This letter is not the place to discuss in great detail such scientific 
gains as might be achieved. However, we would be most happy to suggest 
qualified experts if testimony should be required now or in the future. 
In summary, we vigorously oppose the proposed amendment. We think 
it has no merit and potentially might restrict very beneficial research and 
development in one of the most exicting areas in recent times. 
Sincerely 
Preston V. Dilts, Jr., M.D.
