Title: Measurement of the Probability of Gluon Splitting into
       Charmed Quarks in Hadronic Z Decays


 We have measured the probability, Ng->cc,  of a gluon splitting into a 
 charm-quark pair using 1.7 million hadronic Z decays collected by the L3
 detector. Two independent methods have been applied to events with a
 three-jet topology. One method relies on tagging charmed hadrons by 
 identifying a lepton in the lowest energy jet. The other method uses a 
 neural network based on global event shape parameters.
 Combining both methods, we measure Ng->cc = [2.45 +- 0.29 +- 0.53]%.
