By their aggregation around the pylorus, they constitute the sphincter {ov pyloric valve) which envelops that orifice. The deep plane (Fig. 261, a), like the first, is specially destined for the left sac, and cannot be properly studied except in an averted stomach deprived of its mucous membrane. Much thicker than the superficial plane, it yet, in its general arrangement, much resembles it. Thus, its fasciculi present loops which embrace the left cul-de-sac, and the extremities of which are lost on the faces of the organ, where some of them become continuous with the circular fibres. The loops nearest the oesophagus embrace the stomachal opening of that canal like a cravat. It is to be remarked that the fibres of this deep layer intersect those of Fig. 261.
