Conjuration, sleight of hand, magic, witchcraft, were the subjects of the evening.

变戏法、掌中诡计、魔术、巫术，是当晚的主题。

And it reads like a how-to manual of conjuration.

读上去像是召唤术的学习手册一样。

But, if thou wear this form through mere passing conjuration, then resume thy former aspect!

但是，如果你只是通过短的咒语而穿上种形态，那么恢复你以前的样子吧！

Brooding over all these matters, the mother felt like one who has evoked a spirit, but, by some irregularity in the process of conjuration, has failed to win the master-word that should control this new and incomprehensible intelligence.

思索着所有， 亲觉得自己像是唤起了一个灵魂，但由于召唤过程中的一不规则， 未能赢得应该控制个新的、不可理解的智能的主词。
