These collections of Study are proper for Museums, 
Scientific Institutions, and Schools, as well as for every 
person who desire to study natural history. 
They contain many rare species and my purpose in dis- 
posing of them at so low a price is to make them accessible 
tQ. every §|§£|^)^^ 
This Study will procure infinite enjoyment to all those 
] who will dedicate themselves to it. 
With love of collections, there is no more useless walk, all 
is interesting each day you discover new marvels of nature. 
They are very good for acquiring order and knowledge 
and you become useful to your country by your disco- 
veries . 
Who can deny that the greatest part of the revenues of 
all governments is due to those learned men who have 
dedicated themselves to this science? 
Coton, tobacco, potatoes, coffee, tea, indigo, cochineal, silk 
are all products of nature and some travelers (mostly natu- 
ralists) are those who have been to search for ; sometimes 
in very remote countries and to the cost of their lives, to 
try their acclimatation in their country or to make appre- 
ciate their value and their goodness.
