In the reaction from his first impulse of atonement, Lethbury noted with sharpened perceptions the effect of the change on his wife's character. He saw already the error of supposing that it could work any transformation in her. It simply magnified her existing qualities. She was like a dried sponge put in water: she expanded, but she did not change her shape. From the stand-point of scientific observation it was curious to see how her stored instincts responded to the pseudo-maternal call. She overflowed with the petty maxims of the occasion. One felt in her the epitome, the consummation, of centuries of animal maternity, so that this little woman, who screamed at a mouse and was nervous about burglars, came to typify the cave-mother rending her prey for her young. It was less easy to regard philosophically the practical effects of her borrowed motherhood. Lethbury found with surprise that she was becoming assertive and definite. She no longer represented the negative side of his life; she showed, indeed, a tendency to inconvenient affirmations. She had gradually expanded her assumption of motherhood till it included his own share in the relation, and he suddenly found himself regarded as the father of Jane. This was a contingency he had not foreseen, and it took all his philosophy to accept it; but there were moments of compensation. For Mrs. Lethbury was undoubtedly happy for the first time in years; and the thought that he had tardily contributed to this end reconciled him to the irony of the means.
