+P+.—Because, in these words, there is something said or asserted of leaves.
+T+.—When I say, Falling leaves rustle, does falling tell what is thought of leaves?
+P+.—No.
+T+.—What does falling do?
+P+.—It tells the kind of leaves you are thinking and speaking of.
+T+.—What word does tell what is thought of leaves?
+P+.—Rustle.
+T+.—You see then that in the thought there are two parts; something of which we think, and that which we think about it.
