Each shell, in the process of rolling from one hand into the other, exposed its lateral surface and was closely scrutinized for scratches, oil dents, stains, and other defects. The good ones were taken in the right hand and dropped into a pocket at the right side of the table, through which they fell into a box below.

The defects to be detected were often so minute as to be indistinguishable to any but the best of eyes. It took the experimenter almost a minute to see one of the most common defects which these girls were required to notice in an instant. Any weakness of the eyes or marked difference between the two would be likely to show bad results in the inspection. 2. Keen visual discrimination. Good eyesight is not sufficient. The inspector, looking at a whole handful of shells, must, with a few glances, be able to recognize those which are defective and remain oblivious to those which are not. 3. Quick reaction; that is, the ability to extract, as quickly as seen, the defective shell and toss it into the appropriate box. 4.
