numerous spots of mould or mildew. The majority of these 

 spots were round, and somewhat elevated, especially at the 

 centre. They were of different sizes ; from a line to the tenth 

 of a line. The largest had an irregular circumference, which 

 was evidently the result of the confluence of several neigh- 

 bouring spots, whose projecting centres shewed the different 

 spots whence they had originally sprung. Although most nu- 

 merous on the parietes of the chest, the mouldy spots were 

 found throughout the whole extent of the air-cells, including 

 the loins ; also upon the intestines, the bones of the pelvis, and 

 in the air-vessels of the anterior extremities. None were to 

 be found upon the pericardium, nor within the large blood- 

 vessels ; nor were there any in the trachea, nor in the larynx, 

 but they abounded in those bronchial tubes which traversed 

 the lungs to communicate with the air-cells. The^air-tubes of 

 the left side were all clothed with old mouldiness, of mature 

 growth, for the sporules were completely developed, of a deep 

 dirty green colour, and united in capitula, which were support- 

 ed on straight filaments. It appeared that none of these ra- 

 mifications of the bronchiae, which terminated in the substance 

 of the lungs, were covered with the mould ; and the lungs, 

 though somewhat gorged with blood, were quite permeable 

 to air. floated when plunged into water, and contained neither 

 tubercles nor ulcerations. From the advanced state of the 

 growth of the mould in the left bronchiae, it was inferred that 

 the disease commenced in these parts, and thence gradually 

 extended to the right bronchiae, in which the spots appeared 

 quite recent, and almost colourless. 



The membrane which corresponded to the serous one of the 

 thorax and abdomen, and of their contained organs, and which 

 is also a prolongation of the mucous membrane of the trachea 

 and bronchiae, was found, under the large and old spots of 

 mould, to be thick, red, and conspicuously injected with blood. 

 A large piece of this sero-mucous membrane was detached by 

 dissection, and placed, with its face external, upon a round 

 body, that the mould might more easily be examined, and it 

 was then found that the spots could very readily be entirely 

 separated from it. Interposed, however, between the sero- 

 mucous membrane and the minute Cryptogamia, there was a
