ct, his country at
one bound found itself in the first rank in this department of natural
science. In Hauey's book are united in the highest degree two qualities
which are seldom associated. One of these is that it was founded on an
original discovery which had sprung entirely from the genius of its
author; and the other is that this discovery is pursued and developed
with almost unheard-of persistence down even to the least important
mineral variety. Everything in the work is great, both as regards
conception and detail. It is as complete as the theory it announces."

It was not surprising, then, that, after the death of Professor
Dolomieu, Hauey should be raised to the chair of mineralogy and made
director of that department in the Paris Museum of Natural History.
Here he was to have new triumphs. We have already said that his book
was noted for the elegance of its style and its perspicuity. {188} As
the result of this absolute clearness of ideas, and completeness and
simplicity of expression, Hauey attracted to him a large number of
pupils. Moreover, all those interested in the science, when they came
in contact with him, were so charmed by his grace and simplicity of
manner that they were very glad to attend his lectures and to be
considered as his personal friends. Among his listeners were often
such men as La Place, Berthollet, Fourcroy, Lagrange and Lavoisier.

It was not long before honors of all kinds, degrees from universities
and memberships in scientific societies all over Europe, began to be
heaped upon Hauey. They did not, however, cause any change in the
manners or mode of life of the simple professor of old times. Every
day he continued to take his little walks through the city, and was
very glad to have opportunity to be of assistance to others. He showed
strangers the way to points of interest for which they inquired,
whenever it was necessary, obtained entrance cards for them to the
collection; and not a few of those who were thus enabled to take
advantage of his kindness failed to realize who the distinguished man
was to whom they owed their opportunities. His old-fashioned clothing
still continued to be quite good enough for him, and his modest
demeanor and simple speech did not betray in any way the distinguished
scientist he had become.

Some idea of the consideration in which the {189} Abbe Hauey was held
by his contemporaries may be gathered from the fact that several of
the reigning monarchs
