"Fleas, flies, and friars, are masters who sadly the people abuse,
And thistles and briars are sure growing grains to abuse.
O Christ, who hatest strife and slayst all things in peace,
Destroy where'er are rife, briars, friars, flies and fleas.
Fleas, flies, and friars foul fall them these fifteen years
For none that there is loveth fleas, flies, nor freres."

[668] "It is my plan to restore to an unskilled race the worthy arts of a
better life."

[669] The first sentences of the first oration of Cicero against Catiline:
"Quo usque tandem abutere, Catilina, patientia nostra?" (How long, O
Catiline, will you abuse our patience?) "Quamdiu etiam furor iste tuus nos
eludet?" (How long will this your madness baffle us?) "Nihilne te nocturnum
praesidium Palati, ... nihil horum ora voltusque moverunt?" (Does the night
watch of the Palatium, ... do the faces and expressions of all these men
fail to move you?) "In te conferri ..." (This plague should have been
inflicted upon you long ago, which you have plotted against us so long.)

[670] "Beware of the things that are marked."

[671] "Farewell, ye teachers without learning! See to it that at our next
meeting we may find you strong in body and sound in mind."

[674] This proof, although capable of improvement, is left as in the
original. Those who may be interested in the mathematics of the question,
may consult F. Enriques, _Fragen der Elementargeometrie_ (German by
Fleischer), Leipsic, 1907, Part II, p. 267; F. Rudio, _Archimedes_,
_Huygens_, _Lambert_, _Legendre_. _Vier Abhandlungen ueber die
Kreismessung_, Leipsic, 1892; F. Klein, _Famous Problems of Elementary
Geometry_ (English by Beman and Smith), Boston, 1895; J. W. A. Young,

[677] Joseph Allen Galbraith who, with Samuel Haughton, wrote the Galbraith
and Haughton's _Scientific Manuals_. (Euclid, 1856; Algebra, 1860;
Trigonometry, 1854; Optics, 1854, and others.)

[678] This note on Carlyle (1795-1881) is interesting. The translation of
Legendre appeared in the same year (1824) as his translation of Goethe's
_Wilhelm Meister_.
