e professor said solemnly, is preferred to German
silver because it has a lower coefficient of resistance by changes of
temperature. The platinoid wire is insulated and the covering of silk
that insulates it is wound on the ebonite bobbins just where my finger
is. If it were wound single an extra current would be induced in the
coils. The bobbins are saturated in hot paraffin wax...

A sharp Ulster voice said from the bench below Stephen:

--Are we likely to be asked questions on applied science?

The professor began to juggle gravely with the terms pure science and
applied science. A heavy-built student, wearing gold spectacles, stared
with some wonder at the questioner. Moynihan murmured from behind in
his natural voice:

--Isn't MacAlister a devil for his pound of flesh?

Stephen looked coldly on the oblong skull beneath him overgrown with
tangled twine-coloured hair. The voice, the accent, the mind of the
questioner offended him and he allowed the offence to carry him towards
wilful unkindness, bidding his mind think that the student's father
would have done better had he sent his son to Belfast to study and have
saved something on the train fare by so doing.

The oblong skull beneath did not turn to meet this shaft of thought and
yet the shaft came back to its bowstring; for he saw in a moment the
student's whey-pale face.

--That thought is not mine, he said to himself quickly. It came from
the comic Irishman in the bench behind. Patience. Can you say with
certitude by whom the soul of your race was bartered and its elect
betrayed--by the questioner or by the mocker? Patience. Remember
Epictetus. It is probably in his character to ask such a question at
such a moment in such a tone and to pronounce the word SCIENCE as a
monosyllable.

The droning voice of the professor continued to wind itself slowly
round and round the coils it spoke of, doubling, trebling, quadrupling
its somnolent energy as the coil multiplied its ohms of resistance.

Moynihan's voice called from behind in echo to a distant bell:

--Closing time, gents!

The entrance hall was crowded and loud with talk. On a table near the
door were two photographs in frames and between them a long roll of
paper bearing an irregular tail of signatures. MacCann went briskly to
and fro among the students, talking rapidly, answering rebuffs and
leading one after another to the table. In the inner hall the dean of
studies stood talking to a young profe
