Pages 877-1032
About the Cover:

Spikes of different heights form in an aqueous ferrofluid depending on the distance between the ferrofluid and a magnet. A video of this dramatic sequence can be found as a supplement on JCE Online at http://JChemEd.chem.wisc.edu/Journal/Issues/1999/Jul/abs943.html. Patricia Berger, Nicholas B. Adelman, Katie J. Beckman, Dean J. Campbell, Arthur B. Ellis, and George C. Lisensky discuss the preparation and properties of an aqueous ferrofluid on pages 943-948.
