Note

First English edition.

The first Latin edition was published in 1631 under title, "Arithmeticae in numeris et speciebys institvtio: qvae tvm logisticae, tvm analyticae, atqve adeo totivs mathematicae, qvasi clavis est." Translated in greater part by Robert Wood as is stated in the preface to the 1632 Latin edition.--NUC pre-1956 imprints.

Errata: p. [12].

"A most easie way for the delineation of plaine sun-dials, only by geometry, without any trigonometricall calculation .." has caption title and separate paging.

Uncontrolled note

Probably in fact a translation of "Clavis mathematicae"--ST
