of blood corpuscles would appear to be partially due to clotting, and also to the fact that the sheath appears to be continued in a transverse direction across the enamel organ. When a true vertical section is procured it is seen that the vascular tubes are surrounded by cellular elements arranged exactly like a simple tubular gland (figs. 106 and 107), and that within the centres of these gland-like structures channels are visible filled with granules, these channels becoming approximated below and passing into a similar delicate stroma to that seen inSargus intervening between the enamel organ and the forming enamel. This apparatus would apparently serve the same purpose as the somewhat identical arrangement in the enamel organ of Sargus, conveying the lime salts elaborated in these gland-like structures from the blood-
