the other refinous, eleflricity 



Th 



opinion 



I am inclined 



.fpoufe, but (hall not here enter into a detail of the theory; but (hall 

 only obferve, that the experiments on vegetation have been principally 

 made with the accumulation of the vitreous elearicity only, and the 

 confequent exclufion of the refinous ; that is, with what is commonly 

 termed pofitive eledricity, and not with what is termed negative 

 elearicity. It is therefore to be wiflied, that fome future experiments 

 may be made with the refinous or negative elearicity in preference 

 to the vitreous or pofitive elearicity, or with both of them alter- 



ternately or comparatively. 



The influence of pofitive or vitreous elearicity in forwarding th 



o;ermination of plants and th 



o 



th feems to be pretty well efla 



bliflied ; though Mr. Ingenhouz did not fucceed in his experiments 



and thence doubts the fuccefs of thofe of others ; and though

Rouland, from his new experiments bel

had previoufly been fupporters of the contrary doft

Mr, D'Ormey not only found various feeds to vegetate fooner, and 

 to grow taller, which were put upon his infulated table, and fuppli- 

 ed with elearicity ; but alfo that filk- worms began to fpin much
