Crookes tube
An especially exciting moment came when the Boston morning papers reported the discovery of the Rontgen or X-rays in 1895. The advanced students in physics of those days will always remember the zeal with which Miss Whiting immediately set up an old Crookes tube and the delight when she actually obtained some of the very first photographs taken in this country of coins within a purse and bones within the flesh.In addition to Cannon, Whiting was also assisted or attended in the X-ray experiments by Mabel Augusta Chase and Grace Evangeline Davis.
