NEW YORK, March 11.?There's a tl
new exhibit at the American Museum r
of Natural History athat tells a ffreat
deaf about teeth?about their struc- Jj
ture, location, mode of implantation,
prowth and replacement, with special J
reference to the teeth of mammrls. g
Many kinds of teeth are shown in the
exhibit, from the curious, complicated
apparatus called the "Aristotle's Iantern"
in vogue among the sea-urchins
to the great, cruel fang of the lion.
The Aristotle's lantern of thef seaurchin,
consists of five pyramidal jaws, j
each carrying a long slender tooth of t
continuous growth, which moves for- J
ward in the jaws as it becomes worn ]
away at the point. The horseshoe or j
king crab wears Jiis teeth on his legs, i
at the first joints of which is a series j
of spines and sharp points. The food |
is torn to bits on these teeth and !
worked into the mouth opening. The 1
lobster does his fletcherizing with ;
teeth which are to be found on his j
fourth to ninth appendages. Some of j
these teeth are adapted to seizing the I
food, others to grinding it. etc. The j
exhibit also reveals the little known :
fact that the beetle and worm boast ;
teeth as useful and efficient as any. j
Teeth of Backboned Animal.
Of course, there are teeth of many .
kinds. But the typical tooth of a
vertebrate or backboned animal consists
of (1) pulp contained in a cavity,
which by deposition of lime in its ex- ;
terior portion becomes (2) dentine. :
ivory or bone, forming the body of the 1
tooth. (3) enamel, overlaying the dentine
on the crown of the tooth, and
( ) cement, usually surrounding the
base of the tooth and sometimes cov
ering part or an ol toe enarnei i'i in<=
crown. The teeth of some animals. ;
however (the spbrm whale, for ex- i
ample), have no enamel whatsoever.
In man, as in most mammals, the j
teeth are set in distinct, separate ;
sockets, called by the initiated "alveolae."
and are separated by a membrane
from the surrounding bone. But
nature has other ways of implanting
teeth. The extiflct sea reptile known
to the scientists as ichthyosaurus had
his teeth planted in a continuous shalr \
low groove, as with certain birds
which lived many centuries ago. Mod- i
ern birds, however, have adopted the
fashion of going toothless. Some ani- I
mats have the advantage of teeth [
which are more or less movable, due ;
to the fact that they are attached
to the jaws by ligaments. This is the
case with many fishes and some rep- i
tiles.
Characteristics Explained.
Some animals. less fortunate than '
man. have only one set of teeth, which
are expected to last them through an j
entire lifetime. Most mammals, like
man. have two sets?a temporary or !
milk set and a* permanent set. No i
mammal has more than two sets of j
teeth. As a new tooth increases in :
size, the roots of the old one are
absorbed until finally it fails out and
gives place to the new. Most reptiles
and fishes, however, are well supplied
with teeth, having several series, !
which provides for a more or less
continnous loss and replacement. The I
rfhark Is not worried bjr the fear of a
toothless old age, for he has several
rows of teeth, one behind the other,
and as fast as the teeth in the outer
row are lost they are replaced by
hftfig 4nst hnrlr r\f thom ThZ tootk
of the elephant are developed at the
(trk of the jaw. and the entire row
IDCUt alowly forward, the front part
?f tpirh tooth coming into use'tirst
u4 wearing away as it la pushed for; ?,
* wurd While six teeth are developed
on each side of each jaw, not more 1
than parte of mo teeth are in use at |
any one time.
Hot All Wear Teeth in Mouths.
Not all animals wear their teeth in I
their mouths. As has been said, some ;
are partial to the location of their !
teeth on their legs, while others con- [
eider the stomach the ideal situation. I
And even among those animals where 1
the tooth's sphere Is the mouth there
are differences of opinion as to just [
were teeth can be worn with pro- 1
priety. The frog grows teeth only on I
his upper jaw. The animal known as j
Hoffman's sloth has teeth only on j
the hinder parts of both jaws. The :
gazelle's teeth are permitted to grow :
on both jaws, with the exception of j
the front of the upper jaw.
The teeth (or saw) of the sawfish,
far removed from the mouth, are designed
for wounding or killing the
prey. The teeth of the python are
made for . seizing and grasping, and
are recurved, so as to hold the prey
while the gullet is worked over it.
The teeth of the ray. which feeds
on shellfish, are adapted to crushing.
The lion's teeth are shaped for cutting,
rending and killing. The teeth
of the beaver are long, sharp and j
chisel-shaped?requisite tools for his j
life'3 work of gnawing. The fangs or
front teeth of the poisonous snake
are really tubes which serve as hypodermic
syringes tojnject the poison.
i ne eiepnant grindy his rood Detwpfit I
teeth whoBe roughened surfaces act j
like mill stones.
This information and very much j
more can be grained from an examina- J
tion of one little case on the fourth
floor of the American Museum, -where I
are gathered various teeth and jaws 1
tij a truly comprehensive exhibit of an
unusual sort.
The Illinois industrial survey com- j
mission has submitted a report recommending
'an eight-hour day and a !
forty-eight-hour week for woman :
workers. The report finds that em- j
ployers theifiselves are testifying to
the value of short hours of work for
woman employes.
