He did not long remain there, and, on coming out into the office where we were waiting, brusquely asked, "Are you the persons who want to measure heads?
Well, they are waiting for you out there in the corridor; why don't you go to work ?" Seizing our instruments, blanks and camera, we hurried to the corridor and began operations.

Three or four were measured in quick succession; then, when I cried, "_Otro_" (another), the _jefe's_ eyes began to bulge.

That one measured, and another called for, he seemed half-distracted; desperation seized him; as he faintly repeated "_Otro_" he looked wildly around in search of subjects and it was plain that he had not begun to realize what demands we planned to make upon him.
Before the noonday rest, we had measured fourteen subjects, but the _jefe's_ personal interest had ceased, and he had completely disappeared from the scene of action.

When we returned at three o'clock to resume work, only the guards were there to help us.

One and another subject, invited to be measured, showed no interest in advancing science.
