"tenacious paste"
Ah yes, those immortal lines from Book II of
The Art of Preserving Health by John Armstrong MD (1709-79)...
Nothing so foreign but th'athletic hind
Can labour into blood. The hungry meal
Alone he fears, or aliments too thin;
By violent powers too easily subdued,
Too soon expelled. His daily labour thaws,
To friendly chyle, the most rebellious mass
That salt can harden, or the smoke of years;
Nor does his gorge the luscious bacon rue,
Nor that which Cestria sends, tenacious paste
Of solid milk.
(Gosh!)
