However, concentrations of Pacinian corpuscles (detecting deep pressure) and Ruffini's corpuscles, which responding slowly to sustained pressure and tangential forces, are thought to be present in much of separating fascia, for example, in subcutaneous tissue.
Also both areas lack hair follicles, sebaceous glands and melanocytes but are provided with abundant sweat glands and pacinian corpuscles. This provides optimal sensibility and moisture.

The tip of the trunk contains two kinds pressure-sensitive nerve endings Meissner's corpuscles that detect infrasonic vibrations, and Pacinian corpuscles that respond to vibrations with slightly higher frequencies.
Accordingly, on page 36, at the bottom of the left column, the last two lines should be changed to read as follows: "...and joint receptors (Golgi ligament endings, Ruffini endings, Pacinian corpuscles, and free...."
