ley, of Newburyport, use the same materials, and in nearly the same
way, as Dr. Keep. All mineral teeth are made of nearly the same
substances-quartz, felspar, and fine white clay; but they differ in
their proportions of these materials. Dr. Keep's teeth are almost
destitute of white clay. This work appears to have been done by Dr.
Keep. I am quite confident that it is Dr. Keep's style and composition.
When he manufactures blocks of teeth, he does not separate each tooth
down to the gum, as I do ;but he leaves them connected together,
probably for the purpose of giving them greater strength. I know Dr.
Keep's work, from having seen it in the mouths of patients, and some-
times at his place. I don't say that Dr. Keep's style is his alone. His
style is not to separate the teeth far from their edge or point. ['Models
shown.] I should think, from the absorption of bone at one part on
the left - [Objected to, as not being proper for rebutting testimony
and the Court ruled that it was not, of course, admissible to go into
general testimony now ; but that it was proper to state the peculiari-
ties upon which to ground judgment.] If I had the moulds, and if I
had made the teeth, and if I had seen them a short time before, I should
know teeth that I had made. I think Dr. Keep could not have been
mistaken. [Here the witness stated that since handling the block
shown him, a portion of the top of a tooth had come off, thus showing
the original composition.]
I should not conceive how he could have been mistaken, unless
there were duplicates of the set.
Cross-examination. The block has a peculiarity; has a projection
below the molar teeth, which corresponds to an extraordinary absorp-
tion. From this, as well as the general workmanship and style of
making, I should know then, if they were mine, even in such a
condition. I think there are several gentlemen who make teeth in
blocks, but in a different way. I have seen blocks something like that.
I have looked over two bushels of models, but have not seen any so
marked and so peculiar. From the circumstances I have stated, I do
not think that the maker of these teeth could have been mistaken.
Ds. JOSHi1A TUCKER, szvorn.-I am a dentist, in this city. I have
received a medical education, and have been in the practice of den-
tistry twenty-one years; and have been employed all the time. I have
given attention continually to artificial teeth, and manufacture sets, as
well as single teeth. [The block of teeth found in the furnace
here shown.] I should not like to give any opinion on any but the
left lower block, and that I should think could be identified by a dentist.
I think the dentist who made it could identify it as easily as an
artist, who had spent a week in painting a man's face on canvass,
would recognize the picture painted by himself.
Cross-examination. I should think, in connection with a model.
a man could identify his work. If a man made the teeth, and had
the model from which he made them, then I should think he might
identify them. I would not say that they might not be warped into
shape by heat.
DR. WILLARD W. CODD'LAN, sworn. - I am a dentist. I have received
medical education, and have been connected pretty largely with
dentistry, for about fifteen years; part of that time I wrought upon
mineral teeth entirely. [The teeth found in the furnace shown to the
witness.] I think they furnish sufficient means of identification.
