disturbance. He was called to Brooklyn, where they had a live society,
and an infirmary for the treatment of dental diseases, at which members
of the society were delegated to attend from day to day. He was invited
to give a clinic upon pyorrhea alveolaris, and he told them of this
patient, whom he showed to some fifteen members. The woman was
apparently in fair health. It was not loss of nerve-energy which started
the disease in this case, but the disease caused the loss of appetite
and the vitiated condition of the whole alimentary canal. Her physician
would have sent this woman to the grave, not recognizing the disease and
its management.

He maintains that it is not lack of nervous energy that causes this
disease, but the disease will lead to loss of nerve-energy. That small
purple ring on the gum of the cuspid in the case first mentioned would
eventually have led to the loss of the whole set, if left to work its
way unopposed. He had tried in these remarks to controvert the old
ideas, and to present the cause of the disease and its treatment as he
sees it. You may see it differently; if so, give us your information, in
order that we may correct our views, if wrong.

One gentleman says he finds it is only those who are strong and vigorous
who have this disease. The speaker finds some cases of this kind; he
also finds consumptives who have not a trace of it, but he would take
the strongest man in the room and cause a beautiful case of pyorrhea
alveolaris in his mouth in three weeks, with a fine cotton thread tied
around one of the lower front teeth at the line of the gum. The thread
will work its way under the gum, and the gum will become inflamed;
it will work its way down between the gum and the tooth, and in the
meantime the flour and the particles of food will also work down under
the loose gum, finding a rallying-point on the thread; the mass will
