[ 5 .]—LABELS FOR HERBARIA.—Should “Botanist” 
be obliged to have his own labels printed, the following form 
may be of use to him:—The plants to be mounted on car¬ 
tridge paper, placing above them the suborder or genera, 
and below, the species, common name, locus and tempus (or 
place where and time when gathered), and divide into fasciculi 
(orbundles).— AAncit Amok Pateije. 
Labels for herbaria can be had from G. Witt, King’s Lynn, 
at os. per 1000. I enclose one.—E. M. 
Mr. M. Beane recommends Newman’s Botanical Drving- 
paper as the best for herbaria purposes. It may be obtained 
at 9, Devonshire Street, Bishopsgate, price 15s. to 18s. per 
ream. He also says that a book of botanical labels was pub¬ 
lished by the Botanical Society of London, which might be 
obtained from Mr. Van Voorst, Paternoster Row; but he 
ithinks it is better to have a blank form of label printed, as 
-the duplicate labels in the book arc limited.

following:— 
01. Lavand. 5 xvj 
Ol. liosmar. yxvj 
01. Cassai §ij

It costs about 3s. per lb. 
[ 37 .]—EAU DE PORTUGAL.— J. F. (Aberdeen) in 
answer to a correspondent, sends the following recipe:—

Otto Rosse gtt. xv 
Sp. V. Rect. M. 
[39.]—LIQUOR COCCI.—A reply has been received from 
J. 1.11. similar to one given last week. 
[48.]—CRYSTALLINE POMADE.—" Utile ” (Boston) 
begs to inform A. H. C. that the following makes a good 
crystalline pomade:— 
R. Oil of Almonds 5 XX 1 V 
Castor Oil 3 viij 
Spermaceti §iv 
Palm Oil 5vj 
Oil of Verbena, 
„ Cassia, 
Otto of Rose, each ^Ixl 
Essence of Bergamot 5j 
Mix. 
[57.]—FLORIDA WATER.— Geo. Veanall, Chemist, 
Cranleigh, Surrey, can supply “Nemo” (Sudbury). 
[59.]—DISPENSING.—Although four replies have been 
made to this query, all of them have failed to notice the only 
point worthy of attention, viz. that the quantity of salts 
ordered is not soluble in a mixture containing one-fourth of 
its volume of rectified spirit, the heat generated by mixing 
K oz. of a rectified tincture with 4.V oz. of water being suffi¬ 
cient to keep the salts in solution for a time, but before two 
•doses had been taken the remainder would have set into a 
magma of small crystals. I fail to get the copious black 
precipitate noticed by your querist, the slight deposit there 
is being due to resin, etc., from the ginger slightly darkened 
by the iron.—J. H. Baldock, S. Nonoood. 
The peculiar black precipitate which M. Masson did not 
•discover (was his tinct. zingib. B.P. ?), but which ~ Magnesia ” 
and others found, is clearly accounted for by the action of the 
lerri sulph. on the resin, etc. of the tinct. zingiberis. The 
undissolved quime sulph. carries mechanically the result—a 
dark, resinous tannate (?) of iron—to the bottom of the liquid, 
leaving an almost discoloured solution of magnes. sulph. above. 
I cordially endorse 3 ’our opinion as to the impropriety of in¬ 
troducing acid, sulph. dil. in such a case.— Alpha. 
[61.]—TASTELESS PILLS.—With regard to the inqui¬ 
ries of two of your correspondents, I have been accustomed to 
coat mjr pills with a mixture of pulv. gum tragacanth and 
p. sacch. alb. in equal proportions. After having well shaken 
them with a small quantity of white of egg, and dusted them 
liberally with the powder I have named, they attain a slowly 
soluble coating, pleasant to the taste, and of smooth surface.

[63.]—GREEN FLUID FOR SHOW BOTTLES.—J". 
Barker (Sudbury) writes :—“ In answer to IF. IF., sulphate 
of copper and nitric acid, diluted with water, form a very pretty 
green. I have some now in my window, made in 1851, and 
it is perfectly bright and clear, and entirely free from any 
deposit whatever.” 
C. Fields (Stamford) and “Pestle and Mortar” (Dorking) 
recommend copper coins or wire treated with nitric acid. 
Chloride of nickel, diluted to the desired tint, is the best; 
chloride of copper also gives a good colour.— J. H. Baldock, 
S'. Nonoood. 
The following will give a good bright colour :— 
Solution of Cupri Acet. 
% Diluted Acetic Acid. 
Mix and add— 
Solution bichrom. of potass, q. s. to get the colour required. 
—H. Bland, Scarborough. 
A very beautiful and permanent emerald green can be 
obtained" by dissolving nickel in dilute sulphuric acid with 
heat.—P estle and Moetae. 
R. Cupri Sulph. partem unam 
Sodii Chloridi partes duas. 
Dissolve in water and dilute to desired shade.—H. Stokey. 
The following dce 3 not contain more than 5 grains of solid 
matter to the gallon, and can be altered in shade to any 
degree by the addition of the bichromate :— 
Liq. Fer. Perch. Fort. P.B. "iv 
Sol. Potass. Pruss. «lv

dually mix with the rose water, previously made warm.

Dissolve the isinglass in the water (in a water bath), then 
stir in the mastic previously dissolved in the sp. vini, and 
lastly stir in the oliba-num in the state of an impalpable powder. 
—J. W. Selwojb. 
Isinglass in strong acetic acid to the consistence of a paste 
gives a good, clear cement.— J. H. Baldock, S. Nonoood. 
[67.]—TINCT. PRUNI VIRGINIAN JE.— 
R. Wild Cherry Bark, bruised, 2 ounces. 
Proof Spirit, 20 ounces. 
Digest for fourteen days; express, and filter. Or the 
tincture may be better prepared by the process of displace¬ 
ment or percolation.— Alfked Utley. 
See paper by Professor Bentley on Primus (Cerasus) 
Virginians in PflARM. Journal, Vol. A r . Second Series; 
form for tincture, page 105. 
A similar answer has been received from J. M. Baldock 
(S. Norwood); and others from C. Fields (Stamford) and 
(S'. M. S. (AVeymouth), giving seven days for digesting. 
168.]—POT POURRI.—“ Iodif (Sudbury) would be glad 
of a recipe for making pot pourri.”
