McElmail describes a soldier of twenty-nine, who two or three months before examination felt a pricking and slight burning pain near the internal aperture of the internal inguinal canal, succeeded by a swelling until the tumor passed into the scrotum.

It was found in the upper part of the scrotum above the original testicle, but not in contact, and was about half the size of the normal testicle; its cord and epididymis could be distinctly felt and caused the same sensation as pressure on the other testicle did.
Marshall mentions a boy of sixteen in whom the right half of the scrotum was empty, although the left was of normal size and contained a testicle.

On close examination another testicle was found in the perineum; the boy said that while running he fell down, four years before, and on getting up suffered great pain in the groin, and this pain recurred after exertion.

This testicle was removed successfully to the scrotum.

Horsley collected 20 instances of operators who made a similar attempt, Annandale being the first one; his success was likely due to antisepsis, as previously the testicles had always sloughed.
There is a record of a dog remarkable for its salacity who had two testicles in the scrotum and one in the abdomen; some of the older authors often indulged in playful humor on this subject.
Brown describes a child with a swelling in the perineum both painful and elastic to the touch.
