1. The mean diameter of rabbit erythrocytes immersed in hypotonic plasma is measured by diffractometric methods, and the results show that the diameter decreases about 8 per cent. as the cell‐volume increases about 45 per cent., after which lysis results. 2. This figure is smaller than that obtained in earlier experiments (which show about 14 per cent. decrease as a maximum), but the higher figure previously obtained is probably due to unavoidable, or at least very small, errors associated with the photographic method of measuring red‐cell diameter.
