Dear Dr. Gartland: 
Thank you for your recent memo which solicited comments on the 
revised Guidelines for Research Involving Recombinant DNA 
Molecules. Our current, and currently planned experiments, 
involve organisms that naturally exchange genetic material 
by known physiological processes, and therefore are exempt 
from the Revised Guidelines. Therefore, we have very few 
comments to offer. In general, however, we have no problem 
with the Guidelines in their present form. 
Sincerely , 
P. J 7 . Kretschmer, Ph.D. 
Biotechnology Supervisor
