TitleUnpublished letter, 'On the structure of the ultimate fibril of the muscle of animal life' from Erasmus Wilson to Peter Mark Roget
Date5 June 1844
DescriptionUsing a powerful microscope, Wilson is able to make discoveries on the structure of the ultimate muscular fibril. He records his observations upon a specimen taken from the arm of a strong, healthy man immediately after its amputation. He finds each fibril to be composed of minute cells with flattened surfaces, arranged in a linear series, creating a uniform cylindrical shape.

Followed by one page of diagrams regarding the structure of the ultimate fibril of the muscle of animal life.
