Abstract
GARAY et al.1 have reported on experiments on positron annihilation in D and L isomers of various amino acids. I show here that one of the two interpretations which they put forward to explain their results is in error, and also discuss other possible experiments which may enable clarification of the rather unusual results they have reported.
