It is best and most convenient to examine the various struc- tures from within outwards. Beginning, therefore, with the epithelium, it is easy to distinguish at least four different kinds of cells—a columnar ciliated cell, a goblet or chalice cell, a more or less spindle-shaped or ovoid cell, and a rounded or cuboidal cell lying underneath, all resting above a clear, apparently homogeneous basement membrane. Fig, 1.—Epithelial Cells from the Human Bronchus. 1, 5, various forms of columnar cells. 2, goblet cells. 4, transitional cell. 9, cell from Debov^e's layer. (Nos. 3, 6, 7 and 8 are found in acute bronchitis, w'cZe.) (x 200.) into which some of the rounded cells of Debove's layer some- times appear to be slightly imbedded. With regard to the goblet cell, it is usually seen to taper to a narrow rounded extremity, and in this respect presents a striking contrast to its appearance generally in inflammatory conditions. It contains a nucleus which has become displaced downwards into a somewhat triangular area above its attached extrem- ity. These goblet cells are exceedingly prominent in this situation in the cat, sometimes attaining a great size and almost perfectly globular, or even of greater breadth than
