SummaryPreparations of bovine platelet cofactor I have been examined according to biophysical methods. In the ultracentrifuge the patterns reveal a major component comprising 86% of the total and two faster moving minor components. The sedimentation constants are 6.65, 10.0, and 21.2 Svedberg units. The diffusion constant is 3.30 × 10−7 cm2 sec−1. Associating this value with the main constituent, the molecular weight is found to be 196,000. A molecular axial ratio of 12 is also obtained from these data. An axial ratio of 8 is indicated from viscosity data. The extinction coefficient at 2800 Å is 14.8.

This paper presents values of the temperature coefficient of the diffusion constant of copper in aqueous solutions of sulphuric acid containing copper sulphate, for the range 10° to 25 °C. and four acid concentrations. The work is based on the Mathematical Theory of the Changes of Concentration at the Electrode, formulated by Rosebrugh and Miller. Evidence is presented supporting the choice of a new point on the oscillograph potential curve for the measurement of t. The values of K, thus obtained, at 18 °C. are in agreement with those of Cole and Gordon, who used the method of Northrop and Anson. The values of K at 10 °C. calculated from those at 25 °C. by means of viscosity data are in agreement with the values obtained by experiment.
