234 THE MICRO-OROANISMS OF THE HUMAN MOUTH. ;
penetrate to the vulnerable point. K this is conscientiously
done, I think that we have in solution ITo. 4, and, in a less
degree, in the other solutions specified, a powerful means of
preventing the excessive ravages of decay. The solutions 1 and
4 may be made use of in the following form
Xo. 1. Thymol 0.25 grams.
Benzoic acid . 3.00 "
Tincture of eucalyptus . 15.00 "
Alcohol . 100.00 "
Oil of wintergreen . 25 drops
(or oil of peppermint . . 20 " )
In use, enough of this mixture is added to a mouthful of
water to produce a decided cloudiness.
The wash, no doubt, may be rendered softer and more palat-
able by the addition of glycerine, tincture of catechu, or some-
thing of the kind. Perhaps some one who is interested in
mouth-washes will kindly undertake the task.
No. 4 is prepared in the same way, with the addition of 0.8
bichloride of mercury
Acid, thymic. , 0.25
Acid, benzoic. . 3.00
Hydrarg. bichlorid. . 0.80
Tinct. eucalypt. . . 15.00
Alcohol absolut. . 100.00
01. gaultherise gtt. XXV
One naturally hesitates to prescribe a mouth-wash which con-
tains bichloride of mercury, but I think a more thorough con-
sideration of the question will show that it is not so reprehensible
an act as may at first appear.
The strength in which the bichloride is used in the mouth is
about -joVo- ^^^ ^^^ suppose that the patient swallows of the
solution two grams daily (as a matter of fact, one need not
it would require one hundred days to have
swallow any at all) ;
swallowed 0.1 gram of the salt, which is the maximum dose for
one day. In this matter, however, reasoning is of little value
