Excerpt from The Origin and Development of the Lymphatic System, Vol. 5 1. Morphology Of The Vascular System, The Angioblast. Until the past few years our knowledge of the morphology of the lymphatic system was in a very unsatisfactory state. Our conceptions of such main questions as the origin of the first lymphatics, the time of their appearance, the relations of the lymph hearts and sacs of the amphibia to the lymph glands and ducts of higher forms, the relation of the lymphatics to serous cavities and to the various forms of tissue spaces, and the development of the lymphatic vessels within an organ have been so vaguely understood that the opinions of no two investigators approached agreement. A clear conception of any system must be based on an understanding of its fundamental morphology, as, for example, the morphology of the arterial system was placed upon a satisfactory basis by the discovery and comparison of the aortic arches in different animals. An example more closely in touch with our knowledge of the lymphatic system is the study of the fundamental morphology of the blood vascular system. Our knowledge of this is in the process of being built up, but a foundation has been laid for the clear understanding of the vascular system in a series of discoveries. The first and most fundamental of these is that the blood vessels arise as blood islands in the extraembryonal membranes. The earlier embryologists on the other hand believed that the first vessels were spaces without walls, which the pressure of the circulating blood hollowed out.
