In this paper a simple tensor form of Dirac's equation is obtained. This is accomplished by considering ψs and γα(rs) of the usual equations as being related to a set of n-beins as invariants corresponding to true tensors ψμ and Γαβσ. The results are, however, independant of the choice of the n-beins. It is thus shown that the introduction of the idea of half-vectors in the quantum mechanics, while undoubtedly desirable when dealing exclusively with cartesian coordinates, is unnecessary.
