Directions for Culturing Plasma 
October 26, 1940
Dear Sir Edward:
There have been shipped to England 521 liters of plasma-saline to date. By the end of this month, October, it is hoped that
an additional 500 liters will be on the way.
You will find enclosed a copy of the routines followed in an attempt to insure shipment of a sterile and non toxic substance.
We are very anxious to know the condition of this plasma on arrival and at the time it is used, particularly in regard to
possible latent growth of organisms, denaturation of proteins and clinical reactions following its use.
To this end a copy of these routines will be included in each carton, in the future, with the hope that reports will be sent
in to your office or directly here.
Any suggestions which you may have to offer as a result of your observations will be happily received.
