INC.___LAKE__CHARLESit_ LA TO: Lloyd McCain DATE: FROM: SUBJECT: February 4, lj*93 Howard Duhon*ft Vinyl Chloride Test The class you instructed on 1-29-93 had 49 names on the sign up sheet, but "only 48 test. After checking each one off one by one it was discovered that the one missing was yours. I need for you to take the 1993 Vinyl Test and send it in to me. This is drawing a fine line, but unless you put the test together, I need a copy even for the instructor. SL 074670
