Let us proceed to the higher parts of the creature. 

 Observe the vegetable kingdom. And here also 

 whatever displays the wisdom of the Creator, dis- 

 covers the ignorance of his creature. Who can 

 clearly determine even the fundamental question, 

 concerning the general nature of vegetables. Does 

 the sap perform a regular circulation through their 

 vessels, or not? How plausible arguments have 

 been brought, both on the one side and the other ? 

 Who knows the several species of vegetables, from 

 the cedar of Lebanon to the hyssop on the wall? 

 Or rather, (if we would descend from the highest to 

 the lowest,) to the innumerable grove of plants, 

 which appear in the form of mouldiness; or those 

 more innumerable (if the expression may be al- 

 lowed) \\hich do not appear to the naked eye at all? 

 Who is able to discover the proper specific difference 

 between any one kind of plant and another ? Or 

 the peculiar internal conformation and disposition, 

 or their component particles? Yea, what man upon 

 earth thoroughly understands the nature and proper- 

 ties of any one plant under heaven ?
