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 areolse (m") ; 

 and lowest of all two small rudiments (bilaterally symmetrical 

 pigment spots, ma") lying below tJM 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. 1 



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 correspond 

 with the position of supernumerary teats below the normal ones, i.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, i.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 (Jour. Anat. and Phys., 

 vol. xiii. p. 425) and Karl von Bardeleben (Verhandl. d. Anatom. Gesellsch., Miinchen, 

 1891 ; and Wien, 1892). I would, however, warn inquirers against the danger of 

 seeing a teat in every wart-like prominence !
