Other histologists have noticed this same arrange-ment in other sensory corpuscles, and Ruffini noted itaround Meissners corpuscles (fig. 31). All sensory corpuscles of the skin, therefore, havetwo kinds of fibres : one central and the other peri-pheral, the latter encircling the former in an irregularmanner. Ruffini concludes from his own histological observa-tions and those of his predecessors, that, in addition.

We are therefore inclined to think ^ that an irritationof the nerve-triinlv in the wound is transmitted by thecentrifugal fibres to the sensory corpuscles of the corpuscles being continually irritated in tliismanner, woTild cause the intense pain which occurs attimes spontaneously, and at others is due to externalcauses, such as contact, jarr
