The spherical basis of astrology;

Dalton’s work argues for a geometric or spherical foundation for astrological interpretation, emphasizing the spatial structure of the heavens. Its historical interest lies in efforts to rationalize astrology through mathematical and astronomical principles, and readers will find technical discussion of celestial configuration and astrological theory.

Joseph Grinnell Dalton appears to be an obscure or little-documented author associated with esoteric or occult literature. I cannot confidently identify him from standard reference knowledge, so I would note him only as a name connected with the field without further specific claims.
