FOREIGN DEPARTMENT. EXISTENCE OF A CANAL IN THE OPTIC NERVE OF THE HUMAN FŒTUS.
IN the year 1816, Dr. Wedemeyer, when the eye of an embryo of about
examining
six months, observed that, on slightly pressthe vitreous humour escaped from the centre of the optic nerve. Having subsequently had many opportunities of repeating his researches, he found a canal in ,the middle of the optic nerve; the anterior opening of which was in contact with the vitreous humour ; its posterior termination could not be ascertained, and, as well as the diameter of the canal, seemed to varyaccording to the age of the foetus. Itis very probable that, at the period of cerebral development, when the corpora quadrigemina contain cavities, the abovementioned canal is pervious through the whole course of the optic nerve, and that it subsequently obliterates from the origin of the latter towards the retina. Dr. Wedemeyer never found it of more than half an inch in length from the retina, towards the decussation of
ing the globe,
confined to his bed. On exami. Dr. Folcieri, of Bozzolo, found an aneurism of the popliteal artery, of the size of a pigeon’s egg, and so painful as hardly to admit of the slightest pressure, After the preliminary use of repeated gene. ral and local bloodletting, and of cold lotions, the femoral artery was, in the after. noon of the 5th of June, 1826, tied in the
eventually nation,
extremely
usual manner.
According to Scarpa’s method (which seems to prevail throughout the great. er part of Italy,) a small cylinder of linen, covered with cerate, was placed between the vessel and the ligature ; after the appli. cation of which, the pain and pulsation in
the aneurismatic tumour immediately ceased, On the morning after the operation, the wound was considerably swelled, the fever but, after copious blood. very high, &c. ; letting, these symptoms rapidly disap. peared ; and, twenty-four hours after the operation, the wound being in full suppura. tion, the cylinder and the ligature were withdrawn, and the edges of the wound brought into close contact. The artery seemed perfectly oblite:tated, for the pulsa. tion in the aneurismatic tumour did not return ; the wound from the operation speedily healed ; and, on the 22d of August, the tumour in the ham had completely dis. appeared.—Annal.
