As to the ///^ of the parts of Plants , efpecially the paflTage 
of the Aliment, he is very fparing, and modeft in giving his 
opinion about it, judging it diflFicult not to miftake herein. 
Mean time, he interfperfes , in the Explication of their ftni- 
fture, his thoughts concerning it, having well confidered the di- 
verficy of VeflTels in Plants , viz, the great number of pervious 
Fibres m the Bark, the abundance of other Fibres in the Lig- 
neous part, fome of which are composed of a Spiral zone, others 
made up of roundifli Bubbles, opening, as 'twere, into one ano-
