Abstract
Experimental evidence for the existence of optically biaxial lyotropic nematics is presented. The first experimental measurements of the optical uniaxial birefringence versus the temperature in a discotic nematic are reported; they show a discontinuity of at the discotic-calamitic phase transition.
