page 346 note 2 Syst. Min., 6th edn, 1892, p. 77. Dana uses the conventional orientation with b as symmetry axis ; further, Scaeehi's A = Dana's c{0Ol}, B = a{100}, m = μ{110}, n = n{1¯11}, and e = e{2¯01}.
page 346 note 3 Handb. Min., Bd. I, Abt. 4, p. 695. Hintze uses the same orientation as Dana but retains Scaeehi's significant letters except for n; Scacchi's n = Hintze's u.
