78.In experiments，an injection of cytoplasm from dextral eggs changes the pattern of sinistral eggs，but an injection from sinistral eggs does not influence dextral eggs.

　　在实验中，用取自右旋卵子的细胞质进行的注射，可改变左旋卵子的模式；用取自左旋卵子的细胞质进行的注射却不能影响到右旋卵子。

　　然则，在所有这些被搬上银幕和舞台的改编作品中，没有任何一部作品能生动地再现《康乃涅克州的美国佬》结尾处的无政府状态。而在原作结尾处所描述的情节是，摩根历时三年之久苦心经营的进步事业被暴力推翻，他又重返于十九世纪，在由于他的那些有关吊桥和城垛的语无伦次的唠叨而被列为疯子之后，显然自杀身亡。
