    presented itself to him, as is my opinion, he yet perfectly com- prehended the possible occurrence of such. To M. Bouillaud's memoir in the Archives de Medecine, for October 1826,1 take the liberty to refer the reader. My principal aim in this hurried notice is to induce patholo- gists to re-examine the subject with more attention, and more in detail than they have hitherto done. The condition of the bronchial arteries, for example, has not yet been ascertained ; nei- ther have we any precise data for determining the effects likely to be produced by a sudden or gradual obliteration of either branch of the pulmonary artery. A distinguished pathologist, (Cruveilhier) has conjectured that the obliteration of the right or left branch of the pulmonary artery would necessarily produce gangrene of the corresponding lung; but this conjecture is at variance with the symptoms and appearances of the above case, and is, moreover, somewhat opposed to the ordinarily re- ceived physiological notions, in respect of nutrition of the pul- monary parenchyma. Physicians also would do well to study more carefully the symptoms indicating these changes in the condition of the lungs. I have shown that a person may completely recover, at least for a while, from an attack of real pulmonary apoplexy ; but as yet auscultation does not enable us to detect the effusion of blood, whether into the textures by extravasation, or when mere- ly productive of a loading of the air-vessels and subdivisions of the pulmonary artery. Ewplanation of the Engraving, Plate V. A view of the section of the lung referred to in the pre- ceding memoir. It exists in that part of Sir Charles Bell's mu- seum which was purchased from him by the College of Sur- geons in Edinburgh. The manuscript Catalogue contains no information further than that it is a specimen of the soft pulpy tubercle of the lungs. I have shown these not to be tu- bercles, but simply extravasated blood, from which attack the patient had recovered, and lived for a considerable time after- wards. a. a. a. Pins employed to fix the preparation, and show the sound part of the lung with the pleura entire. b. Section of the substance of the lung. The texture seems quite healthy. c. c. c. Masses of coagulated blood seen through the pleura. They vary in size. d. One of these masses cut across. It lay immediately be- neath the pleura, which has also been divided by the section. e. A smaller mass divided in a similar manner. PniNTED BY JOHN STAttK, EDINBURGH.
