varnifhers make ufe of, wet thoroughly a fheet of blotting-paper : 
difplay your fpecimen carefully on this paper, and prepare another 
fheet in a fimilar manner to lay over your plant. Then give a {mart 
preffure to your plant, either with a botanical prefs, a napkin prefs, 
or weights of any kind applied to the fpecimen placed between

paper below the fpeci jen, “and the fiie quantity above, to take up
