These tastes he had kept up from boyhood; there was something pathetic in the persistency with which he clung to the pretence of serious study, though the physical fatigue which possessed him during his few hours of freedom would in any case have condemned him to mere trifling.

Often he came upstairs, lit his lamp, and sat for a couple of hours doing nothing more than play with his instruments, much as a child might; at other times a sudden revival of zeal would declare itself, and he would read and experiment till late in the night, always in fear of the inevitable lecture on his reckless waste of lamp-oil.

In the winter time the temperature of this garret was arctic, and fireplace there was none; still he could not intermit his custom of spending at least an hour in what he called scientific study, with the result that he went to bed numbed and shivering.

It was but another illustration of possibilities rendered futile by circumstances.

It was more than likely that the man might, with fair treatment, have really done something in one or other branch of physics.
