Ovarian tumours sometimes attain large dimensions in children, and Keen reported a case in which he removed an ovarian tumour from a girl which weighed 44 kilogrammes: the girl weighed 27 kilogrammes after the operation. An ovarian cyst with a twisted pedicle has been found in a fœtus at birth (Otto von Franque). The subjoined table shows cases in which ovarian tumours have been removed from infants under three years of age. It is often stated that Professor Chiene performed ovariotomy on an infant of three months. This is an error; it was an ovary occupying the sac of an inguinal hernia.

Since that date Howard A. Kelly and Mary Sherwood made a collective investigation, and succeeded in obtaining notes of one hundred cases of ovariotomy performed on women over seventy years of age: the death-rate amounted to 12%. The subjoined table concerns itself with ovariotomy performed on women after the age of eighty years, and the results are remarkable, notwithstanding the circumstance that these women of eighty years and upwards must have been blessed with a stronger constitution than their contemporaries.
