To know the very equacion of the degrees of the Sun, if it so be that it fall betwixt two almican∣teras.

FOr as much as the almicanteras of thine Astrolaby ben compowned by two and two, whereas some almicanteras in some Astrolabies be compouned by one, or else by two, it is necessary to thy learning, to teach thee first to know, and wriche with thine in∣strument: wherefore, when that the degree of the Sunne falleth between two almican∣teras, or else, if thine almicanteras ben gra∣uen with ouer great a point of a Compace, for both these things may cause errour, as well in knowing of the tide of the day, as of the ve∣ry ascendent. Thou must werken in this wise: set the degree of the Sunne vpon the higher almicanteras, as of both. And wait wel where thy almury toucheth the bordure, & set there a pricke of ynke, set adoune again the degree of the Sunne vpon the nether almicanteras, or both, and set there another pricke: remeve then thy almury in y^• bordure, even amiddes both prickes, and this woll leaden justly the degree of the Sunne, to sit betweene both y^e almicanteras in his right place. Lay then the labell on the degree of the Sunne & find in the bordure the very tide of the day, or of the night. And also verely shalt thou find vp∣on thy East orizont thine ascendent.
