the same
year Dr. Zeitman, of Germany, recommended it as a substitute for gold,
particularly for poor people.

"Is tin foil poisonous? If not, why are our brethren so reluctant to use
it? Is it nauseous? If not, why not employ it? Will it not preserve the
teeth when properly used? Then why not encourage the use of it? Does its
name signify one too common in the eyes of the people, on account of its
daily use in the tin shops, or do patients murmur when the fee is
announced, because it is nothing but tin? Is it not better than amalgam,
although the patient may believe it less costly? Eleven good plugs,
twenty-nine years old, in one mouth demonstrates that tin will last as
long as gold in many cases." (F. A. Brewer, _Dental Cosmos_, 1863.)

"So much tin foil is used for personal and domestic purposes that the
following is important: Ordinary tin foil by chemical analysis contained
88.93 per cent. of lead; embossed foil, 76.57 per cent.; tea foil, 88.66
per cent.; that which was sold for the pure article, 34.62 per cent. Tin
foil of above kind is made by inclosing an ingot of lead between two
ingots of tin, and rolling them out into foil, thus having the tin on
the outside of the lead." (Dr. J. H. Baldock, _Dental Cosmos_, 1867.)

The author used tin foil for filling the teeth of some of his
fellow-students at the Ohio College of Dental Surgery in 1867.

"Amalgam should never be used in teeth which can be filled with tin, and
most of them can be." (Dr. H. M. Brooker, Montreal, 1870.)

"I have used tin extensively, and found it more satisfactory than
amalgam. Dentists ignore tin, because it is easier to use amalgam, less
trouble. This is not right. If your preceptor has told you that amalgam
is as good as tin, and he thinks so, let him write an article in its
defense. Not one dentist in ten who has come into the profession within
the last ten years knows how to make a tin filling, and only a few of
the older ones know how to make a _good_ one." (Dr. H. S. Chase,
_Missouri Dental Journal_, 1870.)

"Among the best operators a more general use of tin would produce
advantageous results, while among those whose operations in gold are not
generally successful an almost exclusive use of tin would bring about a
corresponding quantum of success to themselves and patients, as against
repeated failures with gold. The same degree of endeavor which lacked
success with gold, if applied to tin would produce good results and save
