    <J. 1According to my Explication, thofe Roots which are produced by pruning, are the little Roots that give Nourilhment to the Eyes (§. 10. c. 6.) On the contrary Mr. Jgricola has obferved that a Sap came out of the Inciiion ; and that after it was fettled the Roots grew out of it. It .feems by this, that Experience contradi&s my Notions which are only founded upon Reafoning. §. 16. I find indeed that Mr, Agricola fays,p. i<5o, that fuch a Sap, by which Nature forms the Roots, is to be met with in general in all Trees.

For I know very well from other Principles, that nothing that is organick can be generated by an i#- orgamck Matter. 17.
