LV. An Account of some Experiments made in the Garden of the 

 Horticultural Society, with a view to ascertaining the relative

 far beyond any thing of which either the Farmer or Gardener had 

 a previous conception. 



As a great deal of interest has been excited by these statements, 

 I have thought it might be desirable, in laying before the Society 

 the result of some fresh experiments which have been tried in the

 which might be deduced from theory : and perhaps a more beautiful
