DR. J. G. PALMER:—I do not think I have anything in particular to say concerning rapid separation. I have the separator that Dr. Parr describes in his paper, and I also have a set of Dr. Perry's. The latter is, perhaps, the most nearly universal in its application of any. I cannot say that I agree with the doctor in regard to separating so rapidly in all cases: in some cases it is probably advisable to do it, but I would rather follow the lead of Dr. Faught's paper, and go a little slow. I think going slowly in separating teeth is as useful as it is in some other cases cited in the paper. DR. C. A. MEEKER:—I have used Dr. Parr's separator for three years, and prefer it to any of the others that I have used. DR. PINNEY:—Sometimes, when you have a couple of nice little teeth to fill, and you want to get to work and get it done, and you know your patient is going to be so nervous for a week after, if you put rubber between the teeth, that you cannot treat them, it is a great pleasure then to put on your separator and slowly and gradually get those teeth apart, with just one little squeal, so that you can put in your two fillings. This little instrument is one of the best things we have: it does not work in all cases, but it will in nearly all. It should be used carefully; you should not move the teeth in a second, or in a minute, but work carefully with it and you will be surprised to find how many times you can use a separator to advantage. Patients are better satisfied to have their teeth separated in this way, than be compelled to wear rubber or tape, or something of that kind, in the mouth—they say those things tire them.
