Clinical lectures on the principles and practice of medicine . ut how, in a young man of perfecthealth, structural disorganization slowly, but surely, proceeds after suchan occurrence, and it strongly inculcates the necessity of early carefulexamination and of operative interference.

As an example we may cite awell-marked ca3e given by Mr. Gr. W. Callender, in the ninth volumeof the Pathological Societys Transactions. One of the tertiary divisionsof the pulmonary artery was oc- cupied by a clot of decolorizedfibrin in the form of a hollowglobule. Its diameter was abouttwo lines greater than that ofthe artery below, so that at thispoint the vessel seemed to haveundergone some slight dilata-tion. Just beyond the place atwhich this clot had obstructedthe canal, the artery blood had penetrated one ofits divisions by means of a shortand narrow channel, formed.

The other division atthe pomt where it again bifurcated, had one of it. divisions obstructedby another clot, which, unlike the others, was solid throughout. Theportion of pulmonary tissue with which this artery communicated, wasin a state of gangrene, as also was its pleural covering. In this casevarious masses of coagulated fibrin were adherent to the tricuspid valve, Fig. 456.
