 A- long as the stomach ha- a vertical position, its mo.-ntri-y is a 

 vertical lamella, which stivu-lu's from the vertebral column (fig. 164) 

 din c-tly to the greater curvature, that is still olinvtol backward 

 [dorsad J. But in consequence of the torsion it becomes greatly 

 >ti ti lied and enlarged, because its attachment to the stomach must 

 follow all the displacements of that organ. From its origin at the 

 vertebral column, it therefore now betakes it>-lt t> tho 1, ft and 

 downward to become attached to the grea iture of the 



stomach ; it assumes a shape and position of which the reader will 

 easily form a correct idea if he mentally combines the diagram of
