NOTE ON FUNGI EXSICCATI.

destroyed. The mere handling of the specimens in many instances 
is sufficient either to remove a slight pubescence, change the colour, 
alter the appearance, or in some one of many ways deteriorate the 
specimens. 
For these reasons, which we hold to be weighty ones, against 
which nothing equivalent can be suggested in favour of the present 
system, we urge upon the purchasers of exsiccati to estimate the 
value of their purchases by these considerations, and to bear in 
mind that good authentic specimens, to which the labels are in- 
dissolubly attached, are worth, both now and for ever hereafter, fully 
fifty per cent, more than loose specimens in packets; This is an 
aspect of the question worthy of the consideration of those who 
prepare exsiccati as a commercial speculation.
