Lucy Slater used Bailey\u27s 6ψ6 summation formula to derive the Bailey pairs she used to construct her famous list of 130 identities of the Rogers-Ramanujan type. In the present paper we apply the same techniques to Chu\u27s 10ψ10 generalization of Bailey\u27s formula to produce quite general Bailey pairs. Slater\u27s Bailey pairs are then recovered as special limiting cases of these more general pairs. In re-examining Slater\u27s work, we find that her Bailey pairs are, for the most part, special cases of more general Bailey pairs containing one or more free parameters. Further, we also find new general Bailey pairs (containing one or more free parameters) which are also implied by the 6ψ6 summation formula. Slater used the Jacobi triple ...
