I should mention also among the works of synthetic biology the publications of Professor Otto Lehmann of Karlsruhe, and in particular Flüssige Krystalle und die Theorien des Lebens, Leipzig, Ambrosius Barth.
Professor Ulenhuth of Berlin has published his study on the osmotic growth of iron in alkaline hypochlorites under the title Untersuchungen ueber Antiformin, Berlin, Julius Springer.
Professor Gariel has made a series of researches on osmotic growth which are published in Abraham's Recueil d'expériences de physique.
A. Lecha Marzo of Valladolid published his researches on the growth of aniline colours in the Gaceta Medica Catalana, 1909, under the title Otra nueva flora artificiale.
Dr. Maurice d'Halluin of Lille has also published a volume on osmotic growths under the title, Stéphane Leduc a-t-il créé la vie?
The subjects of the numerous memoirs that I have myself published during the last ten years upon the question are treated anew in the pages of this volume, and a résumé of my researches on osmotic growth has already appeared in the Documents du Progrès, Sept. 1909.
We have thus shown that synthetic morphogenesis has already attracted the attention of a certain number of ardent investigators. Morphogeny has now its methods and its results, and physiogeny is also developing side by side with it, since function is but the result of form. The field of research is opened, and workers alone are needed in order to reap an abundant harvest.
