  I present two analyses done with the CLEOIII detector at CESR. The first is a
search for the Lepton Flavor Violating decay Upsilon to mu tau, with
preliminary results, and the second constrains Lepton Universality in Upsilon
to tau tau relative to Upsilon to mu mu. This second analysis, whose results
are final, has dramatically improved uncertainties relative to other such
measurements, and is also the first observation of the decay Upsilon(3S) to tau
tau. A limit is also set on the involvement of a CP odd Higgs in the decay of
the Upsilon(1S) to tau pairs.
