Note 31 — Chapter VII · DIURNAL AND NOCTURNAL
J. M. Ashmand translation
Whalley here appends the following note: “To this chapter may be properly added, that a planet is said to be diurnal, when, in a diurnal nativity, above the earth; and, in a nocturnal nativity, under the earth: but nocturnal, when, in a nocturnal nativity, above the earth; or, in a diurnal nativity, under the earth.”
