We are grateful to the sharp-eyed reader who picked out the mistake in our article, "Fifty-Year Trends in the Chemical Industry" (J. Chem. Educ. 1999, 76, 177-189). The correct caption for Figure 2 on page 179 of the February 1999 issue is:

Figure 2. Schematic representation showing the snugfit of an n-butylammonium ion in a channel of a ZSM-5 zeolite. The zeolite crystal is made up of Si and Al ions (both shown in silver) linked together by oxygens (red). The nitrogen atom (blue) of the organic molecule is ionically bound to an anionic site in the channel wall.

Supplement
The corrected caption for Figure 2 is can be accessed as a pdf file using Acrobat Reader.
