Physiological studies on trematodes: the osmotic activity ofGastrothylax crumenifer

Abstract

The percentage change in weight, at 38·2 °C, in different concentrations of sodium chloride at different intervals, of a trematode,Gastrothylax crumenifer, from the reticulum of buffaloes has been recorded.A state of approximate isotonicity is reached between 0·4 and 0·5% sodium chloride.The osmotic pressure has also been expressed in terms of freezing-point depression.
