ideas are required, which is not the case when the ideas are reiterated
in the natural way by hearing, or by reading.--On this subject see the
Experiment made before the Clergy and Teachers of Stirling, in July
1833, with "Blind Alick" of that place, who could repeat the whole
Bible;--and the Supplementary Experiment to ascertain the same
principle, made in the House of Correction in Belfast, before the
Teachers and Clergymen of that town, in December 1837.

Note E, p. 83.--Perhaps it may be found, that "Grouping," and
"Classification," are only different manifestations of the same
principle. But even if it were so, it would have been necessary here to
treat of them separately, on account of the very different uses made of
them by Nature. The present, be it observed, is not a metaphysical
treatise, but a humble attempt to be popularly useful.--See Note C.

Note F, p. 105.--This principle may by some be considered as "instinct,"
and others may affirm that it is "reason." All that we require to do
here is to point out the phenomenon,--not to define it. The name is of
little consequence. It is the principle itself, as perceived in its
manifestations, that we have to do with, for the purpose of successfully
imitating it in our dealings with the young.

Note G, p. 132.--There needs scarcely any farther proof of this than the
fact, that barristers, by constant practice, are usually the most fluent
extemporaneous speakers. It is also strongly corroborative of the
statement in the text, that clergymen generally, and especially those
who are most accustomed to the use of extemporaneous prayers and
sermons, find most ease in replying to an opponent on any subject that
is familiar to them.

Note H, p. 160, & 201.--It is a very remarkable fact, to which the
attention of the writer was lately called, that Mrs Wesley, the mother
of the Rev. John Wesley, founder of the Wesleyan Methodists, appears to
have acted upon the principles here developed. In Southey's Life of that
great man, there occurs the following Note:

"Mrs Wesley thus describes her peculiar method (of teaching her children
to read,) in a letter to her son John, (the founder of the Wesleyan
Methodists.)

"None of them were taught to read till five years old, except Kezzy, in
whose case I was overruled; and she was more years in learning than any
of the rest had been months. The way of teaching was this: The day
before a child began to learn, the house was
