Over the years, Leeuwenhoek had often examined the optic nerve in various animals, but he had not been able to examine other nerves in any detail. In this letter, Leeuwenhoek reported that he was finally able to examine nerves; he described the vessels and cavities in the nerves of the spinal cords of cows and sheep. He also observed the particles of fat between the nerves and membranes around the nerves.
