Note 31 — V A NATIONAL LIBRARY SERVICE.

“Sometimes a discovery of vital moment lies concealed for many years in a little known periodical; the most striking recent case is that of Mendel’s experiments, now the inspiration of the most productive school of modern biology, described in 1865 in the periodical of a natural history society in Brünn but buried until 1900, when a happy chance revealed them.” Times, June 29, 1921—“Indexing of Technical Literature.”
