experiment on animals to see in what
proportion iron is present in the sys-

the younger animals contain much
more iron than adults; In guinea pig
or rabbit one hour old, for instance.
there is more than four timea as much
iron as in the same animals two and .
half months old. He infers from this
that long-continued exclusive milk
diet is not good for babies, but should
be supplemented by wheat prepara-
