Intending to prepare a durable test-piece for the determination of shrinkage temp. that serves to characterise skins, effect of treatments on the shrinkage temp. of skins is studied. It is found that the shrinkage temp. decreases as the stored days of skin increase (Fig. 2 & 3), and is lowered by dehydration with hot (30-40°C) acetone, but not change with cold (7-10°C) acetone (Tab. 1 & 2) & that shrinkage temp. of dehydrated skin does not change during 3 wks. preservation.
