was a center for growing medicinal herbs, but the industry was gradually replaced by bulb 

 culture. The plants mainly grown are Lap-pa major , Althaea officinalis, Datura Stramonium, 

 Digitalis purpurea, Hysopus officinalis, Ruta graveolens, Thyinus vulgaris, Salvia officinalis, 

 and Cochlearia Armoracea. Formerly the plants were dried in the open or in an attic; at 

 present they are treated in a more scientific way, though each grower uses his own method. —

1909. GiROLA, Carlos D. Plantas medicinales. Posibilidad del cultivo de las especies 

 exoticas en Argentina. Aprovechamiento de las especies indigenas. [Medicinal plants, culti- 

 vation of exotic species, and utilization of indigenous species in Argentina.] Bol. Ministerio 

 Agric. Nacion. [Argentina] 25: 1-46. 1920. — The author outlines the history of the study of 

 medicinal plants in Argentina. A list of plants that should be grown and studied is given. 

 A plan (to include the cooperation of all scientific institutions) is proposed for complete 

 studies of all medicinal plants. — John A. Stevenson.

 estimation of glycyrrhizin in licorice root and in licorice extract. Amer. Jour. Pharm. 93: 

 388-414, 455—481. 1921. — This is a translation, by Houseman, of the prize research paper of 

 the Hagen-Bucholz Foundation, 1913-1914, by Armin Linz (Arch. Pharm. 254: 65-134, 204- 

 224. 1916.— J-nton Hogstad, Jr. 



1911. Houseman, Percy A. Studies on licorice root and licorice extract. Amer. Jour. 

 Pharm. 93: 481-495. 1921. — The author discusses the Linz [see preceding entry] method for 

 the determination of the glycyrrhizin content of licorice root, also giving details of his method. 

 The published figures for glycyrrhizin in licorice root are too low. The author has obtained 

 10 per cent of glycyrrhizin for Spanish and Greek roots and 14 per cent for the Anatolian 

 with Russian and Chinese intermediate. — Anton Hogstad, Jr. 



1912. Knuth, Richard. Pelargonium oil. Amer. Jour. Pharm. 93: 302-315. PL 1, 

 fig. 1-4. 1921. — The author presents the 1st part of a comprehensive review of the rose- 

 geranium, yielding pelargonium oil, which is used as a substitute for rose-oil. The classi- 

 fication of the plant, with a review of the pertinent literature, is dealt with in detail. The 

 paper also includes a discussion of the morphological constitution of the glands; geographical 

 distribution of the rose-geranium; cultivation; quality and cultivation of the soils; propaga- 

 tion; diseases; harvest; distillation; proceeds and exportation statistics. [See also following 

 entry.] — Anton Hogstad, Jr. 



1913. Knuth, Richard. Pelargonium oil. Amer. Jour. Pharm. 93: 376-387. 1921. — In 

 this installment [see also preceding entry] the author discusses the chemical constitution of 

 the oil. Pelargonium oil is now known to contain the alcohols; geraniol, citronellol, linalol, 

 isoamyl-alcohol; a paraflfine; the terpenes phellandrene and pinene; a cyclic ketone; a men- 

 thone; a terpineol; a blue-colored high-boiling portion, and different paraffinic acids. The 

 author discusses the various constituents in detail. A bibliography is appended. — Anton 

 Hogstad, Jr. 



1914. Lerbna, Carlos A. Envenenamiento del ganado con plantas toxicas argentinas. 

 [Stock poisoning by plants of Argentina.] Surco [Argentina] 1*: 6-7. 1921. — The poisonous 

 plants of Argentina are listed, together with the symptoms produced, and the remedies recom- 

 mended. — John A. Stevenson. 



1915. Newcomb, E. L., C. H. Rogers, and C. W. Folkstad. Podophyllum ash standards. 

 Amer. Jour. Pharm. 93 : 429^32. 1921. — The results of the authors' studies on the ash content 

 and purity of 18 samples of Podophyllum show that there is considerable variation in the 

 proportionate amounts of roots and rhizomes, and that these parts are sometimes plump and 

 sometimes shriveled. Plump, starchy roots and rhizomes contain a proportionately small 

 amount of calcium oxalate and yield a low ash. Shriveled roots and rhizomes contain less 

 starch, proportionately more calcium oxalate, and yield a high normal ash. — Anton Hogstad, Jr.
