Note 17 — DISSERTATION II. CONTINUED.

This depends upon the operation of the sympathy of association. Sympathy was, in the preliminary dissertation, divided into that of association, and that of equilibrium; and it was mentioned, that the same parts might be made to exhibit either of these, but that naturally the sympathy of association is chiefly, and most easily exhibited by those parts which are similar in structure, and contiguous to each other; and, in them, the action spreads fastest. At the same time, if the action continues long, or be very strong, it may be propagated to dissimilar parts, and produce either a very extensive, or an universal action, which is just a greater degree of the sympathy of association. In this case, it has, however, been called universal sympathy.
