Treatise on the radical cure of hernia by instruments : embracing an analysis of the mechanical properties of the various trusses now in use, a description of the new instruments invented by the author, and general directions to patients for the safe employment of these instruments, with hints to surgeons in their application, requisite in this instance^ and the block should be con-structed so as to act mainly on the external ring, socalled. But this ring is in fact a triangle, with thebrim of the pelvis, or the edge of the pubic bone form-ing one of its sides. In order, then, to prevent all dangerof dilation, the block must be large; and, for the pur-pose of completely covering the ring, it must approachas nearly as possible to the brim of the pelvis. Dr. Hood had two contrivances for this purpose, oneof which he called his ventro-inguinal block, and theother his scrotal block. In the Report of the Commit-tee they are both called ventro-inguinal blocks. The ilrst of these was decidedly condemned by theCommittee. It is concave on its pressing surface, and isliable to the censure passed upon all the concave pads,in the section on forms. The second is by far the bestof the blocks mentioned in Dr. Hoods is seen with its sections in figs. 17, 18, and 19. Fig. 17.—HOODS VENTRO-INGUINAL Fig. 18—Transverse 19.—Longitudinal section. Until after the Report of the Committee, I had notcompleted my own ventro-inguinal block, and I employ- 80 WOODEN ed this contrivancej considerably modified, in all badcases of ventro-inguinal rupture—though, in many in-stances, my common inguinal block was used. In relation to this contrivance, the Committee makethe following remarks. The best idea of the peculiar form of this block isconveyed by supposing the upper surface of the commonsoft pad of an ordinary truss, (i. e. the pad of the commontruss, fig. 4, p. 45) to be compressed until it be made tooverhang its base upon the
