The discussion then wavered between apoplexy and concussion, and ended by some good-humoured sparring between Dr. Addison and Mr. Gilbert Burnett, on the capability of the brain containing more blood at one time than another. The President announced from the chair that a special meeting would take place on Friday evening, December 12, at 7 P.M. December 20th, 1828. CÆSAR HAWKINS, ESQ. IN THE CHAIR. After some business had been dispatched, to which we shall allude in another place, Mr. Jewel related the particulars of a case of "supposed extra-uterine fœtation." The case, which is one of much interest, is as follows:-- Mrs. F. a robust, healthy woman, ætatis 27, had been married one year, and aborted once; when, in the month of September 1827, she quitted her husband in London, and accepted a situation in the country. After the expiration of a few weeks she received permission to come to London for a day; and, naturally enough, passed that night, (November 8th), with her husband, returning again to the country next morning. Soon afterwards, the morning-sickness, heart-burn, and other sympathetic affections of pregnancy, appeared; but the catamenia still returned at the regular periods, though scanty and paler in colour than natural. She now quitted her situation, returned to her husband, and engaged a midwife to attend her in her expected confinement. The circumstance of quickening occurred in the latter part of February, and was accompanied by a severe paroxysm of fainting, whilst the abdomen gradually enlarged, and the motions of the child (as was imagined) could not only be easily detected with the hand, but were visible to the eye. On the 9th of August, making a period of 274 days, she was seized with the usual premonitory symptoms of labour; the midwife arrived; found her walking her chamber, and concluded that the process had considerably advanced. Three distinct uterine contractions took place subsequent to the midwife's arrival, the last of which was so severe as to compel the patient to grasp firmly the back of a chair, and induce, after its subsidence, excessive faintness. From this time no further parturient effort was made; no examination per vaginam was instituted; neither was there noticed any sanguineous vaginal discharge. When Mr. Jewel saw her, examination detected nothing unusual in the os uteri, and the symptoms she presents are these. The abdomen is about the size of a woman's in the sixth or seventh month of pregnancy, the enlargement being general. Her general health is much disturbed: she complains of pain in the left hypogastric region, particularly when the abdomen is compressed by the hand or stays--and she also complains of weight in the abdomen, especially on leaning forwards. The woman herself has a strong prepossession that "something is to come away," or that she might be relieved by an operation. The woman believes that she still feels the motions of the child, though feebly.
