cording to size,) in alcohol, as rum, arrack, or in diluted 

 pyroligneous acid or strong brine. — 2. Entire Plants, or 

 parts of them. Many have a Ytry 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 as those of Palms, Stapelia, Jiafflesia, and others of a 

 similar kind. — 3. Trunks of Trees, portions and sections 

 of them, especially when they exhibit any remarkable 

 structure ; as Palms, and many other Moitocotykdonous 

 plants, and Tree Ferns. Specimens of Wood should be in 

 sections, a foot or more Ions, and about the average 

 diameter of the tree. 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 valuable quality, are particularly desired. T/ie 

 scientific or other names should be attached, and specimens of 

 the leaves and flowers to identify them. — 4. Gums and 

 Resins, Vegetable Waxes, especially those employed in 

 the Arts or in Domestic Economy. — 5. Dye Stuffs of 

 various kinds. — 6. Medicinal Substances. These latter 

 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, nor how they are prepared. 

 — 7. General Products of Vegetables; in the state of 

 the raw material, and manufactured. 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 would be 

 idle to send every well-known object of this kind. Tea, Sugar, 

 Coffee, Cocoa, Chocolate, Paper, Textiles, Platting, Basket- 

 work, Clothing, St'c; but there are states, even of these 

 familiar articles, .which will prove both useful and instruc- 

 tive. Paper, for example, 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 (or Spurge- 

 laurel), and another from the pith of a little known plant in
