    • 1916, 丘浅次郎, 境界なき差別[1], 青空文庫:
      脊椎動物(せきついどうぶつ)には(からだ)中軸(ちゅうじく)脊骨(せぼね)があり、無脊椎動物(むせきついどうぶつ)にはけっして脊骨(せぼね)がないといえば、その(あいだ)境界(きょうかい)は、きわめて判然(はんぜん)しているごとくに(きこ)えるが、実物(じつぶつ)について調査(ちょうさ)すると、発生(はっせい)途中(とちゅう)一度脊骨(いちどせぼね)ができて、(のち)にふたたびこれを(うしな)うもの、わずかに脊骨(せぼね)痕跡(こんせき)のみを(ゆう)するものなどが、いくらもあって、けっして(あき)らかな境界(きょうかい)はない []
      Sekitsui dōbutsu ni wa karada no chūjiku ni sebone ga ari, musekitsui dōbutsu ni wa kesshite sebone ga nai to ieba, sono aida no kyōkai wa, kiwamete hanzen shite iru gotoku ni kikoeru ga, jitsubutsu ni tsuite chōsa suru to, hassei no tochū ni ichido sebone ga dekite, nochi ni futatabi kore o ushinau mono, wazuka ni sebone no konseki nomi o yūsuru mono nado ga, ikura mo atte, kesshite akiraka na kyōkai wa nai []
      If I said that vertebrates have a backbone along the central axis of their body and invertebrates never do, it would sound as if the boundary between them were very distinct, but if you examine actual specimens, there will be those that develop a backbone once during their ontogeny and subsequently lose it, those that have just a small vestige of a backbone, and many other such cases. There is by no means a clear boundary. []
