SPECIMENS OF PLANTS, 39 
to preserve, should be suffered to lie upon your table as long as 
it can be trusted without danger of its decaying, so’as to allow 
some part of its moisture to evaporate ; the thick and fleshy 
_plants should lie the longest, but the deliquescent ones, and 
those which are very thin and delicate, should be put into 
pickle almost immediately after they are gathered. ; 
Pour some of the Pickle into a spare jar, and into this im- 
merge the specimens to be preserved. The Specimens should 
remain in the pickle from three hours to three days, according 
to their bulk and fleshinefs.. Then remove each specimen into 
the jar in which it is to be kept, suiting the size of the Jars 
to the size of the Specimens. If they are of the large, juicy, 
and fleshy kind, fill up the jar with the stronger liquor, but 
the weaker will suffice for the smaller and thinner plants. 
Whichever liquor be used, the jar must be quite filled with it, 
and immediately corked very tight, Cover the cork and the 
top of the jar with Venice Turpentine, by means of a painter’s 
brush. In three or. four days the turpentine will become 
‘nearly dry, and then tie a piece of wetted bladder very tight 
over the top of the jar. These precautions are necessary to 
prevent the accefs of air, and the evaporation of the liquor : 
_ because, if either of these happen, the specimens will soon be 
spoiled. The Boleti are in general more difficult to preserve 
than the Agarics, and such of either as abound with a milky 
juice, are apt to foul the liquor, which must then be changed. 
Mofses and Lichens may be preserved in Ae perfection, by 
this method of pickling, :
