Dear Joshua,
Thank you for your letter,

I can quite understand that you are sceptical
about our results. No one has yet conclusively
shown transformation in coli, On the other hand,
I can assure you that we are quite satisfied with
our own results. I am looking forward very much
to hearing that you have confirmed them,

With kind regards,

Yours sincerely,

geo .
