FRANCE. 
Mr. Devctas has imported into 
France machines for the preparation of 
wool, and manufacture of cloth. The 
saving of Jabour resulting from the use 
of these machines was soon appreciated. - 
A certain nuinber of manufacturers have 
provided themselves with them; they 
have been encouraged and assisted, . 
either by premiums, or sums of money_ 
advanced them by government.- Still, 
however, it was wished that. every 
person might be at hberty to construct 
these machines, which the patent for 
their importation and improvement ob- 
tained by Mr. Douglas prohibited. The 
government therefore entered into a 
treaty with him,-and have allowed him 
such advantages as have induced him to 
relinquish the benefit of his patent: so 
that from the first of January, 1809, any 
one was allowed to -make and sell part 
er all of these different machines. _ 
At the sale of Merino sheep at Ram- 
bouillet, on the 16th of June, and fol-- 
lowing days, 69 rams and 84 ewcs' were 
disposed of, the former at the average - 
price of 705 francs, and the latter of 
433, which was considerably higher than 
what they fetched last year. The amount - 
of the sheep sold was 80,470 francs, 
and the_produce of the wool 6,85%, 
making a total of 87,327 francs.

between which and a second bottle filled 
with water, a communication was estab- 
lished by means of asiphon. Into the 
retort I introduced 22lbs. of sulphuric 
acid, concentrated to 66°. In the tu- 
bulure was inserted a particular kind ‘of 
funnel with two cocks, so that its pipe 
descended nearly to the bottom of the 
retort, passing through the sulphuric 
acid; 22@lbs. of . alcohol at 36° of 
Beaumé’s areometer were then poured 
in quickly, being conveyed through the 
acid by means of the funnel: The mix- 
ture was very well effected ; the distilla- 
tion. was kept up by means of a fire 
under the retort, and as soon as about 
4lbs. had passed over, 29lbs. of fresh 
alcohol, at 40° were introduced, drop by. 
drop, regulating the quantity as nearly as 
possible by what passed over into the 
receiver. . The process was continued so 
as to obtain 33lbs. of a fine white 
limpid product, of the most agreeable 
ethereal smell and tasté, containing no. 
traces of sulphurous acid, and yielding, 
when rectified on a water bath, 172 lbs. 
of pure ether, with some alcchol of an 
ethereal smell, well adapted for future 
processes. The residuum consisted of 
nearly the whole of the sulphuric acid 
employed, some aicohol, water, and pro= 
bably a certain quantity of ether com-
