                     DESCRIPTION OF ILLUSTRATIONS.

Plate I.—Macroscopic lesions three-fourths the natural size.

Liver.—Specimen No. 1532 shows a number of the specific pseudotubercles through the trans-
parent capsule. The majority of the nodules are discrete but a few are coalesced.

Specimen No. 562 iii.—Liver capsule shows ' miliary ' pseudotubercles.

Specimen No. 750-B.—A conglomeration of calcareous, pea-sized nodules has produced an
elevation of the hepatic surface.

Specimen No. 1558.—Section through the liver parenchyma shows numerous pearl-white nodules.
Section on the right shows degrees of perihepatitis.

Specimen No. 993 shows hard indurated nodules on the capsule.

Intestine.—Specimen Nos. 562, ii & 1931 (left).—Peritoneal surface of the intestine shows
distinct nodular excrescences.

Specimen Nos. 1931 (right) & 909 show the intestinal mucosa with the typical minute ulcers
characterised by black hæmorrhagic surface.

Lungs.—Specimen Nos. 1481 & 750-A show the lung pleura, the former affected with a
single discrete nodule and the latter with an accumulation of more or less distinct pseudo-
tubercles.

Specimen No. 1562—Lung parenchyma shows discrete and coalesced nodules.
Plate II.—Fig. 1. Low power microphotograph of a portion of diseased liver showing how
the organ is packed with nodules in various stages. One or more circular rings can be
seen in the central pith of each nodule. Empty spaces due to the central degenerated area
having fallen out are seen also.

Fig.2.—Low power microphotograph of a portion of affected intestine. Varying sizes of the
nodular lesions are seen involving all the coats with a preponderance of lesions in the sub-
mucosa and subserosa. The mucosa appears to be more or less intact.
