In the tongue of the frogthe muscular fibres (fig. 114) as they ap-proach the surface divide into numerousbranches, by which they are attached to theunder sm-f ace of the mucous membrane. Thesame thing has also been seen in the tongueof man and various animals: and the fil^res ofthe facial muscles of mammals dividein a similar manner where they fix them-selves to the skin (Busk and Huxley).
