The author considers the conformal relation between twistors and spinors on a Riemannian spin manifold of dimension \(n\geq 3\). A first integral is constructed for a twistor spinor and various geometric properties of the spin manifold are deduced. The notions of a conformal deformation and a Killing spinor are considered and such a deformation of a twistor spinor into a Killing spinor and conditions for the equivalence of these quantities is indicated.
