The preparations* have been obtained by the exhibitor by an ammonia- 

 soda process carried out .and developed by himself. This method has been 

 introduced in the exhibitor's factory at Grevenberg, near Aix-la-Chapelle ; at 

 the Nuremberg Soda Manufactory, near Nuremberg ; at the Soda Manufactory 

 of the Rothenfeld Saline and Salt Bath Company at Rothenfelde, near 

 Osnabriick, and at the Aalborger chemiske Fabrikker og Gjodningsfabrik at 

 Aalborg in Denmark. MoritZ Honigmann, Aachen,
