    412 breadth glands, the ducts (gl. d.) of the latter opening at the bottom of the furrow. In the walls of the furrow are seven or more tiers of taste-bulbs {t. b.). The bulbs vary in shape, but most of them possess more or less of a neck. They average about 0,0G0 mm in length and 0,030 mm in breadth. The peripheral ends of the sensory cells (of which there appear to be about sixteen in a well-developed bulb) are highly refractive, and project freely through the pore into the furrow. The basal half of many of the bulbs rests entirely 'in the mucosa, and is fre- quently bent somewhat downwards. Non-medullated nerves approach the furrow from the sides, and their terminal branches can be followed directly to the bases of the bulbs. The organ bears a striking resemblance to the duct of a gland, and doubtless represents the papilla foliata in its simplest form. Amherst, Mass., 11. May 1889.
