3 ENTIllE PLANTS, or parts of them. Many have a very Jleshj character, and ought to be presei-ved 
entire, in alcohol ; or portions of the stem and branches (according to their size) with flowers and fruit : such are the 
rare kinds of Stapelia, OrcMdacem, Misseltoe, Eafflesia, Mesemhryantliewmm, Cactus, Aphyteia, BalampJiora, soft 
Parasites, and others of a similar kind. 
4 TEUNKS of TEEES, portions and sections of them, especially when they exlubit any remarkable stracture : 
as p 'olms * and many other Monocotyledonous plants, Tree Perm, Zamias, Cycas; parasitical stems when exhibiting 
the union with the tree on which they live. Specimens of ;^d should b e truncheons , five or six inche^ng, and 
three or four in diameter, if the plant attains such a size. 
5 ^ ^WOODS. Specimens of the kinds used in commerce, for veneering, cabinet-work, or other useful purposes,, 
or such as recommend themselves by their beauty, hardness, or any other useful quality. 
6 — GUMS and EESINS, especially those employed in the Ai-ts or in Domestic Economy. 
7 — DYE STUEES of various kiiids. 
8 —MEDICINAL SUBSTANCES, These are of vast importance, and merit the attention of Travellers in every 
country Of many, it is not yet known, except to the natives who coUect and prepare them, what are the paiticular 
plants that afford them. It is hoped that the present application may be the means of dispelling this ignorance 
among scientific Europeans, and that Travellers will endeavour to procure the substances and weU-dried flowermg 
s^eciyuBfis of tlie plants wliicli alford them. 
g gENEEAL PEODUCTS of YEGETABLES. It would be extremely difficult, not to say impossible, to 
enumerate all of these which a Museum ought to contain ; but the enlightened traveller can form a pretty correct 
judgment. Such as are useful to mankind cannot fail to be interesting. It woidd be idle to exhibit every weU- 
knoTO object of tliis kind. Tea, Sugar, Coffee, Cocoa, Chocolate, Paper, Clothing, 8rc. ; but there are states, even of 
these familiar substances, which would prove both nsefrd and instructive. The Cane of the Sugar might be advan- 
tao-eously exhibited, along with the different qualities, manufactured from the Saccharwn Offkmaruni. Specimens ot 
aiocolate and Cocoa would be suitably placed by the large fruit to show that both are products of the same tree. 
Paper, again, is made from an infinite vaiiety of vegetable substances, and the different sorts are well worth MUectog;. 
from that afforded by the Papyrus of the Ancients (which gives the name) to what is manufactoed out of the inner 
bark of an East Indian Daphne (or Spurge-laurel), and another from the pith of an unknown plant in China (t e 
so-called Bice-Paper), or the leaves of a Palm in India, or Straw in North America. Of all such, fte several states 
of preparation should be collected and exhibited, not only as objects of curiosity, but as exemplifying the progress 
of Art and Science. 
Any Parcels or Packages which may come by Her Majesty’s Ships, or by the Eoyal Mail, or Peninsular and 
Oiiental Company’s Steamers, should be addressed : 
“ On Her Majesty's Servi ce. lor the Boyal Cardens, Kern. 
“ To the Secretary of the Admiralt y, LONDO N.” 
If by Merchant Vessels, or by private hands, to 
“ Sir William J. Hooker,” 
“ Director, Eoyal Gardens, Kew, LONDON. 
."Generally speaking it is desirable that a branch, dried and pressed, withflowers and fruit, should accompany the specimen, in proof of the exact 
tree or plant from which it is derived. As yet wc are ignorant of the Tree which yields tlm Afrlmn Oak. or Tmk. so valuable m the Navy .
