DISEASE GERMS

To the Editors of the CRIMSON:

We wish to correct any misconception that might be engendered by the opening paragraphs of your article of December 21 on chemical and biological warfare.

The latter part of the CRIMSON article accurately gives our reasons for opposing the employment in Vietnam of riot gas and anti-crop chemicals, as actions likely to erode the restraints on the use of chemical and biological weapons generally.

The first portion of the article, however, could give the impression that the United States may be spreading disease germs over targets in Vietnam. We have no reason whatever to believe that any biological weapons are being used in Vietnam. John T. Edsall   Prof. of Applied Microbiology   Matthew S. Meselson   Prof. of Biology
