Abstract

We find a correction is necessary in the last sentence on page 625 of our article entitled "An Analogof Vitamin B12" (Science, 113, 625 [1951]).

In our original this sentence reads:

The thiocyanate analog and vitamin B12a when testedby the L. lactic (A) and the L. leichmannii "unprotected" (B) titrimetric assay methods (6) also respondin a like manner, distinct from vitamin B12.

Please publish the following correction:

The thiocyanate analog and vitamin B12a, when testedby the L. lactis (B) and the L. leichmannii "unprotected" (A) titrimetric assay methods (6) also respondin a like manner, distinct from vitamin B12.

This will also necessitate the transposition of theheadings "A" and "B" in Table 1 on page 626.
