Dan Yoshimoto asks about Ward's Natural Science Establishment in Rochester,
New York. Ward's is at least a century old and is still one of the world's
leading companies in the scientific supply business. They received previous
attention on Conch-L as suppliers of chipboard trays. Ward's has a web site
and a lively awareness of their own history, and might respond to an
inquiry as to the date of the catalog.
