 peared, and nothing remained but the blood-vessels and a very dense fibro-cellular tissue. The whole of this last, however, was removed with very great care and skill, and the preparation now consists of the bones of the extremity and of the vessels only. The vessels are placed in their proper relation to each other and to the bones, which last are surrounded by the veins, as in a piece of basket-work ; and the large and free communication between the arteries and veins is well shown upon the back of the hand and near the first metacarpal bone. The arteries and veins, gener- ally, are only moderately enlarged ; but, where they com- municate, they are considerably so, though only for a short distance.

Dr. Bigelow imported Breschet's Memoir on Aneurisms (Paris, 1834), with reference to this case, and found that it would correspond to his " Varix arterielle ; " the com- munication with the vein being a complication. 1858.

1814-5. Daguerreotypes of a case of varicose arterial tumor.

The patient was a female, thirty-five years of age. (Hos^ pital, 59, 211.) The tumor was of the size of a large hen's egg, directly over the right eye, projecting upon the fore- head, and dipping beneath the orbit ; surface convoluted, of a brilliant red, pulsating heavily, and filling to its ut- most capacity in about three seconds after the blood had been pressed out of it as from a sponge. It was painless, of about twenty years' duration, gradually increasing, and originally near the hair, from which situation it seemed to have gravitated to its present position. Numerous dilated arteries radiated from its circumference. At the operation, the larger trunks were secured by ligature, but the tumor continued to fill with blood until nearly the whole periphery had been included in successive ligatures. "With a view to its radical extirpation, it was then rapidly excised within the ligatures, when the exposed surface bled obstinately, and even after the use of the actual cautery. The wound healed rapidly ; and the patient was discharged six weeks
