If however the living fibre be examined in the same way, it is fomid that nearly the whole of it is doubly refracting, the singly refract- ing substance appearing only as a meshwork with long parallel meshes corresponding to the muscle prisms. In short, in a living fibre the muscle prisms are anisotropous, the sarcoplasm isotropous. When a muscle-fibre contracts, there is an apparent reversal of the situations of the light and dark stripe
