    épithélial cells, acid or pariétal cells, red blood corpuscles, and connective tissue cells. The glandular structure beneath the mass on either side is greatly disarranged, and has lost the glandular outline. Fig. 12. — (Low power). Stomach of dog. More advanced stage, with necrosis almost reaching the muscularis, exposing a small blood vessel (hæmatoxylin & orange G). The épithélial cells (chief cells) are scattered irregularly throughout the stroma. They show marked degenerative changes; are small and irregular in shape; their protoplasm is vacuolated, and the cell body distorted or compressed, while their nuclei are small, elongated, distorted and pale, or refuse to stain. These chief cells seem to be crushed out of existence largely by the acid or pariétal cells. The latter are so numerous that they almost replace the entire field of the mucosa and are proli- ferating in large numbers. The prolifération of the acid cells is a marked feature in ail these sections. Mitotic figures are very nu- merous; many of the cells contain two nuclei. They vary in size, being sometimes two and four times their natural size. Hand in hand with prolifération of these cells there are also degenerative
