The trunk from the left lobe of the thyroide gland shews itself. The whole figure is not yet so complete as I hope to make it; mean time Ihere is nothing put down from imagination. PLATE II. Fig. 1. Represents an outside view of the deep-seated lacteals in the beginning of the ilium, which is here slit open, and spread out. The prepa- ration was taken from a woman who died in labour about five o'clock in the morning. The chyle had coagulated more firmly in the vessels than I had ever seen it before in the human subject. The peritoneal, and part of the muscular coats, are removed, to shew the vessels more dis- tinctly. a, a, &c. Represent six trunks of each side, accompanying the principal trunks of the arteries. They are exactly double the number of the last. Fig. 2. Represents a portion of the inside of the same intestine, in which several villi, or packets of projecting extremities of vessels, enveloped in productions of the inner coat of the intestine, are seen turgid with chyle, and white as snow. ~ Fig. 3. Some of these villi, as they appeared when viewed through the microscope: the orifices of the lactcals, and their radiated extremities, are seen distinctly. The lowermost villus was so turgid with chyle that I could see no orifices. Fig. 4. The radiated extremities of an absorbent vessel entering the gland, as seen by the naked eye. Fig. 5. The radiated extremities of an absorbent vessel emerging from its gland, as seen by the naked eye. Fig. 6. A portion of the skin of the arm, after the cuticle, rete mucosum, and some other separable membranes, were loosened by maceration, and removed by the slightest touch of the handle of the knife; where, though I could not discover the orifices of the absorbents, yet the pores them: selves |
