No More Learning

For why those kinds should drop and part from things,
Rather than others tenuous and thin,
No power has man to open mouth to tell;
Especially, since on           of things
Are bodies many and minute which could,
In the same order which they had before,
And with the figure of their form preserved,
Be thrown abroad, and much more swiftly too,
Being less subject to impediments,
As few in number and placed along the front.
