Appears in exhibition catalog as entry no. 80
We also desire to report that we have examined with great care and interest the invention exhibited by T.E. Mills, known as the photoscope, and we find it to be one of great merit and novelty, being a very ingenious application of certain laws of optics to the production of photography, and that in our opinion does credit to the genius of California suggesting that it receive a Gold Medal.--Awarded a Silver Medal.
