Although he himself could not draw well, he hired an illustrator to prepare drawings of the things he saw, to accompany his written descriptions. Compared to modern microscopes, it is an extremely simple device, using only one lens, mounted in a tiny hole in the brass plate that makes up the body of the instrument. Delft, where he spent the rest of his life. Che continued his observations until the last days of his life. Che discovered blood cells, and was the first to see living sperm cells of animals. His researches, which were widely circulated, opened up an entire world of microscopic life to the awareness of scientists. However, because of various technical difficulties in building them, early compound microscopes were not practical for magnifying objects more than about twenty or thirty times natural size. I found floating therein divers earthy particles, and some green streaks, spirally wound serpent-wise, and orderly arranged, after the manner of the copper or tin worms, which distillers use to cool their liquors as they distil over. I have thought it my duty to put down my discovery on paper, so that all ingenious people might be informed thereof. I notice resides in me more than in most other men. I then most always saw, with great wonder, that in the said matter there were many very little living animalcules, very prettily a-moving. In structure these little animals were fashioned like a bell, and at the round opening they made such a stir, that the particles in the water thereabout were set in motion thereby. Leeuwenhoek and is thought to have been a friend of his. Leeuwenhoek learned to grind lenses, made simple microscopes, and began observing with them. Leeuwenhoek looked at animal and plant tissues, at mineral crystals and at fossils. Leeuwenhoek soon became famous as his letters were published and translated. Leeuwenhoek succeeded in making some of the most important discoveries in the history of biology. London, describing what he had seen with his microscopes -- his first letter contained some observations on the stings of bees. Moreover, the other animalcules were in such enormous numbers, that all the water. Most of his descriptions of microorganisms are instantly recognizable. Russia, and he continued to receive visitors curious to see the strange things he was describing. The list of his discoveries goes on and on. The specimen was mounted on the sharp point that sticks up in front of the lens, and its position and focus could be adjusted by turning the two screws. These were much more similar to the microscopes in use today. This would have been enough to exclude him from the scientific community of his time completely. What further distinguished him was his curiosity to observe almost anything that could be placed under his lenses, and his care in describing what he saw. Wren, and other scientific luminaries of his day -- although he never attended a meeting.
