 ique et pharmacologique de la famille des Turneracees. (Organographic, anatomic and pharma- 

 cologic study of the family Turneraceae.) 270 p., 53 pi. Bigot Freres: l'aris, L919.] Hull. 

 Sci. Pharm. 26: 533. 1919. — The six genera of the family Turneraceae can easily be distin- 

 guished from each other by their anatomic structure. The author believes thai the Turner- 

 aceae must be considered as a special family, but if taken away from the Bixaceae, they should 

 be counted to the family Passiflorae. The author further deals with the medicinal use of tl e 

 members of this family, and especially of that of damiana (Turnera aphrodisiaca) and with 

 the various substitutes offered for this drug. — //. Engelhardt.

 vegetable adulterants. Jour. Amer. Pharm. Assoc. 8: 1032-1034. 1919. — The areas of the va- 

 rious tissues present are totalled by the aid of an ocular micrometer used in conjunction with 

 a stage micrometer and from these figures the author calculates the percentage of impurities. 

 The author gives method of examination for black pepper adulterated with pepper shells and 

 checks results obtained by measuring the shells and powdered kernel portions in a 10 minim 

 graduate. — Anton Hogstad, Jr. 



807. Hatcher, Robert A. Standardization of digitalis. A preliminary report. Jour. 

 Amer. Pharm. Assoc. 8: 913-914. 1919.— The author reports the results obtained by separ- 

 ating the principles of Digitalis into two groups, namely, the chloroform-soluble fraction and 

 the water-soluble fraction. The chloroform-soluble fraction was found to be more readily 

 absorbed and more lasting in its effects while the water-soluble fraction being more actively 

 emetic. Author believes that Digitalis should be assayed in reference to the chloroform- 

 soluble fraction and that this fraction may be made available for intravenous use, since it 

 mixes perfectly with water. — Anton Hogstad, Jr. 



808. Jones, J. Bay oil. Report on the Agricultural Department. Dominica, 1918-19: 5. 

 Imperial Department of Agriculture, Barbados. 1919.— Two samples of oil from varieties 

 of Pimenta acris, namely Bois dTnde and Bois d'lnde Citronelle, grown in Dominica, are 

 reported on. The latter variety contains a smaller percentage of Phenols, and has a strong 

 odour of citral, and the suggestion is made that it may have some commercial value in the 

 manufacture of toilet preparations. — J. S. Dash. 



S09. Jones, J. Camphor. Report on the Agricultural Department, Dominica, 1918-19: 

 5-7. Imperial Department of Agriculture, Barbados. 1919.— Results of distillations of 

 leaves, twigs and prunings from three plots showed that two of them were of true camphor 

 trees, yielding both camphor and oil, while the other was not, the material from it producing 

 oil only. — J. S. Dash. 



810. Keenan, G. L. The microscopical identification of mowrah meal (Bassia) in insecti- 

 cides. Jour. Amer. Pharm. Assoc. 9: 144-147. Fig. 1-3. 1920.— In the examination of prod- 

 ucts designated as ant and worm eradicators, author detected the presence of mowrah meal, 

 which he states resembles cocoa powder in general appearance. The powder consists largely 

 of the powdered cotyledons and occasional fragments of seed coat. Chloral hydrate reveals 

 the presence of yellowish-brown masses occurring separately as isolated fragments and also 

 in characteristic group arrangement. The uses of mowrah meal and a morphological 

 description of Bassia latifolia are also included. With bibliography.— A nton Hogstad. Jr.
