Wilder, Neural Terms. 251 



to me dates back a hundred and fifty years. In the " Medical 

 Dictionary" of James (1743), in the article "cerebrum", occurs 

 the following sentence : "The superficial vessels of the cerebrum 

 are lodged between the two laminae of the pia." 



§118. The employment of the mononymic feminine ad- 

 jectives as substantives, and of the secondary adjectives de- 

 rived therefrom, has now become so general ^ that the matter 

 would hardly need discussion but for the reactionary attitude of 

 the German committee. Yet this attitude is really not main- 

 tained consistently. Cornea is a feminine adjective. So is sclera. 

 In aracJinoidea eficepliali the feminine adjective is used as a noun. 

 Miiscidaris viucosae and tela siibimicosa are warrants for mucosa, 

 etc. Finally, although the useless noun is retained in dura 

 mater spinalis and filum durae matris spinalis, the very next 

 terms in their list, cavum cpidurale and cavum subdurale, are indi- 

 rect and probably unintended, yet none the less complete, pre- 

 cedents for dura pure and simple, and for the substantive em- 

 ployment of any and all feminine adjectives whatsoever. 



§ 1 1 9. EPIPHYSIS vs. corpus pineale.-Wis, regards epiph- 

 ysis SiS a " generelles Wort" ('95, 163) and the ancient dionym 

 is adopted by the German committee.^ My own earlier preference 

 was for conamim, as stated in §68. I now realize the desirabil- 

 ity of the verbal as well as the topographic correlation with 

 hypophysis zxiA parapJiysis, and the inutility of maintaining in all 

 cases the rigid doctrine of 187 1 i^^]). 



§120. FISSURA CENTRALIS vs. sidcjis centralis (or 

 fissura or sidcus Rolando^. — By comparison of the three columns 

 it will be seen that two distinct points are concerned, involving 

 respectively the generic and the specific names of this feature of 

 the lateral aspect of the cerebrum. If eponyms or personal 

 names are to be abandoned, as decided by the German commit- 



^ In Foster's Medical Dictionary, dura and pia, dtiral and pial, are major 

 headings, dura mater and/m mater being merely synonyms. 



2 In the earlier publication {Science, July 17, 1896, p. 71) of the report of 

 the Neurological Committee, the date, iSgj, after epiphysis would indicate its 

 adoption by the Germans. That was an error for which I must be held respon-. 

 sible, and which was corrected as soon as possible after it was noted ; '96, b..
