De numeratione parallaxis Solis& Lunæ. Cap. XXVv.
5 Odum quoq́; numerandi parallaxes Solis& Lunę per Canonem breuiter exponemus. Siquidem per
iſtantiam à uertice Solis uel Lunæ duplicatam, ca
ſhpiemus in tabula parallaxes occurrentes. Solis ꝗdẽ ſimpliciter, Lunæ uero in quatuor ſuis limitibus,& cum motu Lunæ, ſiue eius à Sole diſtantia duplicata, ſcrupula proportio- num priora, quibus cũ accipiemus utriuſq; exceſſus primi& ul timi terminũ partes proportionales ad IX. quas à proxima ſe⸗ quente cõmutatiõe ſemper auferemus, ac poſteriores ei quæ in pPenultimo limite ſemper adijciemus,& habebimus binas Lunę parallaxes rectificatas in apogæo& perigæo, quas epicyclus mi nor auget uel minuit.
