We report on measurements of the cross section as a function of the momentum of the second $b$ and as a function of the azimuthal separation of the two $b$ quarks, for transverse momentum of the initial $b$ quark greater than 15 GeV. Results are compared to QCD predictions.4 pages, Latex (uses the world_sci and epsf macros). 3 uuencoded postscript figures appended. Talk presented at DPF '94High Energy Physics - Experimenttext
