Abstract: Spleens in chickens from 4 days of incubation to 23 weeks of age were observed by means of quantitative histological methods with special reference to the development of the white pulp. The results obtained were as follows. The developmental process of the spleen in chickens was distinguished into 7 stages : 3 in the embryonic and 4 in the posthatching spleens. No development of lymphatic tissues was found in the embryonic spleens ; however, there were some in the posthatching spleens. The white pulp was divided into 4 tissue elements : periarterial lymphatic tissue (PAL), perivenous lymphatic tissue (PVL), periellipsoidal lymphatic tissue (PEL), and the germinal center. Out of 4 elements, the appearance time of PVL was the earliest (2 days after hatching). The PAL, PEL, and germinal centers appeared in turn at 4 days, 6 days and 3 weeks old, respectively. The plasma cells appeared at 2 days of age after hatching. The PAL, PVL, and PEL showed different growth curves, and the numbers of germinal centers and plasma cells also showed different growth curves.
