The aim of this essay on the structure and function of the spleen is to bring together in somewhat concise form all the available knowledge concerning this organ up to the present moment. However, time and the difficulty of obtaining valuable articles has limited this essay considerably. The first few pages while not giving a very detailed historical background may be considered quite adequate for the purpose intended. The evolutionary development of the spleen is here considered in broad outline. The microscopic anatomy of the spleen and its function in relation to the blood have been considered in greater detail which necessitated, in turn, a consideration of certain pathological conditions in which this spleen is often involved. Special attention has been given to two diseases, splenic anemia and jaundice. The relation of the spleen to bone marrow has been considered in detail while its relation to other organs, such as the thymus for instance has not been so considered, principally because of the contradictory results brought forth by different investigators.

The material for this essay has been drawn in the main from the articles which comprise the bibliography accompanying this work.
