the limbs, their segments and joints^ all were mononyms (§ 15). 

 With most were given the singular and plural nominative and 

 genitive. Two, omozonc and ischizone, were Anglicized (paro- 

 nymized). The designation of the fingers by the adjectives, in- 

 dex ^ niediiis, annula} is ^.nd inininmSy without preposing the sub- 

 stantive digihis, recognized Contextual Explicitness (§ 26) and 

 the validity of adjectival nouns (§ 117). 



§51. Then, as now, the most desirable (yet not absolutely 

 essential [§§ 67-70] ) attributes of technical terms seemed to 

 me (i) Classic Derivation, (2) Capacity of Inflection. But 

 both these had been adumbrated long before by Barclay ('03) 

 and Whewell ('40), and distinctly enunciated by Owen ('46, 171) 

 in the immortal paragraph wherein myelon was proposed : 



" The fore part of the neural axis * * is called the brain or 

 encephalon ; the rest I term inje/on, (Greek iweXuq marrow). As 

 an apology for proposing a name, capable of being inflected 

 adjectively, for a most important part [see W, & G., '89, §48] 

 of the body which has hitherto received none, I may observe 

 that, so long as the brief definitions, 'marrow of the spine,' 

 ' chord of the spine,' are substituted for a proper name, all pro- 

 positions respecting it must continue to be periphrastic, e. g., 

 ' diseases of the spinal marrow,' ' functions of the spinal chord,' 

 instead of myelonal [myelic] ^ diseases, myelonal functions ; or 

 if the pathologist speaks of 'spinal disease,' meaning disease 

 of the spinal marrow, he is liable to be misunderstood as refer- 

 ring to the disease of the spinal or vertebral column. But were 

 the anatomist to speak of the canal in the spinal marrow of fishes 

 as the ' myelonal canal ' he would at once distinguish it from 

 the canal of the spinal column. The generally accepted term 



* Among the few new terms were otjios, for shoulder-joint, and omozona and 

 ischizona, for shoulder-girdle and pelvic-girdle respectively. They still seem to 

 me preferable to the " Articttlatio humeri,'''' " Cingidum extremitatis superioris''^ 

 and " Cingulum extremitatis inferioris''^ of the German list. 



^ On several previous occasions ('85, 354; '85, 12; '89, 531) I have shown 

 that analogy with words like atigel 2.x\A. angelic (from ayytXo'z) calls for wj'^/and 

 myelic as the English nominative and adjective of myelon ; myelonal \% clumsy, 

 and analogy would involve the replacement of encephalic by encephalonal.
