In our gardens, which Linn/e called Piarat/ Brothels, bastards 

 and enf orced 



have been created throiigh artif icialj crossings in the fertiliza ~ 

 tion. Ihrough accident, of course, something similar could' come

 that in Paris, and, may-be in Brüssel ' one could find, what you are 

 looking for ::Only, somebody at the very place would have to under« 

 take the project and supervise it.. London is also a possibility for
