Dear Dr. Gartland, 
I strongly support the amendment to section I-D submitted 
by Drs. Richard Goldstein and Richard Novick regarding "The 
Construction of Biological Weapons by Molecular Cloning". 
I agree that the development of biological weapons based 
on the use of recombinant DNA technology should be prohibited. 
Sincerely, 
H. Murialdo, Ph.D. , 
Associate Professor.
