Loridon, for the purpofe of extracting every 
kind of ink, printed or written, from 
paper of every fort, and remanufacturing it 
in the ufual way. Such an invention, 
which has long been a great defideratum, 
promifes to be of -confiderable benefit to 
the public, by converting to great ufe the 
aimmenfe mafs of wafte paper, which is 
every where to be found, and thus we 
hore, reducing the price of this moft ufe- 
ful article, which has of late rifen to fuch 
an extravagant height as to impede very 
materially the advancement of literature. 
A patent has been granted for this difeo- 
very, which we mean to give an account 
of in our next number., 
Paper already printed on, 1s now regu- 
_ Jarly bought in at the rag-fhops of foreign 
countries to be re-manufaétured by the pa- 
per-makers. Newipapers, old books, un- 
faleable books, can all be reduced toawhite 
pulp by the procefs of Madame Mafion. 
Tt is thus defcribed in a continental jour- 
nal. Choofe papers of fimilar hues to be 
ufed together. On one hundred weight 
of paper, pour fivehundred weight of boil- 
ing water. Stir it continually with in- 
dented paddles, until the whole is reduced 
toa pulp. Drain off the water through 
an opening covered with flannel, pour on 
frefh boiling water, and repeat the ftir- 
ring with inceflant induftry. Such of the 
component parts of the printers-ink as are 
not foluble in water, will fink to the bot- 
tom of the vat gradually; and the pulp 
will affume a whiter and whiter appearance, 
and may be removed in fhallow pails to 
be fubmitted to the ufual procefs of manu 
facture. This fortunate difcovery will be 
the grand defence of pofterity againft fu- - 
perfluous and tedious books. 
The quantity of paper-ftuff may in an- 
other manner be increafed. Inftead of 
making tinder from rags, it might be mace, 
as in France, from the agaric of the afh. 
The fungus is fliced thin, dried, beaten 
with a hammer until it becomes very elaf- 
tic, and boiled in water impregnated with 
falt-petre. In this ftate it readily catches 
fire from the fpark of a flint, and is fold 
very cheap at the fhopsby the name ama- 
dou. If this fubftance were eafily to be hac, 
the rags now burnt for tinder might be 
preferved. : 
C. Camszry, prefect of the department 
of the Oife, has written a circular letter to 
his colleagues, reyuefting them to lecond the 
defign of making a difplay of every thing 
* curious or interefting, and e{pecially of the 
objekts peculiar to fueh countries or de- 
partments. For this purpofe, it is pro-

pofed to engage a proper place, where ta- 
pettries, the produéts of other mannfac- 
tures, or of natural hiftcry, as foffils, 
piants, &c. may be fhewn to firangers tra- 
velling through thofe departmentsy The 
French are taking every method to revive 
the arts of France; and it may be faid, 
France itfelf, and the government of that 
country, aids every eftablifhment of this 
nature which is calculated to raife their 
country in the eyes of fereigners; and, in 
fhort, of exciting the curiofity of ftrangers, 
and inviting them to vifit the resublic. 
A curious fragment of ftatiftical theo- 
logy has appeared in Hungary: it is en- 
titled, Conftitutio. ret facre Unitariorum 
Jive Sociniancrum in M. Principatu Tranjil- 
vanie; quam vir P.Rev.Stephanus Lazar, 
Unitartorum Tranfilvanie Superattendens, 
defcripfit, 1795. It thence appears that the 
Unitarians in Siebenburgen havet ro parifh- 
churches and 54 chapels of eafe, which 
are diftributed into fix diocefes, fuperin- 
tended, according to the prefbyterian dif 
cipline, by fynods and confiftories. 
BoNAPARTE was prefident of the Na- 
tional Inftitute in its laft public fitting : 
inthat quality he has addreffed a very mo- 
dett and fuitable circular letter to the lite- 
rary focieties and univerfities of Germany, 
and accompanied it by the prize-quettions 
propoled by the mathematical and phyfical — 
clafles. 
taas and fon, bookfellers at Cologne, 
announce their defign to pubhifh a feries*of 
almanacks, the embelliff ments of which 
are to confift of copies from the piétures 
of Raphael, Correggio, Titian, Michael 
Anzelo, Rubens, and other admired maf- 
ters in the Mufeum at Paris. 
The common mode of faturatinge tho- 
roughly with carbonic acid the imperfectly 
faturated kali, has hitherto been to ex- 
pofe it for fome time to the air. Profefor 
Lowitz of Peterfourg effeéts this by fe- 
parating that part of the common kali 
which is free trom the acid, from that 
which contains it, One wayis by means 
of fulpbur. Diffolve a quantity of common 
kali in two or three pints of water, and 
add-by degrees to the folution boiling, pul- 
verifed fulphur till no more wall diffolve ; 
evaporate now the fluid by a gentle fire to 
the point of cryftallization, and purify the 
cryfials by repeated folutions, filtering 
and cryftallizing from the liver of fulphur, 
and the adherent kali, which is not fatu- 
‘rated with carbonic acid. The /econd mode 
is by means of acids. This feems to be 
very extraordinary; but it is a known 
fact, that acids firft combine themfelves.
