of Europe, as well as the heirs apparent to many
thrones, came at some time or other to visit him, to see his
collection, and to hear the kindly old man talk on his hobby. There
was only one other scientist in the nineteenth century--and that was
Pasteur, toward the end of it--who attracted as much attention from
royalty. Among Hauey's visitors were the King of Prussia, the Emperor
of Austria, the Archduke John, as well as the Emperor of Russia and
his two brothers, Nicholas and Michael, the first of whom succeeded
his elder brother, Alexander, to the throne, and half a century later
was ruling Russia during the Crimean War. The Prince Royal of Denmark
spent a portion of each year for several years with Hauey, being one of
his intimates, who was admitted to his room while he was confined to
his bed, and who was permitted to share his personal investigations
and scientific studies.

His most striking characteristic was his suavity toward all. The
humblest of his students was as sure to receive a kindly reception
from him, and to have his difficulties solved with as much patience as
the most distinguished professor in this department. It was said that
he had students of all classes. The attendants at the normal school
were invited to visit him at his house, and he permitted them to learn
all his secrets. When they came to him for a whole {190} day, he
insisted on taking part in their games, and allowed them to go home
only after they had taken supper with him. All of them looked upon him
as a personal friend, and some of them were more confidential with him
than with their nearest relatives. Many a young man in Paris during
the troublous times of the Revolutionary period found in the good Abbe
Hauey not only a kind friend, but a wise director and another father.

It is said that one day, when taking his usual walk, he came upon two
former soldiers who were just preparing to fight a duel and were on
their way to the dueling ground. He succeeded in getting them to tell
him the cause of their quarrel, and after a time tempted them to come
with him into what I fear we should call at the present day a saloon.
Here, over a glass of wine, he finally persuaded them to make peace
and seal it effectually. It is hard to reconcile this absolute
simplicity of character and kindness of heart with what is sometimes
assumed to be the typical, distant, abstracted, self-centered ways of
the great scientist.

Few men have had so many pr
