$not witnessed. I am disposed to think tliat melanosis is less frequent in this country than in Europe. In the Parisian hos- pitals, Bayle met with it in about a twelfth part of his autopsies. CALCAREOUS CONCRETIONS. These substances are frequently observ ed in the lungs and bronchial glands. They are mostly encysted (PI. III. fig. 2.), and give a gritty sensation to the fingers. Their consistence, liovv ever, is much varied, and they appear to be an intennediate link Ixitween tubercles and bony concretions. Analysis shows them to consist of ninety-six parts in the one hundred of saline substances, the remainder being animal matter. M. Andral considers them tubercles that have undergone an earthy trans- formation, an opinion that requires further proof. OSSEOUS CONCRETIONS. Bony masses are frequently secreted by the arteries in the lungs and their appendages: in the fonner they are mostly rounded, and enclosed in a cyst; in other instances they have a rough surface, by which they are firmly attached. In the bronchia, tliey are branched in the direction of the air-tulies. In the glands they are often groiqied. DISEASED BRONCHIAL GLANDS. Ihcse bodies are particularly subject to hypertrojihy: when cut their substance is pulpy, traversed by white lines. They often contain tuliercles, and calcareous and osseous concretions. (PI. XII. fig. 2.) Again, they are occasionally softened, wholly or jiartially, into a yellow ish, cheese-like substance. \ arious minor pathological conditions of the tlioracic vis- cera, w ill be noticed in the course of the follow inf; pages, c$
