"The most sur-prising and honourable operation of surgery ever performed, was, without any contradiction, that executed by M.Richerand, by taking away a part of the ribs and of the pleura. The patient was himself a medical man, and not ignorant of the danger he ran in this operation being had recourse to; but he also knew that his disorder was otherwise incurable. He was attacked with a cancer on the internal surface of the ribs and of the pleura, which continually produced enormous fungo-sities, that had been in vain attempted to be repressed by the actual cautery M. Richerand was obliged to lay the ribs bare, to saw away two, to detach them from the pleura, and to cut away all the cancerous part of that membrane.

"As soon as he had made the opening, the air rushing into the chest, occasioned the first day great suffering, and distressing shortness of breath; the surgeon could touch and see the heart through the pericardium, which was as transparent as glass, and could assure himself of the total insensibility of both. Much serous fluid flowed from the wound, as long as it remained open; but it filled up slowly by means of the adhesion of the lung with the pericardium, and the fleshy granulations that were formed in it. At length the patient got so well, that on the twenty-seventh day after the operation, he could not resist the desire of going to the Medicinal School, to see the fragments of the ribs that had been taken from him; and in three or four days afterwards he returned home, and went about his ordinary business. The success of M. Richerand is the more important, because it will authorize, in other cases, enterprises, which, according to received opinions, would appear impossible; and we shall be less afraid of penetrating into the interior of the chest. M. Richerand even hopes, that by opening the pericardium itself, and using proper injections, we may cure a disease that has hitherto always been fatal, the dropsy of that cavity." - Thomson's Annals.
