The breadth of the superior arch was If line ; length li. 4. The jaws of an embryo nine weeks old were examined under water. Upper Jaw.—No material change had taken place in the configuration of the palate, except that the median lobule {m, Fig. 8), had di- '\i>\~ minished relatively, and in the trans- verse direction, while the lateral « ^. Fig. 8. lobules {ii) had increased relatively, and also in the transverse direction. A longitudinal lobule {y), had also appeared on the surface of the median lobule {m). The cleft (x) in the soft palate was smaller. The posterior part of the dental groove was wider. The papilla (1), had become more prominent, and the lips of the groove had almost met before and behind it. The papilla (2) is larger. A little further on, corresponding with the lateral lobule (ii), on each side, two papillts (3 and 4), with notched lamime in front of them, had appeared. The centrals (3), or those on each side of the median line, were the most distinct. Lower Jaw.—The lips of the dental groove had approached so as to require separation by the needle to exhibit its contents dis- tinctly. The papilla (1 or 2, Fig. 9) had undergone little change, but two very indistinct bulgings (3 and 4) had appeared on each side of the labial frenum, the centrals (3) being the largest. The breadth of the superior arch was 1% line ; the length 1^ Please note that these images are extracted from scanned page images that may have been digitally enhanced for readability - coloration and appearance of these illustrations may not perfectly resemble the original Goodsir, John, 1814-1867; Lonsdale, Henry, 1816-1876; Turner, William, Sir, 1832-1916.
