ABSTRACT ALL who take a scientific interest in photography and in the investigations of its problems owe a considerable debt of gratitude to the workers in the Research Laboratory of the

Eastman Kodak Company for the preparation and issue of these monographs. The first, on “The Silver Bromide Grain of Photographic Emulsions,” was issued about two years ago and was duly

noticed in these pages. We have before us the next three, and we learn that two more will soon appear, namely, “The Physics of the Developed Photographic Image,” by Dr. Ross, and “Gelatin in

Photography, Volume II,” by Dr. Sheppard. Further, it is hoped eventually to cover the entire field of scientific photography. The editors thus hope “to make available to the general

public” material by numerous authors which is distributed throughout a wide range of journals, as well as the results of a considerable amount of unpublished work carried out in the

Company's Laboratories. The expression “general public “here needs qualification, for the treatises are in no sense popular, nor does there appear to be any attempt to bring the

scientific and mathematical expressions within the popular grasp. Experts will probably value them the more on this account. Each volume is well illustrated, has a good contents table and

full indexes, besides an extensive bibliography and all desirable references to the original sources of information. (1) The Theory of Development. By A. H. Nietz. Pp. 190. (2) Gelatin in
