20°, THE STRUCTURE OF MAN 
If the supernumerary teat is sufficiently large, it can be used 
for sucking; but it is generally too small for this purpose, and 
is merely an encumbrance, since when the child is being fed 
from the normal breast, milk may dribble from the accessory one. 
Hansemann has recorded the case of a married sempstress, 
forty-five years old (Fig. 13), who had, above and laterally to 
the normal breasts, two accessory ones, which possessed teats, but 
hardly any areole. Above the supernumerary teat of the left 
side there was another one showing distinct orifices. Glandular 
tissue could be discerned below all five teats, and many accessory 
apertures were found in the areole of the normal breasts. In 
the twenty-one years of her married life this woman had given 
birth to twelve children, twins being born twice, and had had 
seven advanced miscarriages; she had thus passed through 
seventeen pregnancies. All the breasts yielded milk, but a 
child could only be fed from the normal ones, since these alone 
were furnished with teats which could be seized by it. 
Hansemann records in his treatise 262 cases in all: 81 males, 
104 females, and 77 in whom the sex is not stated. The author 
refers to the goddesses Isis and Diana, who were represented 
with many breasts as a symbol of fruitfulness; but he rightly 
adds that, judging from data of the present day, the myth can 
have had no foundation in fact. 
I have to thank my pupil Kenkitzi Horiuchi for the record 
of a case of polymasty, published in the Weekly Medical Journal 
of Tokio, of 4th July 1891 (No. 692), which may be added to 
Hansemann’s series. It is that of a Japanese girl, aged nineteen, 
who was examined in the hospital of Fukui. Above the normal 
well-developed teats, at a distance of 4 cm., there was on each 
side (Fig. 14 m”) an accessory teat of the size of a pea, dark in 
colour, and in all respects hke a true nipple. Above, and at 
some distance laterally from the normal breast on each side, 
a second smaller breast (m’”) was found, with a teat. Fig. 14 is 
taken from a photograph of this case. The girl was in all other 
respects normal, and menstruation began at the age of fifteen. 
In conclusion, I append some observations for which I am 
indebted to Otto Ammon, of Karlsruhe, distinguished for his re- 
searches into the anthropology of Baden. The data were obtained 
in connection with the recruiting for military service in the 
year 1890; and the manuscript bears the title, “Some Observa- 
tions on the Occurrence of Supernumerary Teats, and on the 
Direction of the Hair on the Breasts.” Out of 2189 men (of
