Guinea Pigs?

To the Editors of The Crimson:

The article on July 10 by Philip M. Rubin ("Selling Our Bodies") prompts me to remind your readers how times change.

Forty-five years ago many students, myself among them, volunteered to be guinea-pigs in medical experiments with no compensation. We felt the experiments were important and trusted our mentors.

Twenty years ago, volunteers could be found only if there was compensation.

Today, Mr. Rubin, and many others, reject any such participation, and tend to regard the payment of compensation as an indication that the activity is undesireable.

Who was right? That would make an interesting PhD thesis. Richard Wilson   Mallinckrodt Professor of Physics
