他看到的是活的——他将其描述为“许多非常小的活体物，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.

其中最的一个“像梭子鱼穿一样穿（唾沫）。 ” 他在牙齿的牙菌斑中发现的东西 - “小物” - 是细菌。

Using microscopes of his own design that could magnify up to 270 times, he examined a drop of water from a nearby lake and found it teeming with tiny creatures he called' animalcules'.

他使用自己设计的放倍数高达 270 倍的显微镜检查了附近湖中的一滴，发现其中充满了他称之为“小物”的微小生物。
