<28i1.] Instrument for nicasuring the Filaments of Wool. 34 
‘your readers, I think Iam competent to 
furnish them, through the medium of 
your valuablé miscellany, with five Eti- 
neraiies ; one for the South and West of 
England,—one for Wales,—one for the 
ANerthern,—another forthe Eastern,--and 
another for the Midland Counties ; com- 
prizing notices of all the most picturesque 
‘views, 
In return, T shall esteem myself in- 
ebted to ‘any correspondent, who will 
make out similar circuits, contaimng ac- 
counts of the different cplilections of pic- 
tures which lie along the routes. This 
must be done by some individual well 
equainted with the country ; as no book 
oof ‘Travels with which Iam. acquainted, 
.aifords satisfactory information on the 
‘subject. "The publication of a map con- 
taming such information, and entitled a 
Picturesque Map, thus including both 
uljects, would be a most acceptable 
present to English travellers. 
Although my own knowledge of col- 
dections, scattered through the different 
counties, isnot very extensive, it is suf- 
ficient to enable me to contribute to- 
wards the furtherance of the scheme. I 
ishallin a future communication, if agree» 
able, transmit the sketches of the routes 
above alluded to; but in the mean time 
LT hope that some correspondent will give 
a more complete list of the galleries of 
paintings in the country, than 1 feel 
anyself qualified to present. - ;

SIR, 
VYXHE Monthly Magazine entertains 
“@ and instructs us even heres” In 
the number for August, 1810, No. 969, 
* you describe an instrument for measuring 
‘the filaments of wool.” So early as 179 
“or 8, ah eye-glaés was applied to a scale 
“of equal parts, and used in obtaifing 
“these measures of different sorts,* “which 
“are published in the Treatise on Engli 
“Wools, printed for Hardinge about 1802, 
“The instrument, however, was a yer

coarse one, being constructed by my 
own hands, and, when applied to the 
finer kinds’ of wool, was by no means 
correct. In the same year, Meéssrs. 
Gilbert and Son, of Leadenhall street, 
made, under my direction, avery excels 
lent instrument, exactly answering to the 
one which yeu describe as recently ite 
vented. It was lost in 1806 out of my 
counting-house, at Leeds, and perhaps 
some one wishes to impose vpon the 
world as a novelty, that which has been 
obtained by dishonesty. Gilbert’s ins 
strument enabied me to discover the er- 
rors of former calculations, and correc- 
tions would have been made, had the 
treatise reached a second edition. Dr. 
Herschell, however, by applying a much 
higher magnifying powef, has performed 
the same service to the public, and with 
far greater precision than I could pos. 
sibly haye attained. His paper, if I res 
collect rightly, was. published in the 
communications tothe Board of Agvis 
culture, ar. Joun Luccock, 
Rio De Janeiro, December 30, 1810. 
To the Editor of the Monthly Magazines 
SIR, 
i> a Monthly Magazine for last’ year, 
you published’ the request of a cor- 
respondent, who wished to be inforined 
ofa methed to remove the shining qua- 
lity of Indian ink, which s6 much des 
stroys tlie effcet in drawings. 
The following means'will produce the 
desired effect :—break the’ ink into # 
phial with warm water, the “micilave 
will be so weakened (if ihe water is ih 
sufficient quantity) as to be no longey 
capable of suspending the colouring 
matter, which ‘will be precipitated to 
the bottom; the colourless ligior ma 
be poured off, and the remainder is fic 
for use divested of its shining quality. 
I have answered one quére, permit 
me to put another; some of your bota-= 
nical teaders'may favour it with notice — 
Are there any methods by which flowers 
may be dried or preserved, their parts 
not being injured by the process, which 
is the case by placing themis books, &é,
