Marie de la Condamine. When the authorities of Lima induced 
some of the mathematicians to stay in South America, Vivier 
remained with Jean Godin, was employed in opening sulphur- 
mines at Cochabamba, and held for some time the chair of 
botany and mathematics in the College of Lima. In 1781 he 
obtained permission to return, and he embarked at Cayenne in 
1782. On his arrival at Paris he vainly sought to recover his 
former place in the laboratory of the Academy of sciences, and 
for some time lived in poverty, until he obtained a place in the 
library of the Duke of Penthiévre. His published works in- 
clude ‘‘Nova genera et species plantarum quas in America, 
Jac. Vivierus collegit” (3 Maes high: 1788-90) and “Sertum 
Peruanum” (2 vols., 1792); and his manuscripts contain a 
“Flora chilensis,’’ which has never oe published. 
[Wholly fictitious. It may be noted that this extaordiany 
man, who was born in 1720, was secretary of the La Condamine 
astronomical expedition, which went to South America in 1736! 
It is also a bit remarkable that, upon his return from Peru to 
Europe, he embarked at Cayenne!) 
WALLERTON, Charles Louis Auguste, French naturalist, 
b. in Sainte-Ménéhould in 1721; d. in Nancy in 1788. He was 
sent to Mexico in 1759 to study the botany of that country, at 
the suggestion of the Academy of sciences of Paris, and obtained 
a special privilege to enter the Spanish dominions. Landing in 
Vera Cruz in October, 1760, he explored the province of Micho- 
acan, where he formed a rich herbarium of medicinal plants, 
and afterward he searched the public libraries and the convents 
for information about the remedies that were formerly used by 
the Aztecs. He then visited the Isthmus of Panama, Santo 
Domingo, and Cuba, and made a thorough exploration of the 
latter island. On his return to France in 1765, with an her- 
barium of 1,500 medicinal plants, he was elected corresponding 
member of the Academy of sciences, and secretary of the Academy 
of Nancy, where he settled. He wrote “Traité explicatif d'un 
herbier de plantes médicinales recueillies dans un voyage 4 la 
Nouvelle Espagne, dans Visthme de Darien et a l'ile de Cuba” 
(3 vols., Nancy, 1767-70); ‘ ‘Monographie des maladies sy phili- 
ery et des simples en usage chez les anciens Indiens du Mexi- 
que”’ (1770); and “ Tableau de la flore du rovaume de la Nouvelle 
E Tere et en particulier de la province de Méchoacan”’ (2 vols.,
