    Notes: A comparison of dynamic methods for osmotic pressure molecular weight determinations has been made between the authors' method, the recently published method of Elias, and two other commonly used procedures. Samples containing various amounts of membrane-permeating solute were studied while using the same osmometer and gel-cellophane membrane. Good agreement is shown between the authors' method and that of Elias for all of the samples. The Fuoss-Mead technique and Philipp's method do not measure as much of the permeating solute when present in large amounts. The method of Elias is subject to continual calibration because of pore blockage and was found to be considerably more time-consuming than the authors' method.
