BIOGRAPHICAL SKETCH OF MONSIEUR RENAULD. 
I. Theriot. 
Ferdinand Renauld was born on i8th November, 1837. He was educated 
at the College of Vetoul and at the Lycee of Dijon. He enlisted in a Spahi 
Regiment on 27th December, 1856, and serving in several cavalry regiments, 
worked his way up through the various ranks. But fever, contracted in 
Algeria, seriously undermined his health and hindered him in his career. He 
retired upon his pension as Captain in 1887, and was appointed Commandant 
of the Palace of Monaco the following year, which office he resigned in 1892. 
F. Renauld obtained several honors and distinctions: “ Chevalier de la 
Legion d’ Honneur”in 1884, “ Officier d’ Academie” in i88r, “ Officier de 
rinstruction publique” in 1884. In 1895 the “Academy of Science” gave 
him the Montagne Prize for his “ Prodrome de la Flore Bryologique de 
Madagascar,” and in 1905 the Detmazieres Prize for his “ Essai sur les 
Leucoloma.” He was correspondent of the Museum and a member of 
numerous learned societies. He died in Paris on the 6th May, 1910, after 
a long, painful illness, which he bore with admirable courage. His memory 
will be perpetuated in the Science of Bryology by the genus “ Renauldia” 
which Carl Muller named after him in 1891. 
The death of F. Renauld is a great loss to the bryological world in which 
he occupied an important position. He devoted nearly forty years of his 
life to Bryology, a science which he passionately loved. His first publica- 
tion “ Apergu phylostatique sur le departement de la Hte. Sadne” dates as 
far back as 1873. The following year he wrote his first article for the 
“ Revue Bryologique,” a review recently started to which, with the greatest 
zeal, he continued to lend till his death his most valuable co-operation. 
On glancing at the important work of F. Renauld, one is astonished at 
the variety of the subjects which he has treated and the importance of the 
studies with which he has enriched bryological science. 
First of all, he studied the flora of the countries where he lived, or which 
he frequented, the upper Saone; the Pyrenees; but this field was too narrow 
for his wonderful activity and so, from the year 1885, either alone or with his 
co-adjutor, Jules Cardot, he entered upon the study of exotic flora. His 
researches have special bearing upon North America and Africa (Madagas- 
car, and the neighboring isles, of the Congo, and the Canaries), and the 
result of his enquiries has been recorded in books which excite the admira- 
tion of all those interested in the science of Bryology. 
I will only briefly refer to the works which were prepared in conjunction 
with J. Cardot, not because their value is less, but because my friend, J. 
Cardot, influenced by a feeling of delicacy which all will understand, did not 
wish to undertake to draw up this eulogy of him, who has disappeared from 
this world, would blame me for not laying stress upon those of his works, 
which Renauld conceived and developed without assistance. I cannot, 
however, forbear laying stress upon the happy results of this co-operation of 
nearly a quarter of a century, for when this project of work, to be done in
