FURTHERINVESTIGATIONS OF THESPECIALSENSEORGANS. DR. MAX A. GOLDSTEIN.
All of the organs of special sense—sight, hearing, taste and smell are but modifications of the sense of touch.
In the antennae of various classes of insects there is conclusive evidence that they function as olfactory as well as tactile organs, and I believe that they serve also as organs of hearing. This observation is one of the pivotal points in the physiologic and structural plan of the correlation of the sense organs.
The sense of touch seems to be most generally distributed, and from this sense the other senses appear to have been developed in most cases.
In the lower order of animals the special sense organs are not usually especially distinguishable one from the other, and in some instances the eminent scientists who have engaged in this delicate research conclude that the same nerve may be
