Hirst mentions a negress of nineteen who had nine mammae, all told, and as many nipples. The two normal glands were very large. Two accessory glands and nipples below them were small and did not excrete milk. All the other glands and nipples gave milk in large quantities. There were five nipples on the left and four on the right side. The patient's mother had an accessory mamma on the abdomen that secreted milk during the period of lactation. Charpentier has observed in his clinic a woman with two supplementary axillary mammae with nipples. They gave milk as the ordinary mammae.英文原著 · 《Anomalies and Curiosities of Medicine》
