Report of the examination of 27,927 school children for color-blindness
A Boston medical report from 1880 by physician B. Joy Jeffries, published by Rockwell and Churchill, recording colour-blindness screening of 27,927 schoolchildren. The single picture is a decorative vignette for the city, showing a lamp above a wreath, a Latin motto on a ribbon, and the seal text BOSTONIA CONDITA A.D. 1630, with a distant view of the town within a circle. A designer might take its classical seal layout, ribbon lettering and wreath framing as a model for civic or institutional emblems.
