Sixthly,--The liver was small in size, excessively dense, and very heavy. Externally, it had a dark olive hue, and on section presented a most curious appearance. The section was of an almost uniform yellowish-green colour, and studded over with excavations (Plate I., _b_), from which thick bile streamed in all directions. The apparent excavations were nothing more or less than immensely distended ducts. On looking into the ducts, it was observed that they presented the appearance of possessing valves. On microscopical examination, the hepatic cells were found smaller than normal, as if partially atrophied. The nuclei were unusually well marked, in consequence of the fat granules being almost entirely absent. (Fig. 8, _b_.) In the field of the microscope were a number of caudate or spindle-shaped cells (Fig. 8, _c_.), from the epithelial lining of the ducts. In the hepatic tissue were found some beautiful {86} stellate crystals, as well as a number of separate needles of tyrosine. A few small crystals of cystine were also found. (Fig. 8, _a_.) [Illustration: FIG. 8.] Seventhly,--The kidneys were enlarged, pale, and fatty-looking; and all over the surface of the section, as well as immediately under the capsules, which were very loosely attached, were small abscesses. The surface was also studded with numerous minute dark bile-pigment points, and it is possible that the abscesses were the result of the blocking up of the capillary vessels by the pigment deposit, as previously alluded to, page 57. Eighthly,--The head of the pancreas was considerably enlarged, and on cutting into it, a quantity of pus oozed out from an abscess in its interior. The abscess was found to communicate with a large ulcerated spot in the duodenum. (Plate I., _f_.) On microscopical examination, the {87} tumour of the pancreas was found to consist of an hypertrophy of the normal gland tissue, being, in fact, a chronic inflammatory tumour of the gland substance.
