ELASTICITY, DOUBLE REFRACTION AND SWELLING OF ISOELECTRIC GELATIN
Quincke's researches (1904) have demonstrated that when a 20 per cent gelatin gel is allowed to swell in water it gives rise to positive double refraction, as if the gel were under tensile stresses. If, on the other hand, the gel shrinks on being placed in alcohol it becomes negatively double r...
