[Footnote 558: Lit. "Instruments of astronomy or astrology" (tenjim); but tenjim is also used in the sense of geomancy, in which operation, as before explained, astrology plays an important part, and the context shows that the word is here intended to bear this meaning. Again, the implements of a geomancer of the higher order would include certain astrological instruments, such as an astrolabe, star-table, etc., necessary, as I have before explained, for the elucidation of the scheme obtained by the sand-smiting proper.]
