These are but extreme and obvious cases in which na- ture has separated for us two histological elements and two processes, which are elsewhere confounded toge- ther. , â â "''â 'â ' â â¢â 'â ^' ' â ' 'â ' ⢠'â ' "â â â â 'â " One of the most com- plicated of tissues is striped muscle, yet the true homology of its elements seems to us to become intelligible enough upon these principles. Dr. Hyde Salter has pointed out, that in the tongue the muscles pass directly into the bundles of the submucous connective tissue which serve as their tendons. We have figured such a transition in fig. 6. The tendon A may be seen passing insensibly into the I.
