We have measured dijet angular distributions at s**(1/2) = 1.8 TeV in the CDF
detector at the Fermilab Tevatron p anti-p Collider and find agreement with
leading order QCD.  By comparing the distribution for the highest dijet
invariant masses with the predictions of a model of quark compositeness, we
set a lower limit of Lambda(c) >= 330 GeV.
