The capillary basement membrane: It has been pointed out in a previous paper (1) that the finest structures of this membrane cannot be demonstrated with this technique since they have very little affinity to osmium tetroxide. No certain changes of the basement membrane have been demonstrated in this material. It is possible, however, that it is thic- kened, and that there are structural changes in it, responsible for the increased permeability. References 1. BERGSTRAND, A., Laboratory Invest.
