Moreno Studio, Fifth Ave., New York.
"I have been using Merck's pyro in my studio, and am very well pleased with it. It is clean, gives brilliant negatives, and is reliable, one day's work being exactly the same as another's."
A. Moreno.
"I have been using Merck's pyro, and am ready to indorse the high praise which you have found it entitled to: 'that it is superior in point of purity, lightness and solubility' to any like product that I have seen. In fact, 'the new and improved process' seems to reach in its result the point beyond which it is impossible to go—that is, perfection. This was my impression at first sight, and using serves only to confirm it.
In my opinion, pyro stands at the head of all developers of dry plates, and I am much mistaken if Merck's pyro, when known, does not lead all brands of pyro."
