Note 54 — DISSERTATION II. CONTINUED. (continued 2)

The degree of pressure necessary for producing this effect is proportioned to the susceptibility of the granulations, or organic particles, for receiving the impression of being in contact. When a part is healthy, the mere circumstance of juxtaposition is sufficient for this purpose; and, in a healthy ulcer, the weight of the body applied, such as powdered chalk, or plaster of Paris, or at least the gentle pressure of a stocking, or easy bandage, is all that is necessary. But, when the action is too low, and the granulations are consequently imperfect, both in their structure, power of acting, and capability of receiving impressions, the contact, in order to operate, must be nearer, and more complete; or, in other words, the pressure must be greater. In these cases, bandages not only act on the surface, but also on the parts below, and, therefore, increase the degree of contact of the newly-formed organic particles, and thus strengthen the part.
