✦ Synopsis

A genera1 expression for the osmotic bulk modulus and its pressure derivative of a colloid crystal of infinite rod-like molecules is derived. This result is based on an exact solution of the Poisson-Boltzmann equation within a Wigner-Seitz cylinder and a recently derived expression relating the osmotic bulk modulus to the counterion density at the edge of the Wigner-Seitx cylinder. The osmotic bulk modulus and its pressure derivative of the myosin-rod lattice found in striated muscle are calculated and found to be in good agreement with experiment.
