A system of surgery : pathological, diagnostic, therapeutic, and operative . mbrane before them,may involve the whole circumference of the tube, and extend several lines oreven inches up and down in the direction of its length. Having remainedstationary for an indefinite period, the deposit manifests a disposition to soften-ing and disintegration, and is ultimately converted into a curdy, friable, or, moreproperly speaking, a pap-like substance, possessing, apparently, all the proper-ties of scrofulous pus. At this stage of the disease, the lining membrane is oftenelevated into small pustules, or little abscesses, which, bursting, discharge theircontents into the blood, thus leaving a corresponding number of ragged andirregular ulcers, the base of which is formed by the middle tunic. The fatty deposit is most common in the aorta, particularly its thoracic por-tion, near the origin of the great cervical trunks. Its occurrence is almostpeculiar to the aged. What the causes are, under whose influence it is devel- CHAP. v. INTRA-PARIETAL SEPARATION, 665 Fiff. Fatty granules, with crystals of choles-terine, from atheromatous deposits iu theaorta. What treatment might accom- oped, has not been ascertained. That it is occasionally connected with imperfectalimentation, and the inordinate use of ardent spirits, is unquestionable, butthat these circumstances are essential to its production, as some pathologistscontend, cannot be admitted ; because the disease, as is well known, has fre-quently been witnessed in the stoutest andmost temperate subjects, a fact which is entirelyat variance with such a conclusion. Under the microscope the atheromatous mat-ter is observed to consist of albuminous andearthy particles, of crystalline plates of choles-terine, of an imperfect fibrous texture, and ofoil globules. The amount of fatty substanceis frequently so great that it imparts a greasystain to paper when dried on it by heat. Theminute appearances of this deposit are wellshown
