The largest masses were thisie that could be felt distinctly isolated, with compressible lung sulsituncu round alHiut them, us in Outes 1 and 2, and also in C'ases 11 and 12; such large musses were usually in the jieriphery of the lung, and they had sometimes the unmisUkable wedge-shape of an embolic infarct; it happtmed in three coses that one of the lungs contained only one or two such masses, their )ir(is<mco Injing <letecte<i by fueling the lung all over. Fig. 7, i'late III., is a coloured drawing of one of them (from Case 2). The moss occurred un the i»osterior thick Ixirder of the lung, in the lower lobe close to llie gn>at intcrlolmr fissure.

The upper lol>e of the lung was of a bright rose-red colour, and per- fectly healthy; the lower lobe, in which the mass was situated, diil'ered chiefly in being somewhat more congested, and in having some portion of the base carniiied. The cut surface of the w’edge-shn]>ed mass showed it to be made up of the confluence or conglomeration of a number of round no<lule8, which were them- selves nearly as large as peas (see Drawing). Ilut when a jwrtion of the tissue (from the other half of the wedge, which ha<i l>een preserved in {wtassium bichromate and afterwards in spirit and water, and pure spirit) was examined in microscopic sections, the nodules of the size of peas were found to be not the](https://iiif.wellcomecollection.org/image/b2226758x_0070.jp2/full/800%2C/0/default.jpg)
