Dear Joshua:

I am writing in reference to your seminar at the
Foundation either in late spring or early fall. The
dates June 11, September 17, and September 24 have been
reserved for you. If any of these dates are inconvenient,
would you like to select a monday after September 24?
In addition to the selection of the date, I should also
like to know the title for your seminar.

Livi i 7d

Best regards.
Sincerely yours,

Ralph I. Dorfman
