Transverse section of the wall of a dog's stomach. (After Mall. ) On the right the tunics are super- 

 imposed, on the left the vessels and vascular plexuses are shown. (From Poirier et Charpy, Trait6 

 d'Anat. hum., Paris, 1901, 2 ed., t. iv. p. 229, Fig. 122. ) 



Open the stomach along its greater curvature, spread it out, 

 pin it down upon a cork dissecting tray, and study its coats and 

 the valve and muscle derived from them. (Cf. Fig. 264.) Also 

 consult " The Vessels and Walls of the Dog's Stomach," by 

 Professor Mall, in Johns Hopkins Hosp. Reports, vol. i. p. 1.
