Dear Josh:
I got quite a kick out of receiving your publication.  I got quite a jolt when I tried to read and follow the contents.
I'm still valiantly after anything to visualize the scientific implications of your paper.
In the meantime would it be possible for me to get a vial or two of the Penicillium notation?  The boys in Bio shop grew very successful cultures last term.  Were neglected over the summer and so the species became contaminated.
Thanks.
Sincerely,
Abraham Penzer
P.S. Your brother did "all right" too.
