Typical examples of salt loss into isotonic (600 mM) or moderately hypotonic sugar solutions after adaptation to sea water of chlorosity 10 Least change of volume usually in approximately 90% of isotonic value. Control curves (distilled water) are from Figure 1. Loss is slightly increased from N. succinea, but no effect is demonstrable in N. diversicolor or N. limnicola. All curves from conductivity measurements. the acute salt-loss tests, the salt loss rate might thereby be increased. Accordingly, a number of experiments have been made in which isotonic solutions of dextrose, sucrose, or galactose have been substitute for distilled water in standard salt-loss determinations. The results (Fig. 4) reveal no increase in salt loss rate in N. diversicolor or N. limnicola, species in which the extent of osmotic swelling in distilled water is slight. It has been consistently noted that a sugar solution isotonic to the adaptational sea water causes some loss of volume during the exposure; this volume loss is attributed to output of urine while osmotic water.
