Wilder, Neural Terms. 229 



'chorda' or 'chorda dorsahs,' for the embryonic gelatinous 

 basis of the spine, adds another source of confusion Hkely to 

 arise from the use of the term 'spinal chord,' appUed to the 

 myelon, or albuminous contents of the spinal canal. "^ 



§52. In 1873 ('73, 306) Owen's examples oi ectogluieiis, 

 niesogluteiis and entogliiteus led me to propose the locative mono- 

 nyms ectopcctoralis and entopcctoralis for the two frequently 

 named muscles whose relative proportions in most mammals 

 are so misrepresented by the adjectives major and minor. 



§53. I have already ('85, c, 5 '90, g, 1) expressed my 

 sense of obligation to Owen's terminologic precepts and exam- 

 ples, and my regret that the limits of the article, "Anatomical 

 Terminology" (W. & G., '89) did not permit even more ex- 

 tended selections than are embraced among the "Aphorisms 

 respecting Nomenclature " therein. 



§54. II. 1880-1883. While preparing a [paper on the 

 brain of the cat ( '81, d) and (with S. H. Gage) a volume of 

 directions for laboratory work (W. & G., '82) I adopted from 

 Barclay ('03) the unambiguous toponyms (§9) dorsal, dorsad, 

 etc. ; replaced his mesion by meson, the direct paronym of iiiaov ; 

 added ectal, ental, etc.; and simplified some organonyms, espe- 

 cially muscular (W. & G., '82, 207) and neural ('80, /; '^\,b, d) 

 in the following ways : ( a ) Dropping unessential adjectives 

 {opticus from thalamus diwd chiasma); eponymic (§33) qualifiers 

 {yarolii, Reilii, Rolando); and generic nouns {corpus, mater, and 

 membrana ) from adjectives which were sufficiently distinctive 

 and could be used as substantives ( callosum, dura, vmcosa ) ; 

 (b) substituting prepositions for adjectives (e. g., postcommis- 

 su7'a for cojnmissura postcjior); (c) Replacing certain polyonyms 

 by mononyms more or less nearly akin thereto ( e. g. , lamina 

 terminalis hy terniay, and(d) Abandoning the anthropotomic 

 misnomers of the encephalic cavities in favor of mononyms co- 



• The foregoing first appeared half a century ago ; the mononym myelon was 

 employed consistently by Owen, and on at least one occasion by his rival, Hux- 

 ley ('72, 65). These facts should secure for it the consideration due to high 

 authority and moderate antiquity, and forestall any hasty proposition to employ 

 it in a different sense.
