ing scarce. Tooth-brush handles and cutlery handles are made of these
bones. The others in the skeleton are built of lime stuck together with
glue and molded into shape by the push and pull of muscles.

The soft bones of the head, shoulders, ribs, and breast do not need to be
so stiff as the bones of the legs; they have more glue in proportion to
lime than the leg-bones. The animal needs a kind of flexible,
weather-proof varnish flowed over it, so to speak, to protect the tissues.
Glue is what makes this coat or hide. So from bones and scraps and
trimmings of hide this glue or gelatin is soaked out. Even the bones on
which meat has been cooked have some little dribs of gelatin and fat in
them, and these are stewed under pressure until there is nothing left in
them of the gelatin, of which they now make the little capsules in which
the druggist puts the medicine whose taste we don't just fancy, and fats
which go to the soap-maker for the want of a better destination.

Drugs from Dead Cattle.

From the bodies of cows is obtained the tallow which is made into
oleomargarin.

The prevailing ailment of the American people is dyspepsia, which is due
to a natural lack of pepsin. But it has been found out that the pig's
pepsin will do as well as our own, so it is prepared for the drug-trade
and sold at considerably above the price per pound of the hog on the hoof.

There are all sorts of obscure nervous troubles which can be very
materially helped by a substance extracted from the gray matter of calves'
brains.

A growing child should make red corpuscles in his blood at a great rate.
All the processes which construct his bones and his flesh and his various
organs should be working full-powered. The red rib-marrow of freshly
killed young animals contains a substance which is soluble in chemically
pure glycerin and can be digested out of that red rib-marrow, and which,
if given to the child, greatly increases the proportion of red corpuscles
in the blood and stimulates all the constructive processes of the body.
This will sell for a much larger sum a pound than veal.

And so there are various other substances taken from the sweetbreads
proper, the neck-and-throat sweetbreads, the thyroid gland, the parotids,
and the suprarenal capsules which can be used in medicine and can be sold
at a large profit to people brought up to believe that "eating the part
strengthens the part."

Glycerin a By-Product.
