I n this article by R. R. Remick and C. J. Geankoplis [IKD.ENG.CHEN.,F U N D ~ M 9,206 . (1970)], eq 2 should be

I n this article by W. B. Krantz and D. T. Wasan [IND. ENG.CHEW,FUNDAM. 10, 424 (1971)] there is a n error in eq 22 on p 426. Equation 22 should read

On p 208 in the right column, the last sentence of the first paragraph should read : “At high pressures the binary curves differ by a maximum of +30 and -11% from the ternary curve.” I n Figure 2, the line for the binary A-C should be drawn so it is 1% below the ternary line a t 0.1 a t m and 11% below a t 100 atm. The heading in Table I1 for the flux of C should be ATc/ ( P I R T L ) .
