THE NEW PATENTS. 
Enrolled in

Patentees are requefted to favour the Editor with Copies of their 
Specifications, or with a concife Account cf their Inventions, as ) 
early as convenient ofter the Ttme of Enrollment. - i 
Lorp DuNpoNALD’s MreTHOD OF 
MAKING CERUSE, OR ~WHITE 
LEAD. 
N the 18th of Auguft, letters patent 
were granted to the Right Hon. 
ARCHIBALD Lord DUNDONALD, for 
a method of making Cerufe, or White 
_ Lead. ; 
Numerous are the modes employed in 
the preparation of lead for the ordinary 
cerufe; and in proportion to the improve- 
sent of the colour, and the manner In 
which it is effeéted, approaches to mo- 
deration of price, the more valuable will 
the difcovery be to the patentee, and ul- 
timately to the public. White lead was 
formerly obtained by means of the fu- 
rpigation of vinegar, on common lead, 
placed for a certain time in earthen pots. 
Lord Dundonald has, however, difcover- 
ed a more expeditious and facile method, 
which becomes.the more ufeful, as the 
fubftance with which it is effected, has 
been hitherto rejected by the chemical 
world .as a caput miortuum. 
His Jordfhip directs common lead to be 
reduced to a calx—burt not too fine—and 
to have a proportion of five-fixth parts 
thereof, ‘intimately mixed with ma- 
riat, or folution of pot-ath. In this 
ftate, he direéts it to be frequently ftir 
red, in order to have the new furfaces of 
the mixture expofed to the carbonic acid 
of atmefpheric air; as his lordfhip. ob- 
ferves, that the effect of the carbonic acid 
on the alka'i exifting in the prefent ftate 
of the mixture, is effentially neceffary, 
in order to effeé& the intended purpofe. 
In this ftate,it is to be frequently fprink= 
led with water, and after the calx has 
been long enough immerfed with the 
muriat to be fufiiciently operated upon, 
the muriat, is to be levigated by common ~ 
water from the calx, and to be concen, 
trated by evaporation, in order to be 
made ufe of ata future period with other 
calx. The patentee direéts the calx to be — 
afterwards ground, levigated, and dried 
for ufe, nrg Ys 
The fuccefs which has attended the 
former patents of this intelligent nobles 
man leads us to conclude, that the pre= 
fent one is entitled to the attention of the 
public. :
