My Dear Dr

Accompanying this
note I send you are official
communication requesting that
you will examine a paper on
nitrification.

You will oblige me if you
can find time, in the course 
of a few days, to look over the
communication and to give
us your opinion as to its
contents.

Our family have returned
in good health and spirits
and are now making preparations
for the winter. They
hope to see you and yours before
or at the time of the Coronation.
