may be squeezed together, pressing out the watery par- 
ticles, drying these small cakes, and then putting them 
in the abovementioned cerate paper. Or small seeds mixed 
with dry sand, and put in cerate paper, packed in pro- 
portionate glasses, and covered with a bladder or leather, 
and all such glasses again packed in a vessel, filled with a 
mixture, consisting of half culinary salt, the other half 
of two parts of saltpetre, and one part of sal ammoniac, 
will keep the seeds cool, and preserve their vegetative 
power. 
Plants or shrubs that are to be transported, must 
be taken out with a lump of soil covering the roots, 
which must be wrapped in wet moss, surrounded with 
paper or a Russian bast-mat and packthread; plants 
thus packed may be put in a chest or box upon a 
layer of three inches deep wet moss in close rows, fill- 
ing up all vacancies with moss. Some holes or slips in 
the lid of the box, covered with bast-mats or sail-cloth, 
will give them air, and a direction must be fixed on 
top, to keep the lid uppermost, and the box in an open 
but shady airy place, out of the spray of the sea: the 
same caution, in regard to air and sea, must be taken 
with the boxes containing seeds. 
XII. Minerals, fossils, and petrefactions of all kimds, 
ought to be wrapt separately in papers, and the whole 
collection packed in hay, tow, hemp, or cotton, in a box, 
so that none of the specimens may touch or rub one 
another when the box is transported by land-carriage, 
or shaken by the rolling of the sea. Clays, earths, 
sands, and salts, are best preserved in glasses, or little 
glazed gally-pots covered with a bladder. Mineral wa- 
ters may be safely filled in glass bottles, immediately af- 
ter corked up and pitched, or covered with putty round 
the cork.
