When condensed with primary aromatic amines,β :γ -dibromohutane or the corresponding clichloride gives rise to secondary diamines of the following type:— ArNH. CH(CH3 ). CH(CH3 ). NHAr. These bases contain two asymmetric carbon atoms, which are either mirror images of each other or absolutely identical. Like the tartaric acids they should therefore exist in an internally-compensatedmeso -form, as well as an externally compensated mixture, potentially resolvable into optically active modifications. Moreover, the externally compensated mixture may belong to one of three categories, being either (1) a true racemoid, inseparable by purely physical agencies; (2) a conglomerate ofd - andl -crystals, mechanically separable in various ways; or (3) a pseudo-racemoid,i. e ., a special kind of mixed crystal containingd - andl -material in variable proportions.
