Dear Dr. Gartland: 
I have seen the letter from Jeremy Rifkin at the Foundation on Economic 
Trends in which he notes the work of Brinster and asks to prohibit 
experimentation involving the transfer of a genetic trait from one species 
to the germ line of another unrelated mammalian species. This is merely 
to advise you that I think the work of Brinster is important, will be 
of advantage to all of us and would strongly suggest that Rifkin's 
suggestion be ignored.
