These end-organd are at once protective to the deli- cate nerves which terminate in them, and serve to convey to the latt^er peculiar impressions which are widely different in most in- stances from those resulting from the direct contact of the nerve with the foreign body. All are ac- quainted with the fact that, when IJo. of Vater (After Bnw). Flo. « (oorpuMlM) of Kiwue (after Ludden). A, from conjunctiva of man: B, from conlunctiTact calf.

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
