Song, and the pulp preserved in spirits. There should also be col- 
lected, gums, resins, and other productions of trees ; also seeds of 
plants not growing with us ; care being taken that they are perfectly 
ripe, and well wrapped up to defend them from moisture, or they 
will be useless. Nor should medicinal plants be forgotten, and 
those supposed by the inhabitants to be possessed of healing pro- 
perties ; together with a notice of the diseases in which they are 
used, and the mode of administering them ; vegetable poisons, 
with an account of their peculiar powers ; the woods employed for 
building, dyeing, &c. ; these may be a few inches long, and if prac- 
ticable the usual width of the tree; both a transverse, and lonoitu- 
clinal section should be made. Numbers should be attached to 
them, corresponding to those of the dried specimens, (from branches 
of the same trees,) in the herbal ; as we are still in ignorance with 
regard to what trees, many woods used in medicine, and the arts, 
belong. To all the above articles, notes should be added, men- 
tioning every important particular relating* to them. 
MINERALS. 
Specimens of rocks, stones, metals, volcanic productions, &c. 
whether handsome or not, whether the names are known or not, 
should be collected. Upon visiting localities, quarries, mines, &c. 
remember to take, in addition to the ores, &c. a specimen of the 
rock in which they are imbedded, together with all associated mine- 
rals. Gather all the particulars concerning the working of the 
mine, quarry, &c. that may prove interesting or useful. The size 
of specimens may be from one to four inches square, unless a petri- 
faction be enclosed, when the whole should be secured if possible. 
From volcanic districts, procure specimens of the various substan- 
ces thrown out by the eruption ; some being in the state of stone, 
others of glass, or of scorise, or of lava. Where earths containing 
organic remains are met with, such as shells, corals, bones and 
teeth of animals, fossil wood, impressions of vegetables, stems, 
roots, leaves, &c. specimens of the different articles should be se- 
cured, enveloped in the earth, or rock, in which they were fixed ; 
being of the greatest importance in stamping the character of the 
strata, orbed, in which they occur. The bones and teeth of ani- 
mals are not un frequently found in the more ancient gravels, and 
in the earth forming the floors of caverns ; the collecting of these 
from distant parts of the globe, is an object of the greatest interest 
to geology. Sands of shores, and rivers, should be collected ; and 
from the latter, as high up from their entrance into the sea as pos- 
sible. Whenever any insulated masses are found, supposed by 
the inhabitants to have fallen from the sky, or been transported 
from a distance, specimens should be taken therefrom, with a 
notice of all the important particulars relating to them. Speci- 
mens ought not, if possible, to be taken from loose pieces ; but 
from large masses in their original situation, or but lately removed* 
Fresh pieces should be broken off, as those that have been exposed
