Title: Preliminary Results on the Measurement of Mass and Width of the W
Boson at LEP in  e+e- interactions at sqrt(s) up to 202 GeV.

We report on measurements of the mass and total decay width of the W
boson with the L3 detector at LEP.  W-pair events produced in e+e-
interactions between 161 GeV and 202 GeV centre-of-mass energy are
selected in a data sample corresponding to a total luminosity of approximatly
490 pb-1.  Combining all final states in W-pair production, the mass
and total decay width of the W boson are determined.  These results
are preliminary.
