QUALITIES OF IVORY 225

through had formed around the bullet. Among the numerous interior
growths several cuplike hollow masses are to be noted, one of these
being 4| in. across, 4 in. high and 3-1/2 in. wide. In still another
example a tusk measuring 6 in. across contained certain rounded growths
of a whitish or yellowish dentine in which could be observed very small
globular masses of a pronounced yellow. These minute globules were of
an almost saffron yellow, apparently striated, and represented a
different or subsidiary growth to that of the main mass. These
specimens afford good evidence that many elephants are struck by shots
but are not killed. In other words, judging from the number of tusks
showing encysted iron or lead bullets, it is self-evident that these
were not the bullets that ended the animal's life; of course the
wounding of the tusk would at most give an elephant a powerful shock,
and unless the shot that hit the tusk were closely followed by another
to the brain, the animal would escape practically uninjured, and when
the tusk has been traversed by the ball the direction usually
indicates that it could not have inflicted a mortal wound even if its
momentum were not too much lessened by the resistance of the ivory it
had passed through. Instances of recent shooting showed that the ball
had shattered the tusk and this had regrown, thereby proving that the
bullet in question had not been that which had killed the elephant.
Of
the irregular masses of exostotic ivory, one was 5 in. long and weighed
3 pounds. One of these growths resembled a seahorn. In one instance the
tusk showed a large opening, beginning at its outer edge, running well
into it and making a hollow space; this was apparently due to disease.
In several examples a growth was to be seen extending across from one
side of the tusk to the other, forming a sort of Siamese-twin ligature.
