Medical 2. Engineering 3 Industrial Relations 4. Legal The panel Putting the Disabled Veteran Back to Work a highpoint of the : annual meeting of members was published separately from the Proceedings to expedite circulation Additional copies of this panel discussion are available upon request The annual meeting of members is one of the most valuable services of Foundation menbership Accordingly the Proceedings should be examined carefully and routed to all interested persons within each member's organization New Members and Subscribers Latest additions to the Foundation's membership list are American Optical Company Van Cleef Bros. and Vanadium Corporation of America New subscribers are Fairfield Air Service Command Ohio Medical Supply Officer Ft Mason Cal Ministers Ministers Sante & B.E.
