Sir;

Your morning reports show that the recent directions given you have been departed from, as with 1008 patients Four (4) Divisions, each with a capacity of 400, have been opened. You are again directed to conform to those directions, unless you receive notifications of their withdrawal. If any contagious or infectious disease occurs rendering any change necessary, you will report the fact.

Very Respectfully,
   Yr. Obdt. Servt.
