Sensitive Material

Famous quotes containing the words sensitive and/or material:

“We have lit upon the gentle, sensitive mind
And lost the old nonchalance of the hand;
We are but critics, or but half create,
Timid, entangled, empty and abashed,
Lacking the countenance of our friends.”
—William Butler Yeats (1865–1939)

“[T]he asphaltum contains an exactly requisite amount of sulphides for production of rubber tires. This brown material also contains “ichthyol,” a medicinal preparation used externally, in Webster’s clarifying phrase, “as an alterant and discutient.””
