If too large a quantity of milk be transfused, death occurs.When unboiled milk is injected, numerous bacteria are developed in the blood(Schiifer). The Blood-Glands. 103. The Spleen. Structure.—The spleen is covered by the peritoneum, except at thehilus. Under this SEROUS covering there is a tough thick elasticfibrous CAPSULE, which closely invests the organ and gives a coveringto the vessels which enter or leave it at the hilus, so that fibrous tissueis carried into the organ along the course of the vessels. (The capsulecannot be separated without tearing the splenic pulp.) NumerousTRABECUL/E pass into the spleen from the deep surface of the capsule.These trabeculas branch and anastomose so as to produce a net-workor sustentacular tissue, which is continuous with the connective tissue,prolonged inwards and surrounding the blood-vessels (Fig. 88). Thus,the connective tissue in the spleen, as in other viscera, is continuous

(This net-work iseasily demonstrated by washing out the pulp lying in its meshes bymeans of a stream of water, when a beautiful soft semi-elastic net-workof rounded and flattened threads is obtained.) The Capsule is composed of interlacing bundles of connective tissue 204 BLOOD-VESSELS OF THE SPLEEN. mixed with numerous fine fibres of elastic tissue and some non-stripedmuscular fibres. Reticulum.—Within the meshes of the trabecular framework there isdispersed a very delicate net-work (reticuluni) of adenoid tissue (Billroth),which, with the other coloured elements that fill up the meshes, con-stitute the splenic pulp (Fig. 89). The reticuluni is continuous with thefibres of the trabeculse. (I
