The c u t below represents one of three decorative panels set in the limestone facing just above the main entrance to the George Eastman Research Laboratories for Physics and Chemistry a t the Massachusetts Institute of Technology. These plaques symbolize the spirit and purpose of the laboratories. The likeness of the young scientist, van't Hoff, recalls the early age a t which he announced the principle of molecular asymmetry. I n the cutting of the panel the artist was guided by models constructed by Dr. Avery A. Ashdown of the Massachusetts Institute of Technology. The bronze plaque reproduced a t the left is from the collection of Dr. Lyman C. Newell, t o whom we are also indebted for the photograph of the panel.
Correction THE photograph of the van't Hoff panel which appeared on the frontispiece page of the June JOURNAL should have been credited to Dr. Avery A. Ashdown, though it came to us through Dr. Newell's hands. We are indebted to Dr. Tenney L. Davis for the information that the bronze plaquette bearing van't Hoff's likeness is a reduced replica of a marble basrelief in the corridor of the van't Hoff Laboratorium at Utrecht.
