77ie Decimal System. —I beg to inquire of your correspondent of last month, who 
approves of the decimal system of computation, how he would represent the value of 
any one of the following articles:—Three loaves bought for a decimal shilling, twelve 
bottles of wine bought for forty decimal shillings, or three horses bought for a hundred 
decimal pounds ? The fact is, that this system is absolutely unable to express the 
exact value of any one of these, and only the approximate value by much torturing and 
many figures. Further, it can only give the value of tenths and fifths (and of course 
halves) in whole figures, quantities that, by the experience of ages, are rarely required. 
—Robert Howden. 
J. T. L. (Bristol).—A little conserve of hips, or manna, will answer the purpose. 
J. H. IF. (St. Alban’s) wishes to know what are the medicinal properties of Nitrate 
of Furfurine. 
“ Speculum ” (Stroudwater).—Rub down the gallic acid, which is sparingly soluble, 
with the dilute sulphuric acid and a little of the decoction, then add the other ingre¬ 
dients. The copious precipitate observed in the mixture cannot be avoided. 
T. A. N. —(1.) Remedy for Cholera ordered hy the Board of Health , see Vol. VIII 
(n.s.) pp. 85 and 170. (2.) Dr. Attfield’s ‘ Pharmaceutical Chemistry.’ 
J. T. T. (Richmond, Yorkshire).— Glycerine Jelly. Vol. XVII. p. 400. 
T. E. (Salford).—(1.) No. (2.) Yes. 
“ Junior ” (West Bromwich).—No. . 
J. B. P. (Wakefield).— The specimen arrived much injured, but it appears to be 
young state of Filago germanica. 
B. Y. (Bristol).—A new edition is preparing and may be expected to appear about 
January. 
R. S. (Crosby).—The cubical crystals you find on extract of stramonium are chloride 
of potassium. 
Botanist (Lincoln).—In January next. 
“ Iota ” (Perth).—(1.) It matters little as to the order in which the ingredients are put 
together, as in any case the quinia will be thrown out. (2.) We presume that a solu¬ 
tion in rectified spirit is required ; and when this is not the case a formula for an aqueous 
solution is given in the same work. 
u Santonica ” (Macclesfield).—Santonine is generally given in doses of from 2 to 4 
grains, either in powder or in the form of lozenge. 
W. J. D. (Portsea).—Yes; but the label forwarded would render you liable to the 
Patent Medicine Duty. 
W. L .—(1.) We know of no published formula for Liq. Potassce Hypophosphitis. The 
strength of Taylor’s solution is 5i of the dry salt in jiv of solution. (2.) Tincture of 
Virginian Prune , Vol. V. (New Series), page 105. 
Substance for Lighting Cigars by Blowing .—Mr. Hunter (Glasgow) sends the following 
formula in reply to F. G. (Devizes) in our April number:— 
“ Plumbi Acet. ^ij; Acid Tart. 5 iv. Dissolve these powders separately in distilled 
water. Mix the two solutions, collect the precipitate, and when dry put it into a bottle, 
which is to be introduced into a crucible filled with sand, and exposed to a red-heat 
until the bluish vapour at the mouth of the bottle is no longer visible, when a light is 
applied. It is then taken off and allowed to cool, and kept in a well-corked bottle. It 
is used by applying it to the point of a cigar, which is drawn briskly through the air.” 
We would recommend caution in the use of this substance. 
Mr. G. Shepperley (Nottingham) is thanked for his communication. 
W. L. G. (St. Austell).—About 5ss of acetic acid, B. P. 
Several articles are unavoidably postponed.
