beheld, not the haggard face of a man who daily risked the possibility
of being awarded the O.B.E., but the calm and smiling countenance of
one who had succeeded where other scientists, even of Anglo-American
reputation, had failed.

In an awed silence this remarkable man placed on the table a dish,
somewhat like a soup-plate in appearance, and carefully removed its
glass cover.

"In this dish, gentlemen," said the Professor, "we have the Agar-Agar,
which is without doubt the best bacteriological culture medium yet
discovered and is especially useful in growing a pathogenic organism
such as we are about to test this afternoon."

Then taking a glass rod, to the end of which was attached a small
piece of platinum wire, the lecturer proceeded to scrape a little
of the growth from off the Agar-Agar. Having done this he quickly
deposited it in a test-tube half full of distilled water, which
he then heated over a Bunsen burner. Finally, with the aid of a
hypodermic syringe, a little of the liquid was injected into two
sleepy-looking guinea-pigs, and with bated breath the result of the
test was awaited.

Suddenly, without any warning, the two little animals rose on their
hind legs and violently clutched each other by any part of the body
on which they could get a grip. Before the astounded gaze of the
onlookers they swayed, nearly fell, then went round in circles, at the
