 as the most certain antidote, to destroy the pernicious effects ac y 

 of this acrid principle. 



The presence of free phosphoric acid in plants is an in- Free pbospho- 

 terestiug fact, but how is it produced there ? Does it puss [^"gets it in- 

 directly from the earth into plants? or does it come from to plants.- 

 phosphorus absorbed by the plant from the soil? Of these 

 two questions the authors have sought the solution; and 

 various arguments, supported by accurate observation, have 

 led them to think, that the phosphorus existing in the ani- 

 mal matters employed to promote vegetation passes in 

 combination with fats and oils into the plants, where it 

 combines with oxigen, and produces the phosphoric acid we 

 meet with.
