[link]1887 Image Credit: Thomas A. Fine Construction of the dome to contain the 28-inch reflector donated by Mrs. Draper for the Draper Memorial project. Eleven photos processed into an animated gif. Some alternate copies of these images have penciled in dates, and based on this, the construction began before July 12, 1887 (when the platform was completed), and completed after September 1 of the same year (when the building skirt was added but the dome skirt was not in place). A copy of the sixth image in the sequence has a date written on it, which dates the middle of the construction to July 27, 1887.olvwork432353(missing) The position of the building makes it clear that this is the dome for the 28-inch reflector, which was the second of the three large additional domes that were built.
