Withou his spontaneous assistance, as the fermenta fve 
agent, the processes of baking and brewing could not be 
successfully carried on. In the nutrition and growth of 
plants he acts a very important part, and, as the late Sir 
Chailes Siemens has experimentally proved, can be used 
artificially to expedite and improve their fruit-producing 
powers to an extraordinary extent. He can, by a little 
skilful management, be made to work sewing and other
