Relations of isotropous to anisotropous layers in striped muscle : — 
Provisional conclusions : the isotropous layers retreat into the anisotro- 
pous; this retraction is alone sufficient to accouut for muscle contraction; 
there is a certain amount of positive evidence tendiug to show that the 
anisotropous layer is a mass of nuclear substance ; Bernard (35).
