Dear Dr. Hobbs:

\J	Thanks for sending me your report \F1A Model for Natural Language
Semantics, Part I: The Model\F0.  I have not had time to read it, but
naturally I turned to your treatment of Mr. Hug.
Unfortunately, \F1while\F0 you take \F1while\F0 to mean \F1simultaneously\F0,
the \F1New York Times\F0 uses the meaning \F1whereas\F0.  \F2While\F0
yours is the more common meaning, \F1Webster's Collegiate\F0 also allows
his.
This leaves you with one less time word to help fix the sequence of events
and requires knowing a bit more about the meaning in order to determine
your lattice.

	I may have a genuine comment when I have had time to read the report.\.
