gustation manifest themselves in the primitive state. The sight of cruelty, the 

 sound of martial music, the odor of Limburger cheese, the taste of some extra- 

 ordinary viand, are facially expressed, and read off by the world as disapproval, 

 patriotic enthusiasm, repulsion, satisfaction. If, then, auditory, optic, and 

 gustatory nerves are capable of conveying an impression to the brain for record, 

 are they entitled to the designation " special sense " any more than is the facial, 

 which does its own work, and facially expresses to the world the recorded 

 experiences of all the so-called nerves of special sense ? Is not this nerve a 

 special sense nerve of facial pantomime ?

The Facial Nerve (Fig. 16): Its Dissection on the Face. Remove the 

 skin. Cut down through the parotid gland in the direction of the vertical line in 

 figure 1 2. It is necessary to go through about one-half of an inch of gland sub- 

 stance. Take the forceps, and find a nerve trunk about the size of a knitting- 

 needle. This will be the inferior division of the nerve the cennco-facial part. 

 Follow this branch up a little further, and, very deeply located, you will find the 

 main tnin/c of the nerve. From this you can trace out all the facial branches, 

 in this manner : Put a small piece of tape around the main trunk. Pull on this,
