I 125 Hair is continued to the ungual extremity of thephalanges of both manus and pes; the heels in the fully-haired embryo are almost wholly naked. The hair when first present is so pale as to be practicallycolourless; when the embryo is fully haired the hair is of avery pale Fig. manus, 35 mm. stage. Stnsory Papillae and Vibriscae.—Sensory papillae aredeveloped at the 35 mm. stage and vibriscae are present at50 mm. The first papilla to appear is the ulnar-carpal. Facial Vibriscae.—The mysticial set consists of 6 rowsof papillae (in CoUetts description 7), giving rise to 2, 5, 7, 6,6, and 5 backwardly-directed, pale vibriscae, supraorbital papilla is large, and gives origin to 2vibriscae. The genal bears 6 long sensory hairs. Theinterramal is inconspicuous, with 2 pale hairs; and the 126 submental consists of small papillae with rather trivial butearly developed hairs (see fig. 3). Brachial Vibrlscae.—The ulnar-carpal papilla is large,and gives rise to a brush of half a dozen or so pale bristles.
