THE MOST RECENT WORK. 



Strychnine Nitrate. — The product obtained 

 by dissolving strychnine in cold or warm dilute 

 nitric acid, and evaporating the solution, is in- 

 variably colored ; if, however, according to 

 Guigues (/. Pharm. ; Jour. Chem. Soc, 1894, 

 262) the alkaloid is suspended in hot water and 

 dilute nitric acid (1:5) added drop by drop until 

 the liquid is neutral and dissolution complete, 

 a colorless product is obtained on evaporation. 

 The crystals are anhydrous. Brucine nitrate 

 remains in the liquor. 



New Essential Oils. — Glechoma hederacea L. 

 (Ground Ivy) yields 0.03 per cent, of an essential 

 oil ; the Sp. Gr. is 0.925 at 15° C. ; the odor is 

 disagreeable and color is dark green. Apiiim 

 petroselinum L. (Parsley root) yields 0.08 per 

 cent, of an oil ; the Sp. Gr. is 1.049 ^^^^ separates 

 crystals (probably of apiol), even at the ordinary 

 temperature Essential Oil of Mignonette 



Root possesses characteristics which denote 

 that it belongs to the mustard oil group— it be- 

 ing, however, onlj' analogous. Its constitution 

 will be determined by subsequent experiments. 

 Asarum canadense L. (Canada snake 

 root), the fruit yields an oil soluble in 

 twice its volume of 70 per cent, alcohol. 

 Chenopodium ambosioides L. var. antheliminti- 

 ciim, Gray (American wormseed), the fruit 

 yields 1.03 per cent, of a light yellow oil, Sp. 

 Gr. 0.910 at 15° with optical rotation — 18°55' in 

 a 100 Mm. tube. The inference is that linomene 

 is present. The oil from the herb (0.35 per 

 cent.) is very similar but possesses a Sp. Gr. of 

 0.879 and optical rotation — 32°55'. Neither of 

 these oils gives a perfectly clear solution until 

 10 times its volume of 70 per cent, alcohol, but 

 age probably modifies them in this respect. Oil 

 of Solidago canadensis L. (0.63 per cent.) is 

 light yellow in color and possesses an agreeable 

 odor ; Sp. Gr., 0.859 and optical rotation— 

 2i°io'. Junipertis Wr^/w/flz/rt Z., the leaves yield 

 0.2 per cent, of a pale greenish-yellow oil with 

 an orange tasste odor, quiite distinct from that 

 savin; Sp. Gr., 0.986, optical rotation -1- 59°5'

Pottassium Iodide and Pottassium Bromide 

 G. W. C. Klie in a paper before the Missouri 

 Pharmaceutical Association, June, 1894, con- 

 siders these salts of the market and finds that 

 the large majority do not conform to the 

 requirements of the pharmacopoeia. The fol- 

 lowing is a tabular view of his results :
