Abstract

In this paper, points which the writer found to hold in the peripheral sinus of red lymphonodi in goats are somewhat as follows : 1. The peripheral sinuses of the red lymphonodi and the ordinary lymphonodi differ markedly from one another in their minute structures, yet these differences mainly resulted from the variable prominence of certain structural features present in all. 2. The writer classified the red lymphonodi into five types by state of appearance of perirheral sinus, applying the silver nitrate impregnation method. 3. In most portions of the peripheral sinus as in the present types I and II, the cavelet structures were detected. In type I these spongy chambers were found within the capsula itself, while in type II the chambers were beneath the capsula. Moreover, some intermediate features were detected between above mentioned types and the ordinary lymph sinus. These intermediate types were named III and IV. Some red lymphonodi having a peripheral sinus like the ordinary lymph sinus were decided to be type V. 4. As regards the breadth and the quantity of erythrocytes in the peripheral sinus, the writer found the fact that in the case of disappearance of the cavelet structure, the peripheral sinuses become increasingly narrow, and the quantity of erythrocytes gradually decreases. 5. The writer considered that in the earliest stage of the development of the red lymphonodus the cavelet structures appeared in the capsula itself, and when this stage was over these structures were combined so that the peripheral sinus had the same features as ordinary lymph sinus.
