Attend the lean extreme. For physic knows 220
How to disburden the too tumid veins,
Even how to ripen the half-labour’d blood;
But to unlock the elemental tubes,
Collaps’d and shrunk with long inanity,
And with balsamic nutriment repair 225
The dried and worn-out habit, were to bid
Old age grow green, and wear a second spring;
Or the tall ash, long ravish’d from the soil,
Thro’ wither’d veins imbibe the vernal dew.
