12 PATHOLOGY OF THE HARD TISSUES OF THE TEETH.

tion, and has arrived at the conclusion that there is no special
form of disease that is especially blamable for this affliction, but
that any form of disease that seriously interferes with nutrition
is liable to bring about this result, i. e., that it is not the partic-
ular form of disease, Imt that it is the condition of malnutrition
that is the cause, no matter what the disease which has induced
that condition. I have seen eases of typical Hutchinson teeth
which were certainly in no way connected with a syphilitic taint
of any kind.
Some of these observations may be of interest. Mr. and Mrs.
B., known by the author intimately from childhood, had a child
which seemed healthy at birth, but soon afterward became anemic
and did very badly for two years. Growth was a failure during
that time, and it was with great difficulty that the child was kept
alive. In its third year, however, the child recovered and became
strong and healthy and developed well. When the permanent
teeth came through the gums, almost the iucisal third of the cen-
trals and laterals was badly dwarfed, the points of the cuspids
had failed and the occlusal surfaces of all of the first molars
were badly atrophied.
In another case a kinswoman was visiting at my house with
a little girl two and a half years old. The child had not been very
well for some time, though she showed no particular form of ill-
ness. She would play much of the time, but seemed to get very
tired. One day I was suddenly called to her and found her appar-
ently dead, a condition that had been preceded by a violent clonic
spasm. I instituted artificial respiration at once, and after a few
moments there was a sigh and directly another, and within a few
minutes the respiration and circulation were reestablished. The
child dropped to sleep almost immediately, while yet in my arms,
and seeing that the breathing was sufficiently full and regular,
I laid her on a couch and left her mother to watch her. She slept
three hours, and when she awoke she was ready to play again.
She remained rather dull for a month, when the condition seemed
to pass away. There was l)ut the one spasm. But when the per-
manent teeth came through they were dceph' marked, corre-
sponding with the time of this occurrence.
I attended a eliild two and a half years old through a severe
case of typhoid fever. When the permanent teeth came through
they were marked with a deep groove, irregularly pitted, similar
to Figure 3, but not so high u)) on the crowns.
An English woman broiiglit lier child to me on account of
a very ugly marking of the incisors which had just (-omc through
