At first, however, they are not easily separated fromit (demonstration of the tuberculous nature of such small areas bymeans of au Identification of giant cells) (see page 344). In olderand larger masses which are located in sinuous cavities with smooth Fig. >c Tuberculosis of the dorsal vertebrae in a hog. a, caseous focus; b, deposition of limein the caseous focus; c, bony bands and islands on the border of the caseousfocus; d, sectiou of a vertebra after renioval of the tuberculous produets. cells and which are not easily separated from these, the grayish-yellow color is more conspicuous. Furthermore, we observe in thelarger masses a partial calcification which, however, is neverespecially far advanced, The larger masses in the bones, therefore,possess the character which has previously been designated asfuugous. Tuberculous granulations may attain such a volume thatfinally only a seam-like residue of the normal bone tissue remains.
