The fibres at once form a little flatmuscle, rather longer in shape than the fish from which.

This tendon, long and narrow,passes directly down the postero-internal aspect of theleg to become inserted into the dense fascia covering thetibial cartilage at its supero-internal angle. Professor Mivart says that in Ornithorhynchus thismuscle is inserted into the astragalus. And that fur-ther, in Nycticehus it has lost its tibial attachment,is entirely muscular, and blends with the same author also informs us that in the Agoutiit arises from the tibia only, wdiile it is wanting in thePig, Hyaena, Seal, and others {Elem. Anat., p. 354).I present these comparative notices of such musclesas the soleus in others of the Vertebrata in order thatwe may have before us at least short histories of themuscle i
