I have, however, met with a few instances where a sub-csecalpouch was present, and have even found the tip of the appendixinserted within k. In the unpublished notes of the 217 cases kindly sent me byDr. Kolleston, there are references to no less than 17 instancesof a distinct sub-csecal fossa, 13 being in males and 4 Fig. 9.—Sub-crecal Fossa. showiDg a Hernia of the Vermiform Appendix into it(Lockwood and Rolleston.)

The Mesentery of the Appendix. 31 In connection with these peritoneal folds brief referencemay be made to the meso-appendix, or mesentery of the vermi-form appendix. This structure is almost invariably present,although subject to considerable variation in length, thickness,and extent of attachment. It consists of a double fold of serousmembrane, and usually arises from the lower layer of the trueiliac mesentery. To the right
