Moynihan, seeing the professor bend over the coils, rose in his bench and, clacking noiselessly the fingers of his right hand, began to call with the voice of a slobbering urchin.

-----Please teacher! This boy is after saying a bad word, teacher.

----Platinoid, the 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 heavybuilt 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 twinecoloured 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 wheypale face.
