The guidance and counsel of the Project Supervising Committee under the chairmanship of C . F. Mengers were very helpful. Thanks are due to E. B. Shultz! Jr., ivho designed most of the equipment and helped develop much of the experimental procedure. F. C. Rac. N.Mechales. A . E. Richter, and R . l', Johnson assisted in conducting tests. D. M. Mason and J. E. Seuzil supervised the analytical Lvork.
