Fainting, nevertheless, is a frequent appendage, and is peculiarly apt to lead astray. This, however, can hardly be called an idiopathic disease. M. Portal has drawn his description entirely from post-obit appearances in those who have died of severe atonic typhus, or of plague: and observing, as M. Chicoyneau had before him, occasional proofs of suppuration and gangrene of the heart, he has inferred the previous existence of carditis, and has ascribed the almost instantaneous sinking of the patient to a rapid march of inflammation in this organ, notwithstanding it was not manifestly accompanied with its ordinary indications *.

Hewson, as we have already seen, first suspected, and Mr. Hunter afterwards endeavoured to establish, that this fluid is nothing more than coagulable lymph thrown forth from the vasa vasorum, but changed in its nature in consequence of passing through vessels in a state of inflammatory action. And it was this discovery, and the hint thus founded upon it, that gave rise to the doctrine now so generally admitted, and apparently so well sustained, of a distinct secretion of pus, in many cases

without ulceration. Causes and The causes of carditis are often obscure: where we can

trace them, they are for the most part those of pneumonitis; and the mode of treatment needs not essentially vary. Dr. Frank gives an interesting case of violent carditis brought on by terror in a prisoner condemned capitally. It proved fatal, but on dissection was found not to be confined to the heart.

be known, they have no more claim to be admitted into a system of symptomatic nosology than into a treatise of practice. Dr. Cullen is right in assigning them a place in the former; and he is, therefore, necessarily wrong in banishing them from the latter; and the more so, as the treatment ought, in some degree, to vary from that of enteritis, to which his general observation seems chiefly

to refer. « E. Perito The TRUE PERITONITIS occurs, as we have already obnitis pro
