account of it to Guillaume; it would interest him."

At a glance from his brother, Pierre accepted the invitation. Then,
Bertheroy having gone, he recounted all he had learnt during the
afternoon, how Salvat was suspected, and how the investigating magistrate
had been put on the right scent. And at this news, intense fever again
came over Guillaume, who, with his head buried in the pillow, and his
eyes closed, stammered as if in a kind of nightmare: "Ah! then, this is
the end! Salvat arrested, Salvat interrogated! Ah! that so much toil and
so much hope should crumble!"

IV. CULTURE AND HOPE

ON the morrow, punctually at one o'clock, Pierre reached the Rue d'Ulm,
where Bertheroy resided in a fairly large house, which the State had
placed at his disposal, in order that he might install in it a laboratory
for study and research. Thus the whole first floor had been transformed
into one spacious apartment, where, from time to time, the illustrious
chemist was fond of receiving a limited number of pupils and admirers,
before whom he made experiments, and explained his new discoveries and
theories.

For these occasions a few chairs were set out before the long and massive
table, which was covered with jars and appliances. In the rear one saw
the furnace, while all around were glass cases, full of vials and
specimens. The persons present were, for the most part, fellow _savants_,
with a few young men, and even a lady or two, and, of course, an
occasional journalist. The whole made up a kind of family gathering, the
visitors chatting with the master in all freedom.

Directly Bertheroy perceived Pierre he came forward, pressed his hand and
seated him on a chair beside Guillaume's son Francois, who had been one
of the first arrivals. The young man was completing his third year at the
Ecole Normale, close by, so he only had a few steps to take to call upon
his master Bertheroy, whom he regarded as one of the firmest minds of the
age. Pierre was delighted to meet his nephew, for he had been greatly
impressed in his favour on the occasion of his visit to Montmartre.
Francois, on his side, greeted his uncle with all the cordial
expansiveness of youth. He was, moreover, well pleased to obtain some
news of his father.

However, Bertheroy began. He spoke in a familiar and sober fashion, but
frequently employed some very happy expressions. At first he gave an
account of his own extensive labours and investigations with regard
