On this day (February 3) in the year 1841, the following note was written by E. H. Thomas to Southworth and Pennell: - - - - - - - - - - Brattleboro February 3, 1841 Southworth & Pennell Gent. I have completed my Daguerreotype aparatus[?], but as yet have had but indifferent success. My associate Mr. Wilcox & myself have made a good many experiments, but do not get satisfactory likenesses. I was in hopes when I left New York to accomplish the result without the aid of Blue Glass or reflectors, but we do not succeed. The few that we have taken were by the aid of a blue glass poorly blued. One tolerable result was obtained out in the open air with [text missing due to loss of paper] lenses in 4 minutes without the aid of Blue Glass. We think the Lenses are good because we have produced just as good work with them as with the speculum. But we are apprehensive that our trouble lies in preparing the plate but we cannot yet tell where to look for a remedy. E.H.
