Mr. FRANKLIN, of Newcaftle-upon-

will be at hand to illuftrate or advance any 
dubjeét of inquiry, or remark. ..At thefe 
meetings Mr. Nicuorson will regularly 
read a report on the ftate of natural philo- 
fechy and chemiftry, with regard to the 
New inventions which may from time to 
time be made; and will render every fer- 
vice to the fubfcribers which his.babits as 
an-operator, cr acquifiticns as a fcientific 
man, may enable him to do. The fub-

The difcovery of anew material

Rev. Mr. SsnGEr, of Reck, in Weftpha- 
ia; has already engaged the attention of 
the public. The Prufhan Government, in - 
commen with feveral eminent naturaltfts, 
Have thought it worthy of a particular 
examination. Therefult has been, that 
the aquatic plant, denominated by. Lin- 
nus conferva, affords one of the fitteft 
materials for the making of paper. In 
con‘equence of which the difcoverer,. befide 
the honour of a gratuity from the Court 
of Berlin, has obtained a patent’ for the 
manufacture of paper out of this fubftance.

his difcovery more generally beneficial, 
has publifhed-a circumftantial account of 
it under the following title: Die Aeltefe 
Urkunde der Papierfabrication ; wherein 
he treats in general of the invention of 
paper, and in particular of the method 
by which paper may be manufactured from 
the couferva. He'has added an elaborate 
hiftory of that vegetable, which, according 
to him, is a cryptogamic plant; and has 
demonttrated, that, next to rags, there is 
no’ fubftance in the vegetable kingdom fo 
proper for the manufacture of paper asthe » ”

fome rivers ceafe at times to generate. 
them, yet the cozferva grows every where

mony of many naturalifts, and efpecially d 
by that of the numerous German Flore.’ |)

being printed on coxferva-paper will afford a 
an opportunity of fairly judging what 
value ought to be fet on his imvention.
