5. In 162 subzygomatic injections of the mandibular division of the trigeminus from the 2 centimeter mark: (a) The average vertical angle was 108 degrees, and the horizontal angle, 91 degrees. (b) In 62.2 per cent, the corresponding angles on the right and the left agreed within 5 degrees. (c) In 32.1 per cent, the angles varied within 10 degrees. (d) In 3.7 per cent, the angles varied more than 10 degrees. (e) In 75.4 per cent, of the cases in which the cor¬ responding angles of injection by
