Fig. 2. Rana sylvatjca. Relationship (A) between temperature and final ice content of 250 and 500 mOsm solutions, and (B) between plasma glucose levels and Ice content of frogs frozen at -2 to -3°C for 24 h. Solid boxes and open boxes denote ice contents of 250 and 500 mOsm solutions, respectively.
In (B) the ice content and plasma glucose values were measured for R. sylvatica collected from western New
