HI Frank great stuff speaking of early Mixter I have a 15th printing circa Oct, 1943 and my question is regarding the dip table on the inside cover, part of Table A . If you have reference to it I noticed with much confusion that most of the correction is positive. I tried to find the explanation but I seem to be missing something. Your enlightment would be greatly appreciated thanks much. > Jeremy, you wrote: > "Funny thing about that, it was my textbook for 3 semesters of CelNav in > college." > > LOL.
