From Leonard Rudd   12 April 1874

Sir

I venture to bring to your notice a fact which came under my observation and which may be of some interest to you.— On Good friday last a man came to me in the Surgery complaining of kicks in the ribs & groin. I stripped him and found that he had besides the two normal nipples upon the chest, two others placed below them; one, that on the left, was as nearly as I could judge, 4$\frac{1}{2}$ in: below and in the direct mammary line: that on the right was $\frac{1}{2}$ in: lower and $\frac{1}{2}$ in: outside the mammary line. Both the supernumerary nipples with their areolæ were smaller than the two normal ones, the left was better developed than the right. But the man stated to me, they changed their size at each month, and had done so “as long as he remembered certainly for 20 years”.¹ At the same intervals he had a feeling of a lump in his throat—the “globus Hystericus” as I understand it.

He was a well formed man about 48— 5^.10 high— had enjoyed good health— had been a soldier, & served his time— had been in India.

I am | Sir— | yours faithfully | Leonard Rudd | Surgeons Dresser to M^r. Bryant.²
