 when commencing with the ophidian S, in pretty 

 full detail, but as was said, it is not necessary in

 produces the other, if allowed. 



Tico chief points are to he kept in mind, viz., that 

 the movement of the cross-line ends more particularly 

 changes the curvatures, and that the focus of this 

 movement must he maintained hetween the upper and 

 loicer lung lohes, that is, at the centre of the ophidian

 end of the sternum, etc. 



§ 167. No. 1.— For " setting-up " with the {left)
