SYNTHETIC BIOLOGY 121 



Such is the history of morphogenesis as described in 190°. 

 by the authority most qualified for the task, Professor Quinke 

 of Heidelberg. 



In 1904, Professor Moritz Benedikt of Vienna treated the 

 whole question in his hook, Crystallization and Morphogenesis, 

 of which a French translation appeared in the Maloine Library. 

 This hook is full of original and suggestive ideas ; it describes 

 the work of Halting, and more especially that of Van Schroen, 

 who considers that crystals like living beings begin as a cell 

 and grow by a process of intussusception. Professor Benedikt 

 has made a complete resume of the question in an article, " The 

 Origins of the Forms of Life," which appeared in the Revue 

 Scientiflque in 1905. 



In 1904, Professor Dubois of Lyons presented a report to 

 the Society of Biology on his interesting experiments on 

 mineral cytogenesis. The same year he gave a discourse at the 

 university of Lyons on "The Creation of Living Beings," 

 which has been published by A. Storek of Lyons. 



One of the most active of the modern niorphogenists is 

 Professor Herrera of Mexico, whose work is illustrated in the 

 Atlas de Plasmogenie by Dr. Jules Felix of Brussels, one of the 

 most enthusiastic disciples of the new science. There is a 

 resume of Herrera's work in the Memoirs of the S<><i<1t 

 Alzate, Mexico. 



A bibliography of the works which have appeared on this 

 subject may be found in the book of Professor Rhumbler of 

 Gottingen, Aus dem Luckengebiete zwischen Organischer und 

 Anorganischer Materie, 1906. 



In 1907, Dr. Luiz Razetti of Carracas published a magnifi- 

 cent study of the subject under the title Que es la vidu. 



In 1907, Dr. .Martin Kuckuck of St. Petersburg repeated 

 and extended the experiments of 1{. Dubois, and published his 

 results under the title Archigonia, Generatio Spontanea, 

 Leipzig, Ambrosius Barth. 



Butler Burke of Cambridge has also made a series of 

 experiments with radium and barium salts analogous to those 

 of Dubois. 



In 1909, Albert and Alexandre Mary of Beauvais published
