They are most numerous in the summer months, disappearing almost entirely in
winter in the marine plankton, during which season we have only observed Tintinnopsis
nucula and T. ventricosa.

Many species are luminescent; notably, Tintinnus lususundae.

No fresh-water species of Tintinnidae have been reported up till now, so far as
the writer is aware, from British Columbia.

The following, however, are present in Lake Nipigon and occur in California, as
identified by Dr. S. A. Campbell, namely:

Codonellopsis cratera with its varieties laevis and reticulata, Tintinnus fluviatils
and Tintinnopsis cylindrica.

In Lake Nipigon they sometimes formed a considerable portion of the plankton.

In both fresh and salt-water they provide food for fish and other animals.

In a wireless talk the City Librarian of Nottingham said: ‘When Shakespeare
wrote “Friends, Romans, countrymen, lend me your ears,’ it may have been intelligent

Shakespeare’s words, “knock at your ear and beseech listening,” I invite your atten-

to be asked how the cinema affected the public libraries, and my reply was that the
movie-pictures could never take the place of the printed word—but that the subjects
filmed often directed picture-goers to our books. I am now asked about Broadcast-
ing; and my answer is that Broadcasting can never supplant libraries. Wireless will
never displace the use of books, any more than books will take the place of wireless.
The linking of one with the other is a great combination, and the Library Association
and the B. B. C. are doing all they can to co-operate in schemes throughout the
country, egy
