2123. Albes, E. Scented soap from Paraguay oranges. Sci. Amer. Supplem. 88: 382-383. 

 o fig. 1919. [From the Pan American Ujiion.} — Concerns the distillation of oil of petit grain, 

 used for scenting toilet soaps, from the leaves of the bitter orange or bigarrade (Citrus bigar- 

 adia). There are between 30 and 40 factories operating in Paraguay, employing rather primi- 

 tive stills. From 500 to 600 pounds of leaves are required to produce about a quart of the 

 ordinary oil of petit grain. The average still will produce about 4 quarts per day. In 1913, 

 the amount of oil exported was 71,322 pounds. — Chas. H. Otis. 



2124. Anonymous. A new source of vegetable oil. Sci. Amer. 122 : 399. 1920. [Extract 

 from the Bull. Imp. Inst. United Kingdom Great Britain.] — Note on a semi-siccative oil from 

 the seeds of Lactuca scariola, var. oleifera. — -Chas. H. Otis. 



2125. Bargellini, G. Sul 1-2-3-triossiflavone. Contributo alia conoscenza della costi- 

 tuzione della Scutellareina. [On the 1-2-3-trioxy-flavone. Contribution to the knowledge of 

 the constitution of Scutellarein.] Gaz. Chim. Italiana 49: 47-63. 1919. 



2126. Bargellini, G., and E. Peratoner. Sul 1-3-2' triossi-flavonolo. Ricerche per 

 la sintesi della Datiscetina. [On 1-3-2' trioxy-fiavonol. Researches on the synthesis of Datis- 

 cetin.] Gaz. Chim. Italiana 49: 64-69. 1919.— See Bot. Absts. 5, Entry 2160. 



2127. Cauda, A. Contenuto in essenza dei semi di senape. [Essence content of mustard 

 seeds.] Staz. Sperim. Agrarie Italiane 52: 122. 1919. — A short note on the total content of 

 essence in seeds of different species and of the same species cultivated in different regions. 

 Brassica alba, B. nigra and B. carinata were studied and the determination made by bromine 

 oxydation in a paraffin bath and subsequent weighing as sulphate. B. nigra seeds were found 

 to contain a higher percentage of essence than B. alba and B. carinata while seeds from plants 

 grown in northern localities contained greater percentagesthan the seeds from plants grown in 

 southern regions. Size of seed seems also to have an influence, the smaller having a higher 

 percentage than the larger. — A. Bonazzi. 



2128. Cohn, Edwin J., Joseph Gross, and Omer C. Johnson. The isolectric points of 

 the proteins in certain vegetable juices. Jour. Gen. Physiol. 2: 145-160. 5 tables, 8 fig. 1919. 



2129. Cusmano, G. Sui principi ipotensivi del Viscum album. [Hypotensive compounds 

 of Viscum album.] Gaz. Chim. Italiana 49: 225-228. 1919. — The author prepares a solution 

 of the substances found in Viscum by dialyzing a decoction of fresh leaves with water. The 

 hypotensive components pass through the membrane, and their solution thus obtained is con- 

 centrated on a water bath and extracted with alcohol (96 per cent). At first there is the 

 formation of a homogeneous mixture, but on standing two strata are separated and the lower 

 one is discarded. The supernatant liquid is again concentrated and again extracted with 

 alcohol. As a guide for the separation of the hypotensive compounds the author used the 

 method of injection in the blood stream of the dog. — A. Bonazzi. 



2130. Dodd, Sydney. St. John's wort and its effects on live stock. Agric. Gaz. New 

 South Wales 21: 265-272. 1920. — Deals with the effect of a plant, probably Hypericum 'per- 

 foratum, upon the different classes of live stock. Sensitized areas appear upon the body, espe- 

 cially where pigment is deficient. Develops mainly under conditions of insolation. Feeding 

 experiments are described. — L. R. Waldron. 



2131. McAtee, W. L. Notes on the flora of Church's Island, North Carolina. Jour. 

 Elisha Mitchell Sci. Soc. 35: 61-75. 1919.— See also Bot. Absts. 5, Entry 2419.
