EXPLANATION OK FIGUKK 



1 Nerve distribution in the right membrana tyinpani of man. The pars flaccida 

 with the head of the malleus has been removed. The nerves were stained with 

 methylene blue and the specimen was mounted in Canada balsam. During the 

 process of mounting the manul>riui mallei was twisted so that the processus later- 

 alis (/^/.) is tilted posteriorly. The main nerve trunk {n.t.m.) together with the 

 artery (a.m.t.) is seen entering over the posterior superior cjuadrant. Not all the 

 peripheral nerves {p.n.) took up the dye but a sufficient number to give an ade- 

 (|uate representation of their mode of distribution at the limbus.
