As nearer to him plac’d or nearer tending,
Each in their several active spheres assign’d,
Till body up to spirit work, in bounds
Proportioned to each kind. So from the root
Springs lighter the green stalk, from thence the leaves
More aery, last the bright consummate flower
Spirits odorous breathes: flow’rs and their fruit,
Man’s nourishment, by gradual scale sublim’d,
To vital spirits aspire, to animal,
To intellectual; give both life and sense,
