In view of the increasing number of operations on the tonsil because of the focusing of medical eyes on it as a primary source of metastatic infections, because of the discovery of more cases in the systematic inspection of schoolchildren, and because of the popularity of complete ablation of the tonsil in preference to partial tonsillectomy, a timely note of warning should be sounded of the liability of serious if not fatal hemorrhage from wounding a loop of an anomalous internal carotid artery. The following specimen, found in the Anatomical Laboratory of the University of Pennsylvania, serves as a striking example of this:

—Specimen consists of left side of skull containing the internal carotid artery in situ and dissected free from surrounding tissues. The artery is of uniform caliber throughout its length, and its walls neither thickened nor calcareous. Beginning
