thort, he fhould-be fully aware of this 
trath, that by liftening to complaints: of 
this nature, not ouly w vould the eftablith- 
ment of feveral ufeful arts in’ France be 
prevented, but we fhould inféafibly drive 
Out of our cities, the farners, carpen- 
ters, joiners, brafiers, coopers, founders, 
weavers, and all thofe occupations which 
are more or «lefs difagreeable to - their 
neighbours. The right of toleration as 
been eftablifhed by- time. and neécefiity 
jet us not doubt; theréfore, but our 
manufactures,, when grown older, and 
better known, will peaceably enjoy the 
fame advantage i im fociety: in the mean 
tine we are of opinion; t 
ought to avail itfelf af this circumftance, 
to put themin a partieular manner un- 
der the protection of. government, and 
declare publicly that the manufacture of 
acids, fal-ammoniac, Pruffian blue, fugar 
ot lead, white iead, ftarch, beer, and 
leather, as. well as flaughter-houles, 
are not injurious to the health of the 
vicinity, when they are prepay con- 
ducted. 
“ §V¥e cannot fay as much for the ftcep- 
int of hemp, making cateut, layftalls, 
and, in general, efiablifhments where a 
larve quantiiy- of animal and vegetable 
matter is fubjeét to’ humid putretaction : ; 
in all thefe cafes, befides the difagree- 
able fmell which they exhale, miafinata, 
more or lefs deleterious, are evolved. 
“We muft add, that, though the ma- 
nufactories of which we have already 
fpoken, and which we have contidered as 
not injurious to the health.of the neigh- 
bourhooed, ought not to be removed, yet 
adminiftration fhould be requetted to 
watch over them ftri¢tly, and confult 
with well-informed pertons for prefcribjng 
to the conductors the moft proper mea- 
fures for preventing their fmoke and 
finell from being dittufed in the vicinity. 
This end may be attained by improving 
the procefles of the manufactures, rail 
ing the outer walls, fo that the vapours 
may not be diffufed among the neigh- 
bours; improving the management of 
the fires, which may be fh) to fuch a 
point that all the finoke fhall be cour 
in the fire-place, or depofited in the 
tunnels of long chimnies ; and maintain- 
ing the utmoft cleanlinefs in the manu- 
factories, fo that nothing thall be leit to 
putrify-in them, and all ‘the refufe cana- 
ble of fermentation be loft in deep wells, 
and prevented from any way incommadd- 
ig the neighbours.

ammomiac, leather, ftarch, or any other 
article by which vapours, very 1nconve- 
nient to the neighbours, or danger of 
fire or exploGions, are to he ‘eftablithed, 
it would be wife, juft, and prudent, to 
lay it down as a principle, that they are 
near 
dwellings, without fpecial authority ; 
and that if perfonus neglect to comply ~~ 
with this indifpenfable “condition, their 
mauufactories may be ordered to be re, 
moved withoutany indemnification. 
“Tt follows, from our report: Lt, 
That catgut manufactories,  layftalls, 
fteeping of hemp, and every efiablith- 
Ment in which, animal or vegetable mat- 
ters are heaped together to putrify in 
large quantities, are injurious to health, 
‘and ought ta be remote from towns and 
every lve elling-houie. . Qdly, That manu- 
factéries, where di fagreeable finells are 
occafioned through the action of fire, as 
in the making of acids, Prafhaw blue, 
and fi al-aramoniac, are dangerous to the 
neighbours only fon want of due pre- 
cautions; and that the care of govern~ 
ment fhould extend only to, an active 
and enlightened fupermtendance, having 
for its objects the ee ‘of their 
proceffes, and of the management of the 
fire, and the maintenance of cleaniu- 
nefs. Sdly, That it would be worthy a 
good and: wife vovernment, to make re- 
gulations, prohibiting the future eflabli{fh- 
roent of any manufac SHIRE the vicinity of 
which is attended with any eflential in- 
convenience or danger, in towns. and 
near dwelling-houfes, - without {pecial au- 
thority previowlly obtained. In this clafs 
may be comprized the manutactories of 
poudrette (dry night foil), leather, and 
{tarch; founderies, melt:agshoutes for 
tallow, flaughter-houtes, rag warehoufes, 
manufactories of Pruffian blae, varnith, 
glue, and fal-ammoniac ; potteries, &c.” 
Thefe conclufions were adopted by the. 
Inftitute, and addreffed to government, 
with an invitation ‘to make them the bafis 
of its decifions.
