In Sec. 178.3130(b), on page 364, in the second column, in the first line of number 2 under Alkyl mono- and disulfonic acids, correct ``be'' to read ``to'', and in the same column, at the end of the fourth paragraph, after the words ``such foods have a pH'', add the words ``above 5.0''. 2. In Sec. 178.3620(c)(3), on page 384, in the first column, in the first full paragraph, line 14, after the words ``Loosen the'' correct ``top'' to read ``topmost'' and add the following: * * * * * ``few millimeters of each adsorbent layer with the end of a metal rod before the addition of the next layer. Continue packing in this manner until all the 14 grams of the adsorbent is added to the tube. Level off the top of the adsorbent by pressing down firmly with a flat glass rod or metal plunger to make the depth of the adsorbent bed approximately 12.5 centimeters in depth. Turn off the vacuum and remove the suction flask. Fit the 500-milliliter reservoir onto the top of the chromatographic column and prewet the column by passing 100 milliliters of isooctane through the column. Adjust the nitrogen pressure so that the rate of descent of the isooctane coming off the column is between 2-3 milliliters per minute. Discontinue pressure just before the last of the isooctane reaches the level of the adsorbent. (Caution: Do not allow the liquid level to recede below the adsorbent level at any time.) Remove the reservoir and decant the 5-milliliter isooctane concentrate solution onto the column and with slight pressure again allow the liquid level to recede to barely above the adsorbent level. Rapidly complete the transfer similarly with two 5-milliliter portions of isooctane, swirling the flask repeatedly each time to assure adequate washing of the residue. Just before the final 5-milliliter wash reaches the top of the adsorbent, add 100 milliliters of isooctane to the reservoir and continue the percolation at the 2-3 milliliters per minute rate. Just before the last of the isooctane reaches the adsorbent level, add 100 milliliters of 10 percent benzene in isooctane to the reservoir and continue the percolation at the'' * * * * * 2.In Sec. 178.3910(a)(2) table, on pages 406 and 407, in the first column, under ``List of substances'', correct the second, third, and fifth entries to read as follows: * * * * * -Butyl--hydroxypoly(oxypropyl-ene) (CAS Reg. No. 9003-13-8) having a minimum molecular weight of 1000. -Lauroyl--hydroxpoly (oxyethylene) (CAS Reg. No. 9004-81-3) having a minimum molecular weight of 200. * * * * * alpha-Alkyl-omega-hydroxypoly-(oxyethylene) produced by the condensation of 1 mole of C12-C15 straight chain primary alcohols with an average of 3 moles of ethylene oxide (CAS Reg.
