Material-Rattus losea (SWINHOE), one of the most popular field rats in Formosa. Method-Studied the distribution of the parietal cells quantitatively by total serial sections of stomach. Observation-In fundus gland area the parietal cells are distributed uniformly as the number of 40 to 50 on the unit length. Used 0.08mm as the unit length. Pyloric gland lacks the cell absolutely. The fundus gland area shows a triangle with the greater curve as the base and area 5 as the apex. The cell decreases in its number to 0 rapidly near the apex but gradually near the base, and changes into pyloric gland area. No difference was observed between male and femal adult rat. The parietal cell begins to differentiate at about one week after birth and makes area 10 or 11 as its increasing center. Then one expands to pylorus along the greater curve, and the other to cardia along the margin of the oesophageal part. Male reaches adult condition at 130mm head and body length and femal, 120mm. The number of the cell decreases in various degrees and manners in the stomachs of old rats, longer than 160mm.
