Antonie van Leeuwenhoek

I have had a great many people come to me, some of whom were very learned, and others not so learned, but all of them were very desirous to see the things I had discovered.

I have made a discovery that is very strange and wonderful, and that is, that there are living creatures in water, which are so small that they cannot be seen with the naked eye.

I have often observed that the smaller the creature, the more numerous they are.
