A SLIP UNDER THE MICROSCOPE

It was just the kind of thing that the botanical professor was always doing. Like the income tax, it offered a premium to the cheat.

The professor's reason for decreeing that the slip should not be moved depended on the fact that the object he wanted identified was characteristic of a certain tree stem. In the position in which it was placed it was a difficult thing to recognise, but once the slip was moved so as to bring other parts of the preparation into view, its nature was obvious enough.

Hill came to this, flushed from a contest with staining re-agents, sat down on the little stool before the microscope, turned the mirror to get the best light, and then, out of sheer habit, shifted the slip. At once he remembered the prohibition, and, with an almost continuous motion of his hands, moved it back, and sat paralysed with astonishment at his action.
