1.7 per cent. The latter consists of glycerides of palmitic and oleic acids, also of butyric 

 acid and phytosterin; probably also a high molecular oxy-acid. — The odor of the root is carried 

 by a constituent of unknown composition, non-volatile with steam, soluble in ether but not 

 in petroleum ether. — A lecithin, containing palmitic and oleic acids and choline, is present. 

 The sugar is chiefly cane sugar (10.2 per cent); the invert-sugar content was 0.78 per cent. 

 The gummy portion contains numerous polysaccharides, 64 per cent consisting of glycosan. 

 Galactose is not present (as formerly held), but another saccharocolloid, which yields d-galac- 

 tose on hydrolysis, is present. — H. G. Barbour.

977. Greenish, Henry G., and Constance E. Pearson. A new source of santonin. 

 Pharm. Jour. 106: 2-3. 1921. — Artemisia brevifolia, found abundantly in western Thibet, 

 at an altitude of 9,000-14,000 ft., and in northern India from Kashmir to Kumaon at a some- 

 what lower altitude, yields at least 1 per cent of santonin. As far as is at present known, 

 santonin is not widely distributed in the genus Artemisia. Apart from A. maritima var. 

 Stechmanniana Besser, the unexpanded flower-heads of which constitute commercial santonica 

 and contain from 2 to 3 per cent of santonin, it has been found only in A. gallica. — E. N.

978. Harrison, C. W. The pharmacopoeial assay for alcohols in santal oil extended to 

 include the true acetyl value. Jour. Assoc. Official Agric. Chem. 4: 425-427. 1921. — The 

 method as submitted gives the ratio of the saponification number of the acetylated oil to the 

 acetyl value, and when expressed as santalol furnishes a significant figure for detecting 

 adulterations. — F. M. Schertz.

 following constituents, expressed in grams, were found: 7-linoleic acid 2.21, a-linoleic acid 

 33.65, ;8-linoleic acid 26.67, oleic acid 25.77, palmitic acid and high molecular acids 5.22, caproic 

 acid 0.78, unsaponifiable constituents 2.27. 7-linoleic acid was not previously described; 

 its hexabrom derivative has a melting point of 195-196°C. — H. G. Barbour. 



980. Hermann, E. Ein neuer Giftpilz. [A new poisonous fungus.] Pharm. Zentralhalle 

 61: 511-513. 1920. — Two cases of poisoning could be traced to the eating of a fungus which 

 at first was considered as Inocybe frumentacea or I. sambucina but later was determined by 

 Romell as I. lateraria. The fungus is extremely poisonous, patients dying within 2 hours 

 after previously suffering from vertigo, burning pain in the urinary tract, vomiting, and 

 blindness. Persons who have not eaten a fatal amount of the fungus become blind, but 

 regain eyesight within 24 hours. A detailed description of the structural characteristics 

 of the fungus is given. — H. Engelhardt.
