"The bulge" is not found consistently, in contrast to the observations of Stohr and F. Pinkus.

Irregularities of the outer sheath are seen in association with the point of attachment of the muscle of hair erection, i.e., midway between the bulb and the junction of the sebaceous gland with the follicle.

The authors did not find "the bulge" because they did not realize that the irregularities of the outer sheath at the site of attachment of fascicles of hair arrector muscle were, in reality, bulges.
