BIBLIOGRAPHICAL NOTES. 
XXII1.—Dopertir-Tuovars. 
Louis Marm Avsert Ausert Duprrir-Txovars, the celebrated 
and teutiat eccentric botanist, was born in the Chateau de 
Boumois, near Saumur, Noy. 5th, 1758. 
He took to botany, he tells us («« Phyto eae [infra, No. 9], 
133), in October, 1780, and in 1788 had skete a ‘‘ Flore des 
Hnyitons de St. Malo,’’ and had studied more 5 patieuln the 
plants of Anjou. He claims to have furnished n o Merlet de 
la ae for his “ Herborisations ”’ a cit. p. 194, peor : 
In 1787, when on garrison duty at Lille, he was invited to joi 
a kant scientific society called the ‘ Collége des Philaléthes,”’ a nd 
to this ee wro ote his first published pamphlet, the ‘‘ Enchaine- 
ment des Htres.’ 
His brother Aristide, about 1790, endeavoured to equip an 
expedition in search of La Pérouse, but subscriptions sufficient to 
cover the cost not being received, the two brothers sold their 
patrimony and so raised funds. Their vessel was about to sail 
from Brest, when the Revolution broke out. Aubert was arrested by 
the revolutionaries on his way to the port, and Aristide only avoided 
join him at Mauritius. Aristide was, however, taken prone by the 
Portuguese at Fernando do Noronha and sent to Lis 
Aubert, on obtaining his release, sailed Oct. 2nd, 1792 (‘‘ Hist.
