masses of dental tissue. Here all semblance to normality 
ceases and the process of dentition runs riot. The affected side 
of the face is enormously enlarged, as seen in Fig. IV, the 
facial bones, especially the superior maxillary, greatly bulged, 
soft and porous, while the specific gravity of the mass is greatly 
increased owing to the enormous amount of dental tissues, the 
affected side being four or five times as heavy as the normal. 
Three large almost globular masses of fine, delicate porous 
bone (Fig. II, E, C and B) apparently represent the turbinated 
bones. The bony palate (Fig. II, H H) has been separated into 
two distinct layers and the space between occupied by loose 
cancellated bone, in which are imbedded numerous denticles, 
many of which penetrate through the bony palate, as seen at 
A, Figs. II and III, but had evidently not perforated the buccal 
mucous membrane. 
Occupying the large caverns in the globular masses of 
spongy bone mentioned above as probably representing the tur¬ 
binated bones, and behind the three masses in a fourth spheroi¬ 
dal cavity, are enormous irregular masses of dental tissue, chiefly 
ivory, rough, with sharp denticles or spurs, presenting in every 
direction like cockle-burs and weighing probably one pound 
each. The masses within the cavities of the sponge-like bones, 
B and C, Fig. II, do not show in photograph, while that of E 
is clearly shown at D, and the fourth cavity looking backwards 
shows a border of its denticular mass at F. 
In addition to these masses the donor related that u thou¬ 
sands of little bones had dropped out ” before the specimen was 
given into our care. These were no doubt denticles, as many 
yet remain, a few of which are shown in Fig. V. These take 
on curious and fantastic shapes; they are straight, curved, spi¬ 
ral, like a ram’s horn, single, double, multiple, linear, globular. 
Some are quite perfect representatives of teeth in a general way, 
having a well-marked pulp cavity, around which are grouped in 
their normal sequence dentine, enamel and cement. Others, 
like the central mass in lug. V, are indescribable irregular 
bunches of dentine or cement. Still other denticles are seen
