blush of young girls on coming into an assembly room, where they expect
their dress, and steps, and manner to be examined, as in dancing a minuet,
may have another origin; and may be considered as a hot fit of returning
confidence, after a previous cold fit of fear.

7. _Tarditas paralytica._ By a stroke of the palsy or apoplexy it
frequently happens, that those ideas, which were associated in trains,
whose first link was a voluntary idea, have their connection dissevered;
and the patient is under the necessity by repeated efforts slowly to renew
their associations. In this situation those words, which have the fewest
other words associated with them, as the proper names of persons or places,
are the most difficult to recollect. And in those efforts of recollection
the word opposite to the word required is often produced, as hot for cold,
winter for summer, which is owing to our associating our ideas of things by
their opposites as well as by their similitudes, and in some instances
perhaps more frequently, or more forcibly. Other paralytic patients are
liable to give wrong names to external objects, as using the word pigs for
sheep, or cows for horses; in this case the association between the idea of
the animal and the name of it is dissevered; but the idea of the class or
genus of the thing remains; and he takes a name from the first of the
species, which presents itself, and sometimes can correct himself, till he
finds the true one.

8. _Tarditas senilis._ Slowness of age. The difficulty of associating ideas
increases with our age; as may be observed from old people forgetting the
business of the last hour, unless they impress it strongly, or by frequent
repetition, though they can well recollect the transactions of their youth.
I saw an elderly man, who could reason with great clearness and precision
and in accurate language on subjects, which he had been accustomed to think
upon; and yet did not know, that he had rang the bell by his fire-side in
one minute afterwards; nor could then recollect the object he had wanted,
when his servant came.

Similar to this is the difficulty which old people experience in learning
new bodily movements, that is, in associating new muscular actions, as in
learning a new trade or manufactury. The trains of movements, which obey
volition, are the last which we acquire; and the first, which are
disassociated.
