. The 28. Proposition

I Haue told you in my Spheare, that the Longitude of any starre is that arch or portion of the Eclip∣tique line, which is contained betwixt the first point of Aries, and that Circle which passeth through the Poles of the Zodiaque, and also through the bodie of the starre, which Circle, the semi-Circle of Longitude and La∣titude here representeth: and by making the saide semi-Circle to passe through the starre called Hircus before mentioned, I finde that the number of degrées of the Ecliptique, contained betwixt the said Circle and the first point of Aries to be 75. degrées & 30′· which is the Longitude of the said starre, and thereby maketh his place to be in the 15. degrée 30′· of Gemini, as before is set downe in the last Proposition.
