The solitary glands of the intestine, which occur bothin small and large, as well as their aggregations constituting thepatches of Peyer, which do not extend beyond the ileo-ceecal valve,are quite destitute of the follicular character, that is, agree onlyin name with those glands which are involutions of the generalmucous surface, invested by a lining of epithelium. They are Fig. l^g^^pffiffiBBT Vertical section of Peyerian patch, and solitary gland of larg-e intestine. The glands in both are rather enlarged. A, Peyerian patch from ileum. B, Solitary gland. simply solid ap:gTegated masses of nuclear particles and lymphaticcorpuscles, imbedded in a nucleated stroma, with very little inter-vening granulous matter, and lying completely beneath the sheetof basement membrane that covers the surface. They are notcontained in a distinct capsule of homogeneous membrane, but liepartly in the corium of the mucous tissue, partly in that layer ofnuclei and granulous matter which is spread under the basementmembrane, and forms the chief substance of the villi, to which wegave some years ago the name of substratum. It is apparentfrom this structural arrangement that they cannot be secretingorgans like the Lieberkuehn tubes all round them, for they haveno outlet. On the other hand, they are from their very structurepeculiarly liable to become
