But the word of mr costello was an unwelcome language for him for he nauseated the wretch that seemed to him a cropeared creature of a misshapen gibbosity born out of wedlock and thrust like a crookback teethed and feet first into the world , which the dint of the surgeon s pliers in his skull lent indeed a colour to , so as it put him in thought of that missing link of creation s chain desiderated by the late ingenious mr darwin 分娩时属逆产,足先露,且驼背188 。外科医用钳子在彼头盖上留下了明显痕迹。布卢姆遂联想到,彼即已故富于独创性之达尔文先生毕生探求不已之进化论中所谈之过渡生物189也。
