It may be noticed that in all tbese cases the nerve loses its non-essential parts before entering the corpuscle. the epithelium is removed, as by a blister, we no longer possess tactile sensibility of the usual kind, and experience pain on contact with objects; in a word, the series of connections neces- sary to a sense-perception is broken at the commencement. Seeing that all the end-organs on the surface of the body have a common origin morphologically, it would be reasonable to expect that the senses would have much in common, espe- cially when these organs are all alike connected with central nervous cells by nerves. As a matter of fact, such is the case, and in every instance we can distinguish between sensory im- pulses generated in the end-organ, conveyed by a nerve inward, and those in the cells of these central nervous systems, giving'.
