M. Blundevile his exercises containing sixe treatises, the titles wherof are set down in the next printed page: which treatises are verie necessarie to be read and learned of all yoong gentlemen that haue not bene exercised in such disciplines, and yet are desirous to haue knowledge as well in cosmographie, astronomie, and geographie, as also in the arte of navigation ... To the furtherance of which arte of navigation, the said M. Blundevile speciallie wrote the said treatises and of meere good will doth dedicate the same to all the young gentlemen of this realme.

How to know by the Globe at what time any star riseth a∣boue the Horizon, mounteth to the highest, and setteth, and with what degree of the Ecliptique he riseth, mounteth, and setteth, and also in what part of the Horizon he riseth and set∣teth. Proposition. 23. (Book 23)

HAuing rectified the Index of the houre whéele by the 7. proposition, bring the Star to the East part of the Horizon, so as it may touch the edge thereof, and the Index of the houre whéele will shew at what houre hée riseth and by looking at that instant to the Ecliptique line you shall sée what degrée of the Ecliptique riseth then with him. That done, bring the said starre to the brazen Meridian, and the Index of the houre whéele will shew at what houre hee is at the highest, and there staying the Globe, marke what degrée of the Ecliptique line doth fall right vnder the brazen Meridian at that instant, for that degrée is sayde to accompany him when hée is at his highest. Then bring the sayd Starre to the West part of the Horizon, and you shall finde by the Index of the houre whéele at what houre hee setteth, and what degree of the

Ecliptique doth accompany him at his setting. As for example, I would knowe the sixtéenth day of Iune 1590. the sunne being in the fourth degrée of Cancer, when Arcturus otherwise called Ba∣bulcus and Lanceator doth rise, mounteth to the highest, and set∣teth, here hauing rectified the Index of the houre-wheele by the seuenth Proposition, I bring the said starre of the East part and very edge of the Horizon, and I finde that he riseth a little before twelue of the clocke at noone, and that the 28. degrée and 30′· of Virgo, riseth with him, and by looking amongst the windes vp∣on the Horizon right against the place of his rising, I find that he riseth Northeast and by East. Secondly by bringing the said star to the brazen Meridian, the Index of the houre-whéele sheweth that he is at his highest halfe an houre after seuen of the clocke at night, and is then plaine South, and that the 29. of Libra, doth then accompany him. Thirdly by bringing the saide starre to the West part of the Horizon, the Index of the houre-whéele sheweth that he setteth or goeth downe a quarter of an houre before foure in the morning, and that the fourth degrée of Capricornus doth accompany him at his setting: and by looking there vpon the Ho∣rizon, I find amongest the winds that the said star setteth North∣west and by West.
