 fire-heat, at any period of the flowering

 is not the cafe : as, in mild weather, and 

 in the flowering feafon, the temperature of 

 thejioufe is fuch, as fometimes to require 

 very flow fires 3 and, of courfe, the flue is 

 perhaps not heated enough, to raife fteam 

 in any great quantity. 



It may juftly be faid, that, in this cafe,
