Heschl published in Vienna in 1878 a description of a girl of seventeen, who instead of having a duplication of the superior body, as in "Millie-Christine, the two-headed nightingale," had double parts below the second lumbar vertebra.

Her head and upper body resembled a comely, delicate girl of twelve.
Wells a describes Mrs.B., aged twenty, still alive and healthy.

The duplication in this case begins just above the waist, the spinal column dividing at the third lumbar vertebra, below this point everything being double.

Micturition and defecation occur at different times, but menstruation occurs simultaneously.

She was married at nineteen, and became pregnant a year later on the left side, but abortion was induced at the fourth month on account of persistent nausea and the expectation of impossible delivery.
