rned here with the Impression and its Revival.

There are (_five_) kinds of memories rising from the natural aptitudes
of different individuals--(1) First Impressions are apt to be feeble and
the power to revive them weak--a poor memory. (2) First Impressions are
usually weak but the power to revive them is strong--still a poor
memory. (3) First Impressions are usually vivid but the power to revive
them is weak--a poor memory. (4) First Impressions on all subjects are
strong and the power to revive them is strong--a first-class memory. (5)
First Impressions in some particulars are very strong and the reviving
power in regard to them is very strong--a good memory for these
particulars, or a memory good for mathematics, or music, or faces, or
reciting, or languages, &c., but usually weak in most other respects.

THREE LAWS OF MEMORY OR OF THINKING.

_The first and principal thing the pupil requires to do in this lesson
after learning the definition of the following Three Laws--is to be able
to clearly understand the examples under each Law, and whether they
verify or illustrate that Law._
