TEGUMENTAL ORGANS 25 
ma’) lying in shallow depressions of the axillary folds, and thus 
still more lateral in position than in the case above described 
(Fig. 15). In descending order, below the normal teats, came a 
pair of tolerably distinct though small teats with areole (m’) ; 
and lowest of all two small rudiments (bilaterally symmetrical 
pigment spots, ma”) lying below the ribs. 
This case suggests that the demonstration in the human 
embryo of a mammary line or ridge like that above described in 
the quadruped may be only a matter of time.’ 
supernumerary teats appear; they lie, however, below the normal teats, while in 
the man in your large photograph (Fig. 15) they lie above these. 
‘“The greater development of hair at those parts of the body which correspend 
with the position of supernumerary teats below the normal ones, 7.e. on the con- 
verging lines, has twice been observed by me, and in each case on both sides of 
the body. The stronger hairs do not form tufts, but lie parallel and close 
together, and follow the general course of hair, 7.e. have the same direction as the 
rest ; they are merely longer, thicker, and perhaps also darker. The fact that they 
do not form vortices deterred me from connecting them with rudimentary teats. 
The facts, however, are worth recording.” 
1 Further information on the subject of supernumerary teats and mammary 
gland, can be obtained from the works of Mitchell Bruce (Jowr. Anat. and Phys., 
vol. xiii. p. 425) and Karl von Bardeleben (Verhandi. d. Anatom. Geselisch., Miinchen, 
1891 ; and Wien, 1892). I would, however, warn inquirers against the danger of 
seeing a teat in every wart-like prominence !
