Not a misprint. It occurs in the Astrology Classics Medical Series reprint edition published by AstroAmerica as well as the original facsimile edition published by Kessinger. Meno, month; graphic, written.is menographic possibly a misprint? Menographic is unknown to my dictionaries.
I suspect the orb values provided by al-Biruni may be idealized: if one takes Saturn (9?) and the Moon (12?), their values differ from each other by a difference of 3?; if one takes Jupiter (9?) and Mercury (7?), their values differ from each other by a difference of 2?; and if one takes Mars (8?) and Venus (7?), their values differ from each other by a difference of 1?. In other words, the difference in orb values between these planets descends from 3 to 1 in an ordered sequence of proportions.
In practice, Morin distinguishes between what he calls the extension of the "influential force" of a planet and its "intensity of influence." He states that the influential force (strength) of the Sun is 18?, that of the Moon is 15?, that of Saturn and Mars is 12?, that of Jupiter, Venus and Mercury is 8?. Then he adds, "In reality, no mortal can determine the influential force of a planet with precision." Thus, perhaps, the idealized orbs of al-Biruni.
