What he saw was alive—he described it as " many very little living animalcules, very prettily a-moving."

他看到是——他将其描述为“许多非常小物，非常漂亮地在移” 。

The biggest of which " shot through the water (or spittle) like a pike does through the water." What he had discovered in the plaque from his teeth—the " animalcules" —were bacteria.

其中最大“像梭子鱼穿过水样穿过水（或唾沫）。 ” 他在牙齿牙菌斑中发现东西 - “小物” - 是细菌。

And it may be asked what advantage, as far as we can see, would it be to an infusorian animalcule—to an intestinal worm—or even to an earth-worm, to be highly organised.

可能有人会问， 就我们所知， 高度组织化对纤毛虫——对肠道蠕虫——甚至对蚯蚓有什么好处。
