liver and spleen there is a deposit of anthracotic pigment. 
Cast V.—Acute miliary tuberculosis of the lungs in a case of 
stone-cutter by trade. 
Anthracotic pigmentation of both lungs is only moderate, 
but highly marbled with fine tubercles, to which I have 
given the name of “miliary stone-cutters’ tubercle.’”’—GaERTNER; 
slight, slaty induration, with marginal emphysema; no formation of 
cavities or infarctions. The bronchial and tracheal lymphatic glands 
at the base are enlarged, indurated and slaty; some are adherent to 
the bronchi and the surrounding vessels, the walls of which are more 
or less infiltrated with anthracotic pigment. On opening the bronchi 
and vessels, there was found an opening in the left principal 
bronchus. In the liver and spleen is found a deposit of black 
pigment. 
Cast VI.—Eaquisite slaty induration of the lungs. 
The anthracotic pigmentation of the lungs is decidedly very 
great; the upper lobes of the right lung are almost devoid of air, 
and are considerably indurated with slaty cicatrices, in consequence 
of which several bronchial cavities (bronchiectasis) were found 
therein. At the same time, the quantity of blood in these lobes is 
diminished. On the contrary, the right lower lobe and the entire 
left lung have an increased capacity for blood, but are affected by 
vesicular emphysema. The bronchial lymphatic glands at the base 
are enlarged, indurated and slaty; a few of them are, to a great 
extent, adherent to the neighboring bronchil and pulmonary arte- 
ries, the walls of which are somewhat infiltrated with coal pigment. 
A larger, black, lymphatic gland is somewhat softer than the others 
and adherent to the right principal bronchus, the wall of which at the 
place of juncture is greatly infiltrated with anthracotic pigment. 
An incision into the bronchus shows a steel-like, slaty cicatrix, in 
the center of which was disclosed an opening. In the liver and 
spleen, there is a deposit of black pigment. 
Case VII.—Cdema of the Lungs. 
Anthracotic pigmentation of bothlungs is strong, but no special 
indurations ; blood capacity is increased, the capacity for air dimin- 
ished. The bronchial and tracheal lymphatic glands at the base are 
very large and black but not especially indurated; a few of them 
have grown fast to the surrounding vessels, the walls of which are 
streaked with coal pigment. A larger black gland lies close to the 
right principal bronchus-and is adherent to it. An incision disclosed 
a breach in the principal bronchus. The spleen is very large and
