Meteorological Observations. 295 



pose repeating my own garden experiments with more care than I 

 had thought necessary this year, having hitherto felt sufficiently 

 convinced that Decaisne's statement was correct.

 of Odontites rubra, attached to the fibres of wheat, and you will see 

 what a parasitic aspect they have assumed, whatever their real func- 

 tions may be. I am very desirous of procuring seeds of Melampyrum 

 arvense for experiment, and if any of your correspondents could pro- 

 cure me a few, I shall feel much obliged to them. Hitcham, Sept. 14.
