Point-contact spectroscopy has been used to study the superconducting properties of the heavy-fermion system UPt~ down to about .40 inK. The differential resistance of heterocontacts between UPt3 and Pt shows, for current flow parallel to the c direction, a distinct minimum at a low bias due to Andr
