1919. — A description of the macroscopic and microscopic characteristics of tin' fruits of An 

 ica Archangelica, F. Narthex, F. galbaniflua, F. angulata, Pastinaca $ativa, HeraeU van Sjx - 

 dylium, Laserpitium Siler, L. marginatum, Opopanax chironeum, and haunts Carota. Angel- 

 ica Archangelica is winged and its mesocarp is composed for the most part of loosely arranged, 

 porous and reticulately thickened parenchyma with large intercellular-air-spaces; its vittae 

 are distributed above the inner epidermis and in the ribs. Ferula Narthex shows B band of 

 thick-walled, punctated cells in the inner mesocarp and giant vittae in the mesocarp. /•'. 

 galbaniflua is distinguished from F. Narthex by having vittae in the ribs as well as the meso- 

 carp. F. angulata possesses vittae in mesocarp and ribs, its outer epidermis and the cell 

 layers lying directly beneath are strongly thickened but not woody, and hesperidin crystals 

 exist in all the epidermal cell glands. Pastinaca sativa shows vittae alongside vascular bun- 

 dles, a sclerenchyma band in the inner mesocarp and finely punctated parenchyma in its 

 winged ribs. Herecleum S pondylium has a sclerenchyma band in the inner m'esocarp and finely 

 punctated thick-walled parenchyma in the wings outside of the bundles. Laserpitium mar- 

 ginatum has elliptical vittae while those of L. Siler are triangular, as viewed in cross section. 

 Opopanax chironeum shows cells of epidermis, wings and within vascular bundles with ellip- 

 tical punctations; Daucus Carota has delicate spines growing from secondary ribs, and bristle- 

 hairs only on primary ribs. [See also next following Entry, 832.] — 11. W. Youngken. 



832. Styger, Jos. Beitrage zur Anatomie des Umbelliferenfruchte. [Contribution on 

 the anatomy of Umbelliferous fruits.] Schweiz. Apotheker Zeitg. 57: 243-250. 1919. — An 

 analytical key, based upon a pharmacognic system, to the 50 Umbelliferous fruits described 

 by the author in preceding pages of this serial. These are placed in 3 main groups, viz. : 

 I. Without oil containing elements. II. With secretion sacs. III. With oil reservoirs (vit- 

 tae). The first two of these captions have but one representative each, viz.: Conium macu- 

 latum and Hydrocotyle vulgaris respectively. The third group includes two subdivisions: 

 1. With commissurral vittae only. 2. With dorsal and commissural vittae. Further group- 

 ing of these subdivisions is based upon presence of one or more vittae in mesocarp, scleren- 

 chyma plates, hairs, strongly thickened and lignified parenchyma elements in mesocarp, sec- 

 ondary vittae, and distribution of the vittae in inter-rib and rib regions. [See also next 

 preceding Entry, 831.] — H. W. Youngken. 



833. Suttox, Richard L. Ragweed dermatitis. Jour. Amer. Med. Assoc. 73: 1433- 

 1435. 1919. — The important part played by anaphylaxis in the causation of various eruptions 

 has long been recognized. Anaphylaxis has been defined as "a state of hypersusceptibility 

 of the organism to foreign substances, which is brought about by the introduction of certain 

 foreign substances and their cleavage products." C. Walker has pointed out that certain 

 proteins, including those of ragweed pollen may cause dermatitis in predisposed persons. 

 The author describes four cases of ragweed dermatitis. In two of them the common ragweed. 

 Ambrosia elatior, was the chief offender. The giant ragweed, A. trifolia, the mupwort, A. 

 psilostachya, and the bur marsh-elder, Iva xanthifolia, probably occupy lesser roles. All 

 have been shown to cause hay fever. Pollen vaccine treatment gave beneficial results. —
