the enamel which does not yield the pounds pressure
you put on the tooth is almost double with a blow of similar
momentum. Just so if you are chipping enamel with the
chisel and mallet ; when the enamel chips off readily you may
strike a rather hard blow, but if you catch your chisel a
little too far on the tooth and it doesn't yield, you hurt your
patient you increase the pounds blow loo per cent.

I hope you will get something from this that will be of
value to you.

Special Infirmary Work.

I have asked the members of the Senior Class, indeed^
made it a part of the requirements of them, that they each

make, under my immediate supervision, Dr. Birkland and
Dr. Macfarlane assisting me, two gold fillings and two
amalgam fillings, one of each to be completed before the 15th
of January, and the remaining two before the 15th of April.
I will further require that a written description of each step
of the process, from beginning to completion, be handed me,
or to one of the assisting demonstrators, within one week
after making such filHngs. I will also require that I or one
of my assistants see the case before the beginning and at
various steps of its progress.
These requirements are made with the intention and
purpose of inducing you to think closer of the individual
steps of the process of preparing cavities in teeth, and in
placing fillings, and I am of the opinion that if you enter
heartily into this work, do these fillings and write these de-
scriptions, you will find it one of the most profitable exer-
cises of your school year. Of course, percentage markings,
will be given on this work. I shall require no impossibili-
ties of you, but wish you to do your best.
Points to be noted in writing descriptions:
1st. Age of patient (about, or your judgment).
2d. Condition of gums and peridental membrane.
3d. Apparent. habitual condition of the patient's teeth as
to care and cleanliness.
4th. Apparent progress of decay of teeth.
5th. Form of the teeth (bell crowned, medium form^
thick necked).
