52 LAMARCK, HIS LIFE AND WORK 
In the reports of the meetings of the Board of 
Professors there is but one reference to his blind- 
ness. Previous to this we find that, at his last ap- 
pearance at these sessions—z.e., April 19, 1825—since 
his condition did not permit him to give his course 
of lectures, he had asked M. Latreille to fill his place; 
but such was the latter’s health, he proposed that 
M. Audouin, sub-librarian of the French Institute, 
should lecture in his stead, on the invertebrate ani- 
mals. This was agreed to. 
The next’ reference, and the only explicit one is 
that) in the Gecords for May. 23511826, as follows: 
“Vu la cécité dont M. de Lamarck est frappé, M. 
Bosc * continuera d’exercer sur les parties confiert a 
M. Audouin la surveillance attribuée au Professeur.” 
But, according to Duval, long before this he had 
been unable to use his eyes. In his Systeme analy- 
tique acs Connotssances positives de 1’ Homme, published 
in 1820, he refers to the sudden loss of his eyesight. 
* Louis Auguste Guillaume Bosc, born in Paris, 1759; died in 1828. 
Author of now unimportant works, entitled : 7/¢stodre Naturelle des 
Coguilles (1801); Hist. Nat. des Vers (1802); Hist. Nat. des Crius- 
tacés (1828), and papers on insects and plants. He was associ- 
ated with Lamarck in the publication of the Journal d’ Histoire 
Naturelle, During the Reign of Terror in 1793 he was a friend of 
Madame Roland, was arrested, but afterwards set free and placed 
first on the Directory in 1795. In 1798 he sailed for Charleston, S.C. 
Nominated successively vice-consul at Wilmington and consul at New 
York, but not obtaining his exequatur from President Adams, he 
went to live with the botanist Michaux in Carolina in his botanical 
garden, where he devoted himself to natural history until the quarrel 
in 1800 between the United States and France caused him to return 
to France. On his return he sent North American insects to his 
friends Fabricius and Olivier, fishes to Lacépéde, birds to Daudin. 
reptiles to Latreille. Not giving all his time to public life, he devoted 
himself to natural history, horticulture, and agriculture, succeeding 
Thouin in the chair of horticulture, where he was most usefully em- 
ployed until his death.—(Cuvier’s £ loge.)
