Biographical Account of M. ADRIEN DE Jussieu; by M. J. DECAISNE. 
(Extracted from the Memoirs of the Imperial Agricultural Society of 
France, for the year 1854.) 
In commencing a short notice of the Life and Labours of M. Adrien 
de Jussieu, a reflection occurs to my mind, which seems to bear pecu- 
liarly on the scientific career of our late illustrious colleague, while it 
explains and enhances our regrets. 
Tn science, as in all the various paths which lie open to human ac- 
. tivity, merit stands generally alone: it rarely descends from father to 
. son; and it would seem that the nobility of talent, which we all cheer- 
fully acknowledge, and which asserts itself by the benefits it confers, i$ 
still subject, like other aristocracies, to those alternations and reverses 
which remind us of the equality of human mature. If, by a rare ex- 
ception, we do occasionally behold instances of genius perpetuating 
itself through many succeeding generations, and even waxing brighter 
and broader as it descends, still, like all things here below, it has its 
marked close and limit, which it cannot overpass; it vanishes, and the 
. name which it had encircled with a halo of renown, remains but as 4 
legacy which is bequeathed to family affection and pride. 
The De Jussieus have been one of the privileged races in the intel- 
lectual kingdom. For a century and a half, from the days of Tourne- 
fort to the present time, they have figured in the history of Botany.
