MR. CROOK’S FOR SOAP-MAKING AND 
BLEACHING. 
A Patent was granted OStober 21, 
1799, to J. Crook, Chemilt, Edin- 
burgh, fora new foap, and new method of 
bleaching by volatile alkali ; and a new 
method of preferving feeds, and deftroying 
vermin. ie 
We have before had occafion to notice . 
Mr. Crook’s Patent for the preparation of 
foap from fifth; and the prefent may in 
part be confidered as a continuation of the 
former. The prefent improvement con- 
fifts in the fubftitution of volatile alkali, 
to the fixed alkalies which are commonly 
employed. The real difcovery in this 
patent is an economical method of prepar- 
ing volatile alkali: this is effected by di- 
getting ftale urine, or foot, with quick- 
lime: the alkali thus procured, is mixed 
Retrofpect of the Progrefs of the Fine Arts. Oar 
with fifh refufe, in the manner mentioned 
in the former patent. Mr. Crook has alfo 
found, that by mixing volatile alkali with 
the common black foap, it is hereby con- 
verted into a tran{parent yellow mafs, and 
in confequence its value much improved. 
For bleaching Mr. C. has invented a 
very fimple circulatory apparatus in clofe 
veflels, by means of’ which the fteam, im- 
pregnated with volatile alkali, is brought 
into clofe conta& with the cotton, &c. &c. 
by this procefs the goods are effectually 
bleached, 
The liquor for the deftruétion of vermin, 
and prefervation of feeds, is prepared by 
the diftillation of coal fchiftus, efpecially 
that kind which-is impregnated with ful- 
phur. The produét of this diftillation is 
a volatile vapor of fulphur, which is ren- 
dered {till more cauftic by the addition of 
quicklime : the feeds are fteeped in it, and 
the liquor itfelf is poured on places infeft-: 
ed with vermin, which it effectually de- 
{troys. ;

MONTHLY RETROSPECT or toe PROGRESS or THE 
. FINE ARTS. ge 
O contemplate the Progrefs of the 
Arts in this commercial and {pirited 
country, affords fome exercife to a philofo- 
phical mind: for it is a curious circumftance 
that war,which in other nations hasgeneral- 
Jy overwhelmed and deftroyed all the imi- 
tative and elegant arts, has in this only al- 
tered’ their courfe, and driven them into 
another ftream, where, though they do not 
flow with quite fo rapid a current, they 
neither freeze nor ftagnate. 
Is an Admiral victorious,—the people 
whom his prowe($ has exalted, are eager to 
record his valour, and tran{mit his name to 
the lateft pofterity.x—Sculpture and paint- 
ing emulate eachother in blazoning his 
achievements, which being thence tranf- 
ferred to the copper, are diffeminated over 
a large portion of the civilized world. 
This fame, though flattering to thofe on 
whom it -is conferred, is, it muft be ac- 
knowledged, of too flimfy a texture. Of 
the defeat of the Spanifh armada it was 
thought proper to give a general reprefen- 
tation in tapeftry: the prefent age, with a 
{pirit which does it honour, defirous of en- 
rolling the names and aétions of its herce 
00 more durable materials, have entered 
ito very liberal {ub{cription to defray the 
expence of erecting a naval pillar, to com- 
Mmemorate the victories of our naval com- 
manders,. The {ubfcription govs on well, 
Monriity Mac, Noy Lu, 

and we hope this column, fo honourable to 
Britith courage and gratitude, will be cre- 
ditable tothe national tafte,  ~ ~
