movement with the right posterior action the 

 equalization of the sockets must be its final ac- 

 tion. But, in the first case, though the left ante- 

 rior line would be reduced as the right condyle 

 came into place, by the drawmg of the right sterno- 

 mastoid at the right upper corner of the sternum, 

 a further and separate action of the right posterior 

 line would be required to give full equahzation to 

 the alternate left posterior line and carry out the 

 collateral drawing from the pelvis. And in the 

 same way, in the second case, induction from the 

 right posterior line being finished by equalizing the 

 position of the left socket with the right one and 

 drawing on the left shoulder-blade, a separate ac- 

 tion of the left anterior Hue would be necessary to 

 carry out the drawing of the right alternate line 

 from the head. 



Fourth. — Although the forcing tractions may be 

 begun at any point, and their relations afterwards 

 adjusted, yet the regular succession, in order to a 

 smooth working, is to begin in any S with the point 

 of application, either of the anterior or posterior 

 line, and to continue that line through the forma- 

 tion of all the "spines" before the other line begins 

 by induction. 



Fifth. — In the equalizations, the new formations
