Catherine. He was
librarian to the Elector of Mainz when the French Revolution broke out,
and was sent as a deputation to Paris by the republicans of that town,
who desired union with France. He died at Paris in 1794. His prose is
considered classical in Germany, having the lightness of French and
the power of English gained through his large knowledge of those
literatures.

[84] It is to be regretted that Froebel has not developed this
point more fully. He speaks of "die Betrachtung des Zahlensinnes in
horizontaler oder Seiten-Richtung," and one would be glad of further
details of this view of number. We think that the full expression
of the thought here shadowed out, is to be found in the Kindergarten
occupations of mat-weaving, stick-laying, etc., in their arithmetical
aspect. Certainly in these occupations, instead of number being built up
as with bricks, etc., it is laid along horizontally.

[85] Carl Christian Friedrich Krause, an eminent philosopher, and the
most learned writer on freemasonry in his day, was born in 1781. at
Eisenberg, in Saxony. From 1801 to 1804 he was a professor at Jena,
afterwards teaching in Dresden, Goettingen, and Munich, at which latter
place he died in 1832.

[86] Lorenz Oken, the famous naturalist and man of science, was born at
Rohlsbach, in Swabia, 1st August, 1779. (His real name was Ockenfuss.)
In 1812 Oken was appointed ordinary professor of natural history at
Jena, and in 1816 he founded his celebrated journal, the _Isis_, devoted
chiefly to science, but also admitting comments on political matters.
The latter having given offence to the Court of Weimar, Oken was called
upon either to resign his professorship or suppress the _Isis_. He
chose the former alternative, sent in his resignation, transferred the
publication of the _Isis_ to Rudolstadt, and remained at Jena as a
private teacher of science. In 1821 he broached in the _Isis_ the idea
of an annual gathering of German _savants_, and it was carried out
successfully at Leipzig in the following year. To Oken, therefore, may
be indirectly ascribed the genesis of the annual scientific gatherings
common on the Continent, as well as of the British Association for the
Advancement of Science, which at the outset was avowedly organised after
his model. He died in 1851.

[87] Those acquainted with the classical mythology will forgive us for
noting that Charybdis was, and is, a whirlpool on the Sicil
