§ jy. A certain number of plates will be publifhed 
every month, not fewer than fix, nor more than 
twelve. 
§ 1 8. For each parcel of plates, a certain price 
will be fixed, according to the number, each plate 
at the rate of ten creutzers j fo that fix plates will fell 
for a florin of the Rhine, according to the value it fhall 
go at, when the plates are publifhed ; which price, 
though by no mean great, yet, it is to be hoped, that, 
after the fale of fome parcels, the reft may be fold 
ftill cheaper. 
N. B. The florin, here mentioned, is worth about 
two (hillings Englifh ; and therefore, each plate 
will fell for about four pence. 
There is no room for fufpicion, that this work 
will not be completed, as too often happens in this 
way of publifhing by parts : for, as far as human 
forefight can go, every thing is fo prepared and or- 
dered, that there can be no reafonable doubt that the 
work will be continued, and finifhed. 
Laftly, As the intention of this work, fays the au- 
thor, is to facilitate the knowledge of the genera and 
fpecies of Fungi, as much as polfible; that we may 
be better inftrudted by perfons fkilful in this affair ; 
by what name they judge it is called by authors not 
now living ; by what name it is vulgarly known in 
their own country; and what ufe is made of it amongft 
their countrymen, and in what manner. 
For thefe ends, fays our author, the Electoral Aca- 
demy enjoined me to apply to academies, literary fo- 
cieties, and men of learning, either fkilful in natural 
hiftory, or promoters of it, in other countries, defiring, 
that they will be pleafed to communicate any obfer- 
a vations
