Abstract

In the description of figure 29 in an earlier account of "Ossification of the Otic Capsule in Human Fetuses,"1 reference was made to a peculiar process of resorption of part of the cartilaginous otic capsule, in the canal region, by means of vascular connective tissue buds without any attempt at ossification. Again in a paper on the "Blood Supply of the Otic Capsule,"2 the arteries were enumerated and traced that are concerned in the formation of the vascular connective tissue buds responsible for the resorption of the massive cartilaginous capsule in the region of the semicircular canals. In his excellent injection preparations Dr. George Shambaugh saw the numerous vessels in the canal region of the otic capsule in calf fetuses and pictured them in his paper on "Verbindungen zwischen den Blutgefässen in dem membranösen Labyrinth und dem Endosteum und den Gefässen in der knöchernen Labyrinthskapsel."3 Resorption
