CLAIRAU'LT (Alexis-Claude), a celebrated French 
mathematician and academician, was born at Paris the 
13th of May 1713, and died the 17th of May 1765, at fif¬ 
ty-two years of age. His father, a teacher of mathematics 
at Paris, was his lole inftrudtor, teaching him even the 
letters of the alphabet on the figures of Euclid’s Elements, 
by which he was able to read and write at four years of 
age. By a fimilar llratagem it was that calculations were 
rendered familiar to him. At nine years of age he put 
into his hands Guifnee’s Application of Algebra to Geo¬ 
metry ; at ten he ftudied PHopital’s Conic Sedtions ; and, 
between twelve and thirteen, he read a memoir to the aca- 
dem)'- of feiences concerning four new geometrical curve's 
of his own invention. About the fame time lie laid the 
firft foundation of his work upon curves that have a dou¬ 
ble curvature, which he finiftied in 1729, at fixteen years 
of age. He was named joint-mechanician to the academy 
in 1731 at the age of eighteen, afl'ociate in 1733, and pen- 
fioner in 1738 ; during his connexion with the academy, 
lie had a great multitude of learned and ingenious com¬ 
munications inferted in their memoirs, befide feveral 
other works which he publilhed feparately 5 the lift of 
which is as follows : 1. On Curves of a double Curvature; 
in 1730, 4-to, 2. Elements of Geometry 5 1741, 8vo. 3. 
Theory of the Figure of the,Earth; 1743, 8vo. 4. Ele¬ 
ments of Algebra; 1746, 8vo. 5. Tables of the Moon ; 
3754, 8vo. His, papers inferted in the Memoirs of the 
Academy are too numerous to be particularifed here; but 
they may be found from the year 1727, for almoft every 
year till 1762 ; being upon a variety of fubjedts, aftrono-

were originally divided into many fmall tribes; and, when 
they came to parcel out the lands which they had con¬ 
quered, it was natural for every chieftain to bellow a por¬ 
tion, in the firft place, upon thofe of his own tribe or fa¬ 
mily. Thefe all held their lands of him; and, as the fafety 
of each individual depended on the general union, thefe 
fmall focieties clung together, and were diftmguiftied by 
fome common appellation, either patronimical or local, 
long before the introduction of furnames or enfigns ar¬ 
morial. But when thefe became common, the defen¬ 
dants and relations of every chieftain affirmed the lame 
name and arms with him : "other vafials were proud to 
imitate their example; and by degrees they were com¬ 
municated to all thofe who held of the fame fuperior.
