the Trial of the Rev. George B. Vosburgh at Jersey City, May 22, 1878
The chemical apparatuses represent three separate tests to detect antimony. At the bottom of the page, Doremus is shown on the witness stand holding what appears to be a chart of spectrograms. Inset portraits, from left to right: Rev. George B. Vosburgh; Mrs. Jennie Sickles (Mrs. Vosburgh's sister-in-law); Mrs. Harriet Vosburgh; Mrs. Elvira Manton (Mrs. Vosburgh's sister); James Sickles (Mrs. Vosburgh's brother and the Reverend's principal accuser).
