This continuing programme of research has revolutionised our understanding of the dawn of experimental biology. A series of specimens, sent from the Netherlands to London during the 1600's, were discovered amongst the files of the Royal Society's archives. Microscopical examination shows they were as well prepared as many modern specimens. The image of blood cells, for example, reveals details comparable with the results a modern microscope might reveal. Click here to see the microscopes; there is also an extensive Leeuwenhoek bibliography on this subject.
Leeuwenhoek's specimens, intact after over three centuries, were found still attached to the original letter
Sections of cotton seeds, safely stored in paper envelopes, attached to one of his letters to the Royal Society.
Three samples of aquatic algae had been dried to a papery film. The material could be reconstituted and studied.
