Abstract

The refractive index of marine diatoms is measured by immersing them in a solution of pyridine and water. As the refractive index of the solution approaches that of the diatoms, the diatoms tend to disappear. Using this method, the refractive index of Skeletonema !R. was measured to be 1.457 * 0.005
