"Photographic Emulsions" by E.J. Wall (1929)

I've worked up a PDF of the vintage book "Photographic emulsions; their preparation and coating on glass, celluloid and paper, experimentally and on the large scale" by E. J. (Edward John) Wall, Boston, American Photographic Pub. Co., 1929.

This book is definitely out of date in many ways - all of the formulas are for "active" gelatin, as that was all that was availble at that time. Which also means that the process of sulfur sensitization had not been invented, which will be needed if a modern gelatin is used instead of a vintage-style, active gelatin. Also, Wall has left out some specific info that will probably make it hard to reproduce his formulas as well.

But, despite it's faults, it's an interesting read, from both technological and grammatical view points!
