but in too small quantity for analysis. 

 On hydrolysis, it yielded a crystalline 

 substance, melting at 199°, which by 

 treatment with sulphuric acid at 160°, 

 was converted into eraodin. It was found 

 to be identical with the emodin mono- 

 methyl ether previously isolated from the 

 root bark of Ventilago madraspatamoe 

 (Trans., 1894.923). The other substan- 

 ces found were a small amount of free 

 emodin and a wax which crystallized in 

 colorless leaflets melting at 134 — 135°. 

 This latter was found to be identical with 

 the wax CisH.gO, present in the root bark 

 oi ih% Morhida iwtbellata (Trans., 1894, 



854-) 



An examination is being carried out of 



the constituents of the roots of the Poly- 



goniun bislorta and Rumex 7iepalensis, 



which are closely allied to this plant. —

Paste for ATTACHI^G I.abei^s to Glass. 



Oue ounce of flour rubbed to a smooth paste 

 with four ounces of water, then boiled, keeping 

 it well stirred, add five grains bichromate potas- 

 sium slowly, stirring all the time, then stand to 

 cool, makes a good paste for attaching paper to 

 glass. The paste must be kept in the dark and 

 used as soon as possible. Soak the paper in it, 

 and attach to the glas.=, then place in direct 

 sunlight for several hours. This sets up a chem- 

 ical change in the bichromate and renders the 

 paste insoluble. — Sci. Am. 



Paste for Bottle Labels. 



Dextrine impregnated with from 03 to o 5 

 per cent, of thymol, produces a paste which has 

 thus far proved all that can be desired for bot- 

 tle labels, etc., and which will not ferment. 



Removal of Ink Stains from Silk. 



Soak the spot in spiritsof turpentine and let it 

 stand for sometime; then rub it gently between 

 the fingers and the stain will come out and the 

 color and texture of the silk remain uninjured. 

 This can be done by stretching the silk and put- 

 ting a drop of the turpentine on it, renewing it 

 until the desired effect is produced. The stain 

 and odor of the turpentine will disappear in a 

 short time. — Sci. Am. 



SPIRITUS MYRCI/C. 



By Karl Schnackenberg. 



It is with reluctance that I make public my 

 opinion about this preparation, because any- 

 thing contained in the U. S. P. is, and ought to 

 be, a "touch me not." But if the jovial com- 

 mencement orators or banquet speakers are 

 correct as to the broad minded, high-spirited 

 pillar of the commonweal, the pharmacist — and 

 I am last to doubt their words— then one may 

 look critically upon our sacred guide and at 

 least attempt improvement when needed. 



Two objections may be raised against the 

 official Bay Rum : i. Faulty directions for pre- 

 paring. 2. The absence of color. Both have 

 been overcome in this manner : Dissolve the 

 oils in 220 Cc. alcohol, to remaining alcohol 

 (1000 Cc.) add 800 Cc. of water and the solu- 

 tion of oils, finally enough water to make two 

 litres. Thus the milky fluid, caused by addi- 

 tion of water to solutions of ethereal oils, which 

 is due to precipitation of terpines and may be 

 likened to resin-emulsions, is avoided, since a 

 clear liquid results, which may at times not 

 even require filtering. 



A colorless Bay Rum is not popular. A 

 rather unique coloring agent was finally stum- 

 bled upon : NH4OH, about 2-3 drops per pint 

 or 5 8 drops per L, produces a desirable yellow- 

 ish green tint. The addition of a few drops of 

 NH4OH to a pint should be a powerful argu- 

 ment as to the superiority and increased effi- 

 cacy of your Bay Rum to your homeopathic 

 friends ; hence do not omit it in your "ad." 



The elder Baron Rothschild had these rules 

 rules posted upon the walls of his bank.
