But in the north, British ships eventually find the French fleet and completely destroy it. Napoleon and his army find themselves stuck in Egypt.

但在北方，英国船只最终发现了法国舰队并将其彻底摧毁。拿破仑和他的军队被困在埃及。

Nevertheless, until reading an able and valuable article in the " North British Review" (1867), I did not appreciate how rarely single variations, whether slight or strongly marked, could be perpetuated.

然而，直到读到《北不列颠评论》（1867 年）中的一篇干练而有价值的文章，我才意识到单一的变异， 无论是轻微的还是强烈的， 很少能永久保存下来。
