Additional errata for Chapter 3:

Page 74, line 6 - goose  +N +SG should read goose  +N +PL

Page 75,  Tlex is defined as Tnum dot Tstems.  Should read Tstems dot
Tnum. This is because the transducer Tlex, in composing two transducers
Tstems and Tnum, first maps nouns into noun root class (using transducer
Tstems) and then (using transducer Tnum) identifies the nominal
morphological features (+PL, +SG).
