From all this, then, it would appear that the con-solidation and cure of an aneurism by compression may and does takeplace in three different ways : 1, by the slovv deposit of laminated fibrine ;VOL. If.—5. 66 ANEURISM. 2, by rapid coagulation of the contents of the sac; 3, by contraction ofthe sac. The particular mode of cure will depend upon the completenessof the compression and the more or less perfect arrest of the blood inthe sac, the plasticity of that blood, and the shape of the aneurism. Circumstances influencing Success.—The success of the treatment bycompression depends greatly upon a scrupulous attention to a number ofminor circumstances, which, though each be trifling in itself, become ofimportance when taken as a whole. During the whole of the treatment,also, the patients general health should be attended to in accordancewith those dietetic and medical principles that have already been laiddown in speaking of tlie constitutional treatment of the disease, having fortheir object the increase of the fibrination of the blood.
