          3.—ENTIRE PLANTS, or parts of them. Many have a very fleshy character, and ought to be preserved
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, Orchidaceæ, Misseltoe, Rafflesia, Mesembryanthemum, Cactus, Aphyteia, Balanophora, soft
Parasites, and others of a similar kind.

4.—TRUCKS of TREES, portions and sections of them, especially when they exhibit any remarkable structure:
as Polms,* and many other Monocotyledonous plants, Tree Ferns, Zamias, Cycas; and parasitical stems when exhibiting
the union with the tree on which they live. Specimens of Wood should be truncheons, five or six inches long, and
three of 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 RESINS, especially those employed in the Arts or in Domestic Economy.

7.—DYE STUFFS of various kinds.

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 collect and prepare them, what are the particular
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 well-dried flowering
specimens of the plants which afford them.

9.—GENERAL PRODUCTS of VEGETABLES. It would be extremely difficult, not to say impossible, to
enumerate all of these which a Museum ought to contain; but the enlighteded traveller can form a pretty correct
judgment. Such as are useful to mankind cannot fail to be interesting. It would be idle to exhibit every well
known object of this kind, Tea, Sugar, Coffee, Cocoa, Chocolate, Paper, Clothing, &c.; but there are states, even of
these familiar substances, which would prove both useful and instructive. The Cane of the Sugar might be advantageously
exhibited, along with the different qualities, manufactured from the Saccharum Officinarum. Specimens of
Chocolate 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 variety of vegetable substances, and the different sorts are well worth collecting;
from that afforded by the Papyrus of the Ancients (which gives the name) to what is manufactured out of the inner
bark of an East Indian Daphne (of Spurge-laurel), and another from the pith of an unknown plant in China (the
so-called Rice-Paper), or the leaves of a Palm in India, or Straw in North America. Of all such, the 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 Royal Mail, or Peninsular and 
Oriental Company’s Steamers, should be addressed:

“On Her Majesty’s Service. For the Royal Gardens, Kew.”
“to the Secretary of the Admiralty, LONDON.”

If by Merchant Vessels, or by private hands, to

“Sir William J. Hooker,”
“Director, Royal Gardens, Kew, LONDON.”

* Generally speaking it is desirable that a branch, dried and pressed, with flowers and fruit, should accompany the specimen, in proof of the exact
tree or plant from which it is derived. As yet we are ignorant of the Tree which yields the African Oak, or Teak, so valuable in the Navy!

Could I purchase at a moderate price specimens of American
woods named, a few inches in length & breadth, from any Carpenter
or Traveler-merchant.
