Pelorus Sound is typical of New Zealand coastal locations, i.e. there is a semi-diurnal tide modulated on a spring-neap cycle, generated by the superposition of M2 (lunar, semi-diurnal) and S2 (solar, semi-diurnal) tidal constituents. Other tidal constituents, notably N2 (semi-diurnal, generated by the ellipticity of the moon’s orbit), introduce further modulation, meaning that the spring-neap cycle is not exactly repeated. The tidal range varies between at neap and at spring. (These values are calculated from a sea level time series, July 1997 – February 1998, at Pelorus Sound entrance.) The propagation of this tidal signal into Pelorus Sound has not been well
Disquisitions relating to Matter and Spirit Disquisitions relating to Matter and Spirit Disquisitions relating to Matter and Spirit (1777) is a major work of metaphysics written by eighteenth-century British polymath Joseph Priestley and published by Joseph Johnson. Between 1774 and 1778, while he was serving as an assistant to Lord Shelburne, Priestley wrote five major metaphysical works, in which he outlined his materialist philosophy, even though such a position "entailed denial of free will and the soul." In the first of these works, "The Examination of Dr. Reid's Inquiry. . . Dr. Beattie's Essay. . . and Dr. Oswald's Appeal" (1774), Priestley had strongly suggested that
