have to struggle under the burden of life as cripples, or with injured
limbs."

"Just so," replied Paula. "Nothing can be more truly merciful than to
render life bearable to such hapless beings. . . ."

"But still, you think," interrupted the eager old man, "that this noble
motive alone would hardly account for the old oddity's riding his hobby
so hard.--Well, you are right. From my earliest youth the structure of
the bones in man and beast has captivated me exceedingly; and just as
collectors of horns, when once they have a complete series of every
variety of stag, roe, and gazelle, set to work with fresh zeal to find
deformed or monstrous growths, so I have found pleasure in studying every
kind of malformation and injury in the bones of men and beasts."

"And to remedy them," added Philippus. "It has been his passion from
childhood.

"And the passion has grown upon me since I broke my own hip bone and know
what it means," the old man went on. "With the help of my fellow-student
there, from a mere dilettante I became a practised surgeon; and, what is
more, I am one of those who serve Esculapius at my own expense. However,
there are accessory reasons for which I have chosen such strange
companions: deformed slaves are cheap and besides that, certain
investigations afford me inestimable and peculiar satisfaction.
But this cannot interest a young girl."

"Indeed it does!" cried Paula. "So far as I have understood Philippus
when he explains some details of natural history. . . ."
