§ 126. (a) The internal oblique muscles of the eye, 

 occwpying the same relative position as in the snake, 

 are,frstqf all, and fundamentally connected with the 

 ophidian spine. They accept the additional connec- 

 tions as they form, and, finally, by the rather extensive 

 movement of the digastrics and the neck, the head joint 

 being the centre, the shoulders and lower jaw are ad- 

 justed with them, and the bi-composite spine is formed. 

 This is the course for what we consider the funda-
