Sure enough, the kittens teeth were

ing. That's the way bird fanciers claim
they make red canaries. The process of
coloring the bones and teeth of kittens is
the simplest thing in the world. All
there is to it is to put little madden in
their food"
'But doesn't the madden injure them?'
the reporter inquired.
"Not in the least, said the doctor. 1T
is vegetable coloring matter and has no
injurious effect on the general health
whatever. This has been proven even in
the case Of children"
"Why," asked the reporter, "has some
one been feeding babies on madden to
give them pink teeth?"
''Oh, no." the doctor laughingly re-
piled, "but when the discovery was mado
that madden, when taken into the sys-
tenn, died the osseous structure, it was
thought it might prove efficacioas in the
treatment of ricketts,. Experiments were
tried with it on rickety children, but it
was found that while it readily took
the place of phosphate of lime in bone
formation, it did not improve the quality
of the bone"
Then all the bones of the body are
colored by the madden as well as the
teeth" the reporter inquired.
Certainly" the doctor answered. II

and on removing the cover a strong odor
of camphor saluted the reporters nose.
There, said he, taking up a section of
bone, lis the fragment of the skull of q
kitten which was fed on madder for ten
days and then allowed to go without
madden for six weeks or Sc, when it was
killed. The streak of pink in the center
Of the bone indicates the bone growth
during the period which the kitten was
taking madden. The streak of pink is
faint, you see, and would have disap-
peared entirely if the kitten had been al
lowed to live while longer. The bone
back Of the ear, you notice, is of a deep
pink color. That is due to the
fact that that portion of the skull
becomes mature sooner than the
rest. In young animals, you know, the
bony structure undergoes rapid changes.
After maturity is reached the changes
are slower. A pigeon, for instance, at
tains full growth after thirty days. Now
if, when pigeon is ten days old you be-
gin to feed it on madden, keeping it up
five days and then stop, by the time it
attains maturity all the color taken up
by the osseous structure will have en-
tirely disappeared. By thus experiment
ing with madden some important facts
regarding the growth OF the bones have
been ascertained"
"IIas the fact that madden will color
the bones been known long2"
about thirty years, think. 1t was
discovered accidentally by French ply
sician, who resided in town where a
factory for making the red cloth for SOL
diers' trousers was located. Madden is
used in dying this cloth. 1t was found
that pigs killed in tho town had their
bones died a brilliant pink. This curious
circumstance attracted the attention of
the physician, who began an investiga-
ton. He found that pigs drank waste
water from the dye room of the factory,
and this gave him the explanation Of
their pink bones. Washington Star.
