Discussionion of Leeuwenhoek's ideas about the structure and action of muscle fibres and tendons from the leg of a mouse.

Illustration of a model of Leeuwenhoek's assumed spiral contraction.

In order to gain a better understanding of the extension and contraction I have wound a little piece of copper wire around a writing-pen; and just as it had been removed from the writing-pen I have had it drawn.
