Summary
It is shown by thermodynamical considerations, that in general regardless to the particular nature of a cell, there must be two kinds of forces between cells: a force of repulsion, due to metabolism, and a force of attraction, due to irritability.
It is shown, that the various geometrical forms, which cellular aggregates may assume under the influence of those forces, correspond in general features to various forms, found in nature.
In conclusion I wish to express my profound indebtedness to ProfessorDavenport Hooker, for frequent discussions of the subject and a great amount of valuable information.
