 countless inventions, impossible to co-ordinate. 

 They remind one of the model room of the Patent 

 Office. Multitudes of miniature working models 

 of machines are assembled: marvels of ingenuity 

 and fertility of invention. But our floral mechan- 

 isms have this advantage over the patented proto- 

 types that they, at least, help to keep the plants 

 alive, and to aid them in their struggle for exist- 

 ence, which cannot be said in favour of all products 

 of human invention, for we know that many an 

 inventor has starved.
