upon the amount of flesh put in. The identity of the flesh would
be lost in a very short time. I have known Dr. Webster several
years. His general reputation is that of kindness and mildness.
By the Government. Should not think nitric acid would act on
mineral teeth. I have never tried it, though.
DR. Wm. T. G. MORTON, sworn. - I am a physician. Have prac-
tised dentistry about eight years. I usually manufacture my own
teeth. I have had opportunities of knowing Dr. Keep's work, and
have been instructed in his method of manufacturing teeth.
[Teeth shown.]
I see no particular mark by which to identify the teeth. I should
think they had been ground on the inside. It is not unusual to grind
out the inside, to make room for the tongue. It is done by small
wheels, from the size of a fourpence to a dollar. I have used pla-
tinum pins in my manufacture. It is not unusual. There are holes
in the plate, for the pins. There is no peculiarity in the position of
the holes. In a book I have recently read, it is laid down that the
best place is between the first bicuspid and the first molar, for the in-
sertion of these pins. There is partial absorption of the lower jaw.
I could take this mould and find teeth which would even fit better
than these shown me.
[Witness shows a tooth, and applies it to the mould.]
This fits on the right side, as to length. The general outline of
all jaws is alike.
[Witness showed some moulds where absorption is greater than
that seen in the mould of Dr. Parkman's mouth.]
Here is one with the same number of teeth, though not quite so
great an absorption. The block of teeth shown me look like teeth of
mine, when they fall into the furnace. There are some teeth which
I should think would be more likely to be found in the mouth than
others. We don't pull them, for they will often remain many years.
One is an eye-tooth.
These models I have shown are those of the most marked cases
that have occurred in my practice. On the application of great heat,
this block [found in the furnace] may have warped so as to fit this
mould of Dr. Keep's.
Cross-examination. I knew Dr. Parkman when he was alive. I
never saw any two jaws alike; so I cannot say anything about a
peculiar jaw. There is a general resemblance in all jaws, in some
parts. I couldn't say that his was peculiar.
I could give the names of those the models of whose jaws resemble
Dr. Parkman ; but I do not like to give the names of my patients.
In many instances, I could tell Dr. Keep's work; but would not swear
to every case. Teeth, when set and completed for one man, will not
fit another man's mouth. I should judge, from the mould, Dr. Park-
man was about fifty-five. I have one case here, where the absorp-
tion is as abrupt as in Dr. Parkman's; and here is another which
is not.
By Mr. Sohier. The blocks, separate and distinct, might fit two
mouths.
By Mr. CZiford. If I had a jaw to operate on, and had noticed
it, and had taken an impression, and that had any peculiar marks
