ated into French two of his Latin works under the titles
_L'Aurore naissante, ou la Racine de la philosophie_ (1800), and _Les trois
principes de l'essence divine_ (1802). The originals had appeared nearly
two hundred years earlier,--_Aurora_ in 1612, and _De tribus principiis_ in
1619.

[372] "Unknown."

[373] "Skeptical."

[374] "Man, man, man."

[375] "Men, men, men."

[376] It is interesting to read De Morgan's argument against Saint-Martin's
authorship of this work. It is attributed to Saint-Martin both by the
_Biographie Universelle_ and by the _British Museum Catalogue_, and De
Morgan says by "various catalogues and biographies."

[377] "To explain things by man and not man by things. _On Errors and
Truth_, by a Ph.... Inc...."

[378] "If we would preserve ourselves from all illusions, and above all
from the allurements of pride, by which man is so often seduced, we should
never take man, but always God, for our term of comparison."

[379] "And here is found already an explanation of the numbers four and
nine which caused some perplexity in the work cited above. Man is lost in
passing from four to nine."

[380] Williams also took part in the preparation of some tables for the
government to assist in the determination of longitude. He had published a
work two years before the one here cited, on the same subject,--_An entire
new work and method to discover the variation of the Earth's Diameters_,
London, 1786.

[381] This is Gabriel Mouton (1618-1694), a vicar at Lyons, who suggested
as a basis for a natural system of measures the _mille_, a minute of a
degree of the meridian. This appeared in his _Observationes diametrorum
solis et lunae apparentium, meridianarumque aliquot altitudinum cum tabula
declinationum solis_.... Lyons, 1670.

[382] Jacques Cassini (1677-1756), one of the celebrated Cassini family of
astronomers. After the death of his father he became director of the
observatory at Paris. The basis for a metric unit was set forth by him in
his _Traite de la grandeur et de la figure de la terre_, Paris, 1720. He
was a prolific writer on astronomy.

[383] Alexis Jean Pierre Paucton (1732-1798). He was, for a time, professor
of mathematics at Strassburg, but later (1796) held office in Paris. His
leading contribution to metrology was his _Metrologie ou Traite des
mesures_, Paris, 1780.

[384] He was an obscure writer, born at Deptford.

[385] He was also a writer of no scientific merit, his
