"Some Experiments in Taking Transparencies," by S. Homer Dosh

S. Homer Dosh writes his thesis, titled "Some Experiments in Taking Transparencies," about developing photographs while a student at Dickinson College. While using a piece of ground glass behind the negative film is the most satisfactory method, Dosh admits that the method is "inconvenient, and very often cannot be recorted to at all." Dosh includes several photographs as examples in his thesis.
