How to knowe how long any starre continueth aboue the Horizon in euery Latitude. The 25. Proposition. (Book 25)

BRing the Finitor to your Latitude, and looke in what point the Parallel or declination of the starre cutteth the Finitor, and the number of the Meridians in the Mater contained betwixt the limbe▪ and that point do shew the halfe time of his abode aboue the Horizon, which being doubled is the whole time of his abode aboue the Ho∣rizon. And in numbring the said Meridians whereof 15. do make an houre, remember to beginne to count from the right side of the Mater, procéeding towardes your left hand, and remember also that the middle Meridian or Axletrée, signifieth alwayes the sixth houre, so shall you not erre in your account. As for example, ha∣uing brought the Finitor to the Latitude 52. looke in what point the Parallel of the foresaid starre Oculus Tauri cutteth the Fini∣tor, & by numbring the Meridians procéeding from the limbe on your right hand towardes the left, you shall finde the Parallell of Oculus Tauri, being 15. degrées 49′· to cut the eleuenth Meri∣dian, which being doubled and then the summe thereof deuided by 15. maketh 14. houres and 48′· as before.
