animals ; and, as was observed above, when soaked in a gentle
acid, there appears no gristly or fleshy part, with which the
earthy part had been incorporated.*

* In all these experiments I never could observe, that the Enamel
was in the least tinged, either in the growing or formed Tooth. This
looks as if the Enamel were the earth more fully depurated, or strained
off from the common juices in such a manner, as not to allow the gross
particles of madder to pass. Here it may not be amiss to remark, that
the names given to animal substance, such as Gluten, &c. are not in the
least expressive of the thing meant ; for there is no such thing as glue
in an animal, till it has either undergone i putrefactive process, or been
changed by heat. And here too I woidd be understood, that I call
earth no part of an animal ; nor does it make up any part of an animal
substance.
