earth, Armenian bole, draggon's blood, carmine, redlake, &c. :
crocus gives to a tooth powder, a pretty color.

Either of the above forms may be used with advantage,
when the gums are diseased : directions for the use of astring-
ents have been given under the subject of scurvy in the gums.
(See page 143.) Tooth powders or washes cannot be of much
service in the cure of diseased gums, unless the causes of the
disease be previously removed.
In conclusion of this subject, we make the following extract
from Mr. Snell's work on the teeth, page 199.
"Almost all the tooth powders prepared for the shops are
injurious, and deserve public censure in a similar manner to
what took place in Paris, in 1793. A tooth powder to be
popular, must make the teeth white : this is usually accom-
plished by the use of acids. Many dentists make a great
secret of their compositions. No man of science can be de-
ceived by such charlatanism.
