" However, he has said in the same work (t. i. 
p. 132), ' I believe that I may affirm, without vio- 
lating propriety, that I have given a proof of my 
devotion to science. ]\Iore than half a century has 
elapsed since I began to cultivate it; but it has 
amply rewarded me for the efforts and sacrifices I 
have made on its behalf. There exists only one 
chair of Entomology in Europe, and I am the first 
who has filled it.' 
" Yes, but the indefatigable labour of half a cen- 
tury was necessary to obtain it ! 
" Thanks to you, Gentlemen, Latreille could have 
said, at a later period, ' There exists only one Ento- 
mological Society in Europe, and I am the first who 
presided over it.' 
" If it be true that the life of a man ought to be 
estimated only by the use he has made of it, that of 
Latreille is worthy of envy, since it was spent so 
worthily. Let us cherish his memory, and study 
his writings." 
Latreille's Collection of Insects, which was exten- 
sive, was sold after his death. The Coleoptera were 
purchased by Mr, Noris of Manchester.
