face epithelium and gastric glands. The persistent connective tissue stroma 

 was covered with fibrin, and necrotic areas were noted. 



Moehl ('22) observed frequent gastrointestinal disorders in underfed horses.

Figs. 82 to 84. — From sections through the pyloric region of albino rats. Bouin's fixation; 

 hematoxylin-eosin stain. X50. l.m., longitudinal muscle layer; cm., circular muscle; s.m., 

 submucosa; m.m., muscularis mucosae; m.p., membrana propria; gl.g., gastric glands; p.c, 

 parietal cell; su.e., surface epithelium; a, necrotic surface membrane; ed., edemic spaces.

Fig. 82 shows a section of the pyloric region in a normal initial control rat 11 days old; 

 body weight, 9.5 g; stomach weight, 0.0569 g. Fig. 83 represents the stomach struc- 

 ture in a final (age) control, full-fed to 37 days of age; body weight, 68 grams; stomach weight, 

 0.541 g. Fig. 84 shows the pyloric stomach in a rat underfed from birth to 39 days of age; 

 body weight 9.66 g; stomach weight, 0.151 g. Note the necrotic surface membrane 

 (a), the atrophic glands and edemic interglandular spaces (ed), and the pycnotic condition of 

 the nuclei in the mucosa. 



Moulton, Trowbridge and Haigh ('22a) found subnormal weight of the 

 stomachs in steers on low planes of nutrition.
